The recent warming has been more pronounced in the Arctic Eurasia than in many other regions on our planet, but argues that only one out of 109 temperature records from this region exhibits a significant warming trend.

Cato Institute scholar Indur Goklany offers a dramatically different assessment in Humanity Unbound: How Fossil Fuels Saved Humanity from Nature and Nature from Humanity.

Physicians treating patients with respiratory symptoms look for underlying causes or aggravators, and that includes exposure to air pollution. If that pollution involves particulate matter – also known as soot – their concerns intensify, because of its well-known [...]
