Climate: bad news. According to the latest report of the Intergovernmental Panel on Climate Change (IPCC) published in August and approved by 195 governments, scientists detect changes everywhere on the planet. Many of these changes are unprecedented in thousands of years, and some of those that are already taking place – such as the continuous rise in sea level – won’t be reversible for hundreds or thousands of years. However, scientists point out, strong and steady reductions in carbon dioxide (CO2) and other greenhouse gas emissions could limit them, with rapid benefits for air quality, while to see global temperatures stabilize, it could take 20- 30 years.
