Countries must work together on CO2 removal to avoid dangerous climate change

The team, from Imperial College London, the University of Girona, ETH Zürich and the University of Cambridge, say countries need to start working together now to make sure enough CO2 is removed in a fair and equitable way. Reaching these targets will require mitigation lowering the carbon dioxide (CO2) emitted through changes such as increased use of renewable energy sources, and removal of CO2 from the atmosphere through measures such as reforestation and carbon capture and storage.

Potentially fatal combinations of humidity and heat are emerging across the globe

Most everyone knows that humid heat is harder to handle than the “dry” kind. And recently, some scientists have projected that later in the century, in parts of the tropics and subtropics, warming climate could cause combined heat and humidity to reach levels rarely if ever experienced before by humans. Such conditions would ravage economies, and possibly even surpass the physiological limits of human survival.

First come floods, then flowers, then fire: the ‘benevolent dictator’ of Southern California’s climate

Over a century ago, the city of San Diego offered Charles Hatfield the equivalent of $250,000 in today’s money to rescue it from a drought that had depleted the Morena Reservoir, which provided its drinking water. Hatfield, who referred to himself as a “moisture accelerator,” had developed an early form of geoengineering mechanism that sent little puffs of a vaporized chemical solution skyward.
