Canada's Adaptation and Mitigation to climate change

The Fifth National Communication on Climate Change 2010 shows two very proactive examples that Canada is undergoing to adapt to future impacts of climate change. These two examples below are directly from Canada's 2010 (PDF) NC5 report:

1.       Energy efficiency: Canada is amending energy efficiency regulations under the Energy Efficiency
Act to introduce new performance standards on products accounting for 80% of the energy used
in homes and businesses in Canada. Governments in Canada are also implementing a wide range
of energy efficiency programs for consumers and businesses, and exploring the potential of smart
grids.


2.       Since 2006, Canada has also been developing a comprehensive, market-based regulatory regime for GHG emissions from major industrial sources. In 2009 Canada indicated it would review this proposed regime to align with the emerging cap and trade program in the United States. Aligning our climate change policies and measures with those of the US is a critical element of Canada’s overall approach, in light of the close integration of our two economies and our geographic proximity.

National Reports for Less Developed Countries (non-Annex I): http://unfccc.int/national_reports/non-annex_i_natcom/items/2979.php


The IPCC's adaptation section makes an interesting point when it shows that the U.S. and Canada have to work together both politically and financially, mainly because of the close proximity of their geographic locations.  However, in working together they have to somehow learn how to respond to the adaptation evidence that is available without thinking about their own interests.  This statement really illustrates the result of their recent attempts:

"Canada and the U.S. emphasize market-based economies. Governments often play a role implementing large-scale adaptive measures, and in providing information and incentives to support development of adaptive capacity by private decision makers (UNDP, 2001; Michel-Kerjan, 2006). In practice, this means that individuals, businesses and community leaders act on perceived self interest, based on their knowledge of adaptive options. Despite many examples of adaptive practices in North America, under-investment in adaptation is evident in the recent rapid increase in property damage due to climate extremes (Burton and Lim, 2005; Epstein and Mills, 2005) and illustrates the current adaptation deficit." (Retrieved from <http://www.ipcc.ch/publications_and_data/ar4/wg2/en/ch14s14-5-1.html> )

The article below is taken from Government of Canada's website regarding climate change; particularly their involvement with the Kyoto Protocol - http://climatechange.gc.ca/cdp15-cop15/default.asp?lang=En&n=72499914-1

"The Kyoto Protocol was adopted on December 11, 1997 and entered into force on February 16, 2005. 184 Parties of the Convention have ratified its Protocol to date. Canada signed the Protocol on April 29, 1998 and ratified it on December 17, 2002. 
Under the Kyoto Protocol, Canada's emissions over the 2008-2012 period are limited to 2,791 megatonnes of carbon dioxide equivalent.  As is the case for a number of other Parties to the Kyoto Protocol, our emissions are projected to exceed this agreed limit."

This article above was written on 8-10-2010, and since that time Canada withdrew themselves from the Kyoto Protocol, stating several valid reasons. First, they pointed out that it was a platform that started with “30% of the top C02 emitting countries, and in 2011 had about 13%" and is slowly dwindling.  Second and one of their main concerns is that the United States and China are not committing to this protocol which makes the platform null and void because the U.S. and China are the world's top C02 emitting countries.  This link (http://www.bbc.co.uk/news/world-us-canada-16151310> ) will show the interview with Canada's Environment Minister Peter Kent, where he plainly states that the Kyoto Protocol "does not represent a way forward for Canada and the country would face crippling fines for failing to meet its targets.".

Canada's efforts towards mitigating climate change are targeted at collaboration with the world's top C02 emitters to form a plan that will work for the world as a whole.  This is one of their motives for withdrawing from the Kyoto Protocol, because not only would it cost the countries involved money to try and meet unrealistic goals; the main contributors toward global warming (U.S. and China) are not even committed to the platform.  Therefore Canada has taken the following steps on the Federal level to develop policies that stress the importance in climate change:

·         Research and assess renewable energy options and best practices
·         Advocate for national renewable energy and energy efficiency (RE/EE) strategies, and for the establishment of national body(ies) to coordinate and lead RE/EE by: 
·         participating in consultation processes, meetings and working groups on renewable fuels, green electricity and energy efficiency
·         working in partnerships such as the Canadian Renewable Energy Alliance (CanREA)
·         providing accurate information to Canadians on renewable energy to allow voters to make informed choices on energy issues
·         Develop model renewable energy and energy efficiency strategies that demonstrate feasible options for transitioning to a renewable energy economy
·         Encourage federal and provincial cooperation on renewable energy strategies and initiatives
·         Advance Canada’s role in working with other nations to maximize investment and support for renewable energy in developing countries, which will help improve access to services and move countries beyond an unstable, unhealthy and inequitable reliance on fossil fuels.

Canada's Federal Policy initiative shows a sense of their dedication towards mitigating climate change when they state that "Investing and supporting Canada’s renewable energy industries today will help create new jobs, ensure Canada is a competitive leader in the world’s future energy markets, and provide a reliable and secure source of energy for Canadian families. Increasing our use of renewable energy is also an important climate change strategy for Canada because it reduces our reliance on coal, oil and gas, which produce greenhouse gas pollutants that are fuelling global warming." (Retrieved  from <http://www.pembina.org/re/work/federal-policy> )

The pie chart below shows the different renewable resources Canada has had since 2010 and hope to have by 2035:



"The Government is committed to reducing total GHG emissions by 17% from 2005 levels by 2020. Canada is also committed to the goal of having 90% of  electricity provided by non-emitting sources such as hydro, nuclear, clean coal or wind power by 2020" (Retrieved from <http://www.ieahev.org/by-country/canada/> )  This image shows the variety of resources it has for electricity by region:

I personally believe that it is every countries moral duty to mitigate and adapt to climate change in any respective way they can. Especially Canada because they, like the U.S., India, and China are the world's top C02 producers and emitters.  I agree with Canada's decision to withdraw from the Kyoto Protocol and work toward a real platform that will involve the top C02 emitters first and follow a uniform process for collectively mitigating climate change on a global scale.  Yes, every country has to try their best to reduce their emissions but there should be a uniform process or platform for all to follow which would push policy towards a real change in the earth's climate.

Impacts of Climate Change

The overall assessment of the projected climate change for North America by the IPCC, states specifically that the entire continent of North America is  "very likely to warm during this century, and the annual mean warming is likely to exceed the global mean warming in most areas. In northern regions, warming is likely to be largest in winter, and in the southwest USA largest in summer. The lowest winter temperatures are likely to increase more than the average winter temperature in northern North America, and the highest summer temperatures are likely to increase more than the average summer temperature in the southwest USA." (IPCC, 2013).  The part that I found most interesting was that most of the warming in the northern parts like Canada will increase more during the winter than in the summer.  I actually thought it would be the exact opposite.  The key factors of why this is happening is stated in section 11.5.1, where it says that "Central and northern regions of North America are under the influence of mid-latitude cyclones. Projections by AOGCMs (Chapter 10) generally indicate a slight poleward shift in storm tracks, an increase in the number of strong cyclones but a reduction in medium-strength cyclones over Canada and poleward of 70°N. Consequent with the projected warming, the atmospheric moisture transport and convergence is projected to increase, resulting in a widespread increase in annual precipitation over most of the continent except the south and south-western part of the USA and over Mexico" (IPCC, 2013).  This shows that the overall precipitation will increase as well.  Thus with increased temperatures and precipitation will happen mainly in the upper northern regions of North America, like Canada.  The middle region, or America, will have the opposite reactions but seem to be in harmony with the Keeling Curve. Just like the Keeling Curve suggests the entire continent of North America (along with the entire globe) will experience a clear and evident warming.

The IPCC's report on Working Group II: Impacts, Adaptation and Vulnerability show some extremely disheartening information with regards to North America as a continent.   It states that "Warming in western mountains is projected to cause decreased snowpack, more winter flooding, and reduced summer flows, exacerbating competition for over-allocated water resources. *** D [14.4B14.2].  Disturbances from pests, diseases and fire are projected to have increasing impacts on forests, with an extended period of high fire risk and large increases in area burned. *** N [14.4B14.1].  Moderate climate change in the early decades of the century is projected to increase aggregate yields of rain-fed agriculture by 5-20%, but with important variability among regions. Major challenges are projected for crops that are near the warm end of their suitable range or which depend on highly utilised water resources. ** D [14.4]" (IPCC, 2013).  In Colorado, which is a very mountainous region, we are already experiencing abnormal wild-fires that seem to be uncontrollable. As well as the insect problem mentioned in the above quote.  It only makes since that the increased heat caused a "decreased snowpack" and is exhausting our natural water resources.  This link http://www.nbcnews.com/video/nightly-news/52291488/#52291488 will take you to a video on NBC Nightly News with Brian Williams, which is in perfect harmony with the information collected by the IPCC.  One of NBC's reporters stated that the extreme wildfires in the U.S. are also experiencing "too many insects and not enough water" (NBC, 2013). Apparently, the wildfires now have spread to over six western states! It was also stated that in Canada they are experiencing historic flooding and rain. I wondered if this also has to do with the decreased snowpack, and it seems that it does, along with several problems in our Polar region.  The IPCC report states that "In the Polar Regions, the main projected biophysical effects are reductions in thickness and extent of glaciers and ice sheets, and changes in natural ecosystems with detrimental effects on many organisms including migratory birds, mammals and higher predators. In the Arctic, additional impacts include reductions in the extent of sea ice and permafrost, increased coastal erosion, and an increase in the depth of permafrost seasonal thawing. ** D [15.315.415.2] (IPCC, 2013). So, overall it looks like it is the result of too much heat; which is causing a cyclical effect causing everything in our polar regions to melt slowly.  Many cities like Calgary have been declared a disaster zone and evacuation is mandatory.  This is quite surprising because I have not heard about the massive floods in Canada until creating this blog.  This could be in part because the U.S. lame stream media decided to take global warming off of their main agenda, as it would eventually affect the profits of their major shareholders' oil reliant companies.
  
The Executive Summary for North America by the IPCC explains the overall situation of climate change for the entire continent.  The Summary made a very profound statement when it mentioned that “‘Mainstreaming’ climate change issues into decision making are a key prerequisite for sustainability".  Personally, I believe this is the biggest threat to the overall continent because the policies that Canada, America, and South America operate by cause a perpetual system of environmental destruction.  The policies used to back the oil based companies are so detrimental to our future generations that if there are not immediate changes implemented to find alternative sources of energy the damage will be non-repairable, as it already is.  The visual image that comes to mind is the Melting Permafrost Feedback chart, as well as the Ice Albedo Feedback chart from Module 1, section 5.  These two climate feedbacks will  have  a significant role in the overall climate change of Canada, along with prehistoric policies; the melting permafrost seems to post the biggest threat to Canada's climate.




The slide above shows the cycle of increased temperature causes the permafrost to melt, thus causing methane to be released and atmospheric concentrations increase, which then enhance the overall greenhouse effect.  This is what is known as a positive feedback, but will have an extremely negative outcome for Canada.  Just like in Colorado, as large glaciers (or permafrost) melts it will cause the flooding we now see in Canada, not to mention the increased greenhouse gas effect that is not the positive greenhouse gas effect.  However, based on research found at the National Science Foundations website (www.nsf.gov), it seems that sea level rise will significantly impact Canada and North America as a whole more than other continents due to the melting ice sheet in Greenland.  The NSF stated this in an article published in May of 2009 "The melting of the Greenland Ice Sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax and other cities in the northeastern United States and Canada, according to new research."  They go on to say "A study in Nature Geoscience in March warned that warmer water temperatures could shift ocean currents in a way that would raise sea levels off the Northeast by about 20 centimeters (8 inches) more than the average global sea level rise that is expected with global warming. But it did not include the additional impact of Greenland ice, which at moderate to high melt rates would further accelerate changes in ocean circulation and drive an additional 10 to 30 centimeters (4 to 12 inches) of water toward northeastern North America on top of the average global rise." (NSF, 2009).

 Four to Twelve inches of water will definitely prove to be one of the most serious problem's North America will have to contend with.   The NSF also points out how this rise in sea level will affect the northward Atlantic conveyor belt “The northeast coast of North America is especially vulnerable to the effects of Greenland ice melt because of the way the meridional overturning circulation acts like a conveyer belt transporting water through the Atlantic Ocean. The circulation carries warm Atlantic water from the tropics to the north, where it cools and descends to create a dense layer of cold water. As a result, sea level is currently about 71 centimeters (28 inches) lower in the North Atlantic than the North Pacific, which lacks such a dense layer. If the melting of the Greenland Ice Sheet were to increase by 3 percent or 7 percent yearly, the additional fresh water could partially disrupt the northward conveyor belt. This would reduce the accumulation of deep, dense water. Instead, the deep water would be slightly warmer, expanding and elevating the surface across portions of the north Atlantic."(NSF, 2009).  This is eerily similar to the Younger Dryas period mentioned in Module 4.  The large concentration of freshwater caused a weak thermohaline circulation that completely stopped the ocean circulation casing a rapid cooling like the professor mentioned in the movie "The Day After Tomorrow" minus the Hollywood added Tsunami.  I see the connection here and I sincerely hope that the melting of Greenland does not cause a ice age type cooling like the Younger Dryas.  Although with all this increased warmth, I wonder if this rapid cooling would somehow create some sort of counter balance.  I am not sure how that would work, but it seems extremely daunting to say the least.

Canada and the World’s top CO2 Emission Contributors to Climate Change


This graph is called the Keeling curve and measures the Carbon Dioxide (CO2) concentration in the atmosphere. Concentrations are a combination of CO2 emissions and natural CO2  that the earth creates.

Reference:





This graph shows the "Total Fossil Fuel Emissions" produced by the world's top developed countries and shows why they are the largest contributors to CO2 emissions on a global scale.

Reference:




The emission sources show a dramatic increase right around the latter part of the Industrial Revolution, or 1920-30's.  This matches the U.S. trend that shows when an economy and population grows by use of oil, so does the carbon emission output. This is the direct result of taking the carbon stored in the oil and releasing it right back into our troposphere by burning fossil fuels (Keeling curve).  This really is a global trend because like the movie "Crude - the incredible journey of oil" showed that we can now measure in the ice, the carbon "footprint" dating back hundreds of thousands of years.  This carbon emission output in Canada is just more evidence that verifies that the planet, as a whole, started to increase its carbon dioxide concentration during the Industrial Revolution (discovery of oil) to record amounts that the earth has never experienced since its inception!  I don't know if this increase in carbon can be considered "unusual" because the entire world has such a pervasive increase that it seems to be the norm now, unfortunately…


Canada began emitting significant amounts of  COaround the same time that all of the developing countries started to increase - the Industrial Revolution and discovery of oil.  This increase by the developing countries, such as Canada, China, Russia, and the U.S. was so dramatic that a treaty was formed named the
The Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) (Retrieved from <https://en.wikipedia.org/wiki/Kyoto_Protocol> ).  This treaty does not have much power in enforcing its limitations but it is supposed to be a treaty that " sets binding obligations on industrialized countries to reduce emissions of greenhouse gases. The UNFCCC is an environmental treaty with the goal of preventing "dangerous" anthropogenic (i.e., human-induced) interference of the climate system.[10] There are 192 parties to the convention, including 191 states (all UN members, except Andorra, Canada, South Sudan and the United States) and the European Union.[11] The United States signed but did not ratify the Protocol and Canada withdrew from it in 2011.[2] The Protocol was adopted by Parties to the UNFCCC in 1997, and entered into force in 2005.[6]"

Canada withdrew from the treaty in 2011.  The reason for their withdrawal, according to Peter Kent - Environment Minister to Canada was because the worlds largest emitters are not involved so it is null and void, and would cost Canada billions of dollars to meet it's requirements.  In this link, Kent shows that they will withdraw from the Kyoto Protocol because the "world's largest CO2 emitters, the U.S. (#1) and China (#2) are not apart of the treaty and therefore, cannot work" ( http://www.guardian.co.uk/environment/2011/dec/13/canada-withdrawal-kyoto-protocol) .  It seems that the Bush administration refused to join because China wouldn't join, and China wouldn't join because the U.S. refused to join, so it created a stalemate.  It was also said in the above article, that even if the countries involved did not meet the conditions there are no circumstances that the countries would suffer from in the treaty.  These treaties that only happened recently seem to be purely for publicity and have no impact on reducing the CO2  levels on our planet. 

    1. Compare your most recent per capita (per person) value to that of the United States citizen, which is 4.9 metric tons of carbon.  (Take your value and divide it by 4.9 to figure out your percentage of emissions compared to the US emissions.)  Is your value higher or lower than the US value?  Why?

According to the CDIAC, the " Per capita CO2 emissions from Canada stand at 4.46 metric tons of carbon per person placing Canada among the highest of the major fossil-fuel CO2-emitting nations."  So if I take 4.46 per person and divide it by 4.9, it would equal 0.9102 (but I am not sure what that means and if it is higher). However the CDIAC said that Canada is the highest major fossil-fuel nations.  This is conflicting with other information I saw, but the CDIAC site seem to be the most up to date.

The reason why is stated by the CDIAC as being a result of  "The post-1980 drop was comparable to that observed in the United States, and the pattern from 1980 to 1987 was erratic but essentially at a constant level. After 1987, annual fossil-fuel CO2 releases increased irregularly peaking in 2005 at 153 million metric tons of carbon. The 2008 estimate, approximately 148 million metric tons of carbon, represents a 3.3% decline from the 2005 peak value. In 2008, liquid fuels contributed 46.7% of total fossil-fuel CO2 emissions, natural gas contributed 32.4%, and coal contributed 18.8%." (Pasted from <http://cdiac.ornl.gov/trends/emis/tre_can.html> )


  1. Visit http://cdiac.ornl.gov/trends/emis/top2008.cap and find your country’s rank based on per capita CO2 emissions.  What is the rank?  What is the rank of the United States? (C.) How do you, as the blog author, feel about your country’s rank?

According to the site above Canada is ranked #15 and the United States is ranked #`12, stating the U.S. has 4.9 metrics of carbon and Canada has 4.46, which is less.  As the author, I feel good that my country has a less metric output of carbon per person than the U.S., but as a citizen of the U.S. this does not feel good at all, but unfortunately this is not a shock.

 "12    UNITED STATES OF AMERICA                               4.90
  13    SAUDI ARABIA                                           4.69
  14    OMAN                                                   4.48
  15    CANADA                                                 4.46"


                                                                ** Sidebar**

This website is amazing! It is called http://www.breathingearth.net/ and if you click on your country you can see the amount of CO2 being emitted in real time, as well as the actual growth and decline of the human population; statistically in real time.  It is quite daunting information!  As I am writing this 870 people were born in the world and 389 have died, these number consistently change by the second. This also is a contributing factor to the  CO2 emissions produced by each country.

  1. Using the “Total Fossil Fuel Emissions by Country” graph that you created,
    1. Discuss how your country compares to other countries on the graph.  Any surprising results?  Any historic events that can account for them? 

Canada seems to be dramatically lower in Fossil fuel emissions than the U.S. and China, particularly during the beginning years of 1900 up until the early 2000's.  That is surprisingly different than the CO2 Emissions from Canada graph retrieved from <http://cdiac.ornl.gov/trends/emis/can.html> , because it stated that Canada was amonst the nations with the highest CO2 emissions.

  1. Which country was the biggest emitter of carbon dioxide in 2008 (the most recent data available)?

China definitely surpassed every other country in 2008.  Most likely due to their lack of regulation on fossil fuel emissions.

  1. If the US has 312,000,000 people and China has 1,338,000,000 people, on a per capita basis, who is more at fault for emitting CO2, an American or a Chinese citizen? 

I think the fault should be more directed towards the governments and their lack of regulation towards CO2 emissions, mainly because the citizens, generally, will do what the governments tell them to do. If there are no limits then it is inevitable for the number to increase, regardless of the population.

  1. Now, let’s consider a country’s cumulative contribution to climate change, which can be seen visually by viewing the area under the curve for each country.  .  Record this value for each country here.  Remember, these are in thousand metric tons carbon.  Cumulatively, which country is responsible for the most CO2 emissions? 

Canada = 7,110,992
U.S. = 9,395,610
China = 31,793,584
India = 9,182,205
Kenya = 80,124
Italy = 5,431,571

By looking at the numbers above, China dwarfs every other country with a total of 31,793,584 thousand metric tons of carbon!!

  1. Take China’s total CO2 emissions number that you just calculated and divide it by the number for the U.S.  (China/US=?)  Now do the same for India.  State your results in a meaningful way to compare the countries.

(China)31793584 divided by  ( U.S.)9395610 = 3.3839 

(China) 31793584 divided by  (India) 9182205 = 3.4625

Since the total of metric tons of carbon are similar in the U.S. and India, it seems the outcome is the same.  I have to be honest here thought, I am not really sure what that outcome or the results mean though…?



  1. Let’s note that carbon emissions are different than carbon dioxide concentrations!  Compare your first graph, the Keeling Curve, to this graph, the global emissions of carbon: Note the different years on both graphs.  Are the two graphs similar in shape?  Discuss how emissions are different than concentrations.  (Think back to the carbon cycle lecture in class). 
     

Comparing the Keeling curve graph to the Global emissions of Carbon graph, shows many similarities and a couple differences.  I noticed that the concentration levels are measured in ppm's and the emission levels are measured in metric tons of carbon.  The years are different, the Keeling curve dates back to 1950 and the Global Emissions graph dates back to 1750.  The long term trend is extremely similar. It shows how during the beginning of the 1900's the amount of emission's added by mankind is global and the concentration as a result increased dramatically as well.  I found this great article below from www.skepticalscience.com that explained the difference of concentration and emissions in an easy to understand format:
What the science says...
When CO2 emissions are compared directly to CO2 levels, there is a strong correlation in the long term trends. This is independently confirmed by carbon isotopes which find the falling ratio of C13/C12 correlates well with fossil fuel emissions.
To directly compare CO2 emissions to atmospheric CO2 levels, both sets of data can be converted to gigatonnes of CO2. The CO2 emissions data is typically expressed in gigatonnes carbon (GtC). One gigatonne is equal to one billion tonnes. This means they've only included the carbon element of the carbon dioxide molecule. The atomic mass of carbon is 12, while the atomic mass of CO2 is 44. Therefore, to convert from gigatonnes carbon to gigatonnes of carbon dioxide, you simply multiply 44 over 12. In other words, 1 gigatonne of carbon equals 3.67 gigatonnes of carbon dioxide.
Atmospheric CO2 levels are expressed in parts per million by volume (ppm). To convert from ppm to gigatonne of carbon, the conversion tables of the Carbon Dioxide Information Analysis Center advise that 1 part per million of atmospheric CO2 is equivalent to 2.13 Gigatonnes Carbon. Using our 44 over 12 rule, this means 1ppm = 7.81 Gigatonnes ofCarbon Dioxide. Thus the two time series can both be plotted together expressed as gigatonnes of carbon dioxide:
It isn't too much of a stretch to imagine the amount of CO2 we put into the atmospheremight have a causality link with the amount of CO2 that remains in the atmosphere. Nevertheless, further confirmation comes by analysing the types of CO2 found in the air. The carbon atom has several different isotopes (eg - different number of neutrons). Carbon 12 has 6 neutrons, carbon 13 has 7 neutrons. Plants have a lower C13/C12 ratio than in the atmosphere. If rising atmospheric CO2 comes fossil fuels, the C13/C12 should be falling. Indeed this is what is occuring (Ghosh 2003) and the trend correlates with thetrend in global emissions" (Retrieved  from <http://www.skepticalscience.com/CO2-emissions-correlation-with-CO2-concentration.htm> )

I understood that to mean that concentrations are a combination of both CO2 emissions and natural CO2 the earth produces naturally.  The CO2 emissions that mankind emits into the air are measured differently, but on a global scale, and in the long term; it is no doubt increasing as a result.  However, the concentration does not change if the emissions change, it is still there. That is kind of daunting  it shows , well maybe just for humans. The only ones  stand to be affected are the ones causing it - humans, accept the animals will have to suffer as well. However, in terms of the earth, it will just turn this excess amount of CO2 right back into oil, humans included. Then it will convert back to it's normal cycle just like it did after every ice age and after the dinosaurs were extinct.
