If water is life, then Europeans are under mortal threat. That was the message in a nutshell transmitted today by the European Commission's scientific advisers at the Copernicus Climate Change Service. Drought conditions not seen in some places since the Renaissance are becoming the continent's new normal, with perilous knock-on effects for food security and supply chains in the European Union, the world's third-biggest economy. Water levels on European rivers have been shrinking now for six years, with farmland drying up and Alpine glaciers in retreat. Taken together, they're creating climate feedback loops. Hotter temperatures mean more glacial melting and evaporation; less rainfall and Alpine runoff reduce river flows; dried-out water basins and shriveled vegetation create fuel for wildfire. While heat and drought are also afflicting regions from Asia to East Africa, Europe is a climate change front-runner, warming at twice the rate as other inhabited continents, according to Copernicus. Last year was 1.4C (2.5F) warmer than normal and right on the cusp of the 1.5C temperature-increase limit that scientists have set to keep life more-or-less normal this century.

Bloomberg The European Union is looking to the skies for guidance to solve its climate conundrum, pouring billions of euros into new Earth observation space missions. The Copernicus program uses measurements from satellites, ships, aircraft and weather stations around the world for its monthly and seasonal forecasts. It's already the world's biggest provider of climate data. But while better predictions might help farmers choose to plant drought-resistant crop varieties, or engineers plan better irrigation, they don't blunt the economic pain of climate change when it happens. Like an unwelcome guest who refuses to leave, global warming has settled in to Europe and is here to stay. This is what adapting to a hotter Earth looks like. — Jonathan Tirone |
