It’s a vexing problem that a growing number of people around the world have had to cope with over the last two decades, as climate change fuels hotter, bigger fires that destroy forested catchments and consume towns and their water systems, engineers and scientists said.

Renewable Energy’s Booming, But Still Falling Far Short of Climate Goals

Renewable energy capacity quadrupled worldwide over the past 10 years, with an estimated $2.6 trillion invested in its growth, a new report from the United Nations Environment Programme shows.

This Summer’s Heat Waves Could Be The Strongest Climate Signal Yet

Earth’s global warming fever spiked to deadly new highs across the Northern Hemisphere this summer, and we’re feeling the results—extreme heat is now blamed for hundreds of deaths, droughts threaten food supplies, wildfires have raced through neighborhoods in the western United States, Greece and as far north as the Arctic Circle. At sea, record and near-record warm oceans have sent soggy masses of air surging landward, fueling extreme rainfall and flooding in Japan and the eastern U.S. In Europe, the Baltic Sea is so warm that potentially toxic blue-green algae is spreading across its surface.
