In her column, MLA Michelle Mungall spoke of the need to reduce CO2 emissions, which means reduced fossil fuel consumption, in order to slow and then stop the human caused climate change we now experience.
In his letter, Robert Leggett suggested that in the natural cycle of global warming and cooling that the warming happens hundreds to thousands of years before any CO2 increases.
When searching the Internet for additional information, it became obvious that caution is needed when looking for credible data.
The work done by climate scientists, whose work is peer reviewed, tends to produce data different from groups such as the Heartland Institute. The former finds that the natural heating – cooling cycle has been interrupted by increased CO2 in the atmosphere and that there is a close cause and effect relation between increased CO2 levels and global temperature increases.
For all of the 195 nations developing an agreement at the Paris climate talks, there seems to be a shared concern that the use of carbon based energy forms need to be reduced and then eliminated. Elizabeth May, commenting on CBC’s The House, said if you start examining the costs, what are the costs of doing nothing? The need for transition is clear. Hopefully the political will is too.
