We must work together to slow climate change
Letter-writer John Work is correct in that the sun does power a planet’s climate system. However, its atmosphere also has a profound impact. For example, although Mercury is closer to the sun, Venus is hotter because its atmosphere is mostly carbon dioxide.
I encourage reading The Scientific Guide to Global Warming Skepticism. It’s available online and provides an excellent summary of lines of evidence that have led 200 science academies throughout the world, including the Royal Society of Canada, to conclude that climate change is human-caused.
Our common values like national security and concern for our children’s future should unify us on this issue. It just doesn’t make sense to make the long-term changes to the Earth’s physics and chemistry that we are making without looking at this closely together, across political divides, with open ears and open hearts. Let’s urge our politicians and business leaders to work together and find a path to slow climate change.
