Air pollution is ‘biggest environmental health risk’ in Europe

Air pollution is now “the biggest environmental risk” to public health in Europe but governments are failing to adequately deal with the crisis, the EU Court of Auditors has found. Europe’s air pollution limits are “much weaker” than WHO guidelines – and most EU countries do not comply with them anyway, according to the damning […]

Build walls on seafloor to stop glaciers melting, scientists say

Building walls on the seafloor may become the next frontier of climate science, as engineers seek novel ways to hold back the sea level rises predicted to result from global warming. By erecting barriers of rock and sand, researchers believe they could halt the slide of undersea glaciers as they disintegrate into the deep. It […]

No Ecosystem on Earth Is Safe From Climate Change

If climate change continues unabated, nearly every ecosystem on the planet would alter dramatically, to the point of becoming an entirely new biome, according to a new paper written by 42 scientists from around the world. They warn that the changes of the next 200 years could equal—and may likely exceed—those seen over the 10,000 […]

How to eat well – and save the planet

Switching to a healthier diet can reduce an individual’s water footprint by as much as 55%. According to new research, turning vegetarian has the biggest impact, but even cutting down on meat gives a saving of at least 10%. Shifting to a healthy diet is a “win-win situation”, say researchers. Citizens will be healthier and […]

Canada’s high Arctic glaciers at risk of disappearing completely, study finds

Hundreds of glaciers in Canada’s high Arctic are shrinking and many are at risk of disappearing completely, an unprecedented inventory of glaciers in the country’s northernmost island has revealed. Using satellite imagery, researchers catalogued more than 1,700 glaciers in northern Ellesmere Island and traced how they had changed between 1999 and 2015. The results offered […]

Weatherwatch: Antarctica proves to be even colder than previously thought

Where is the coldest place on Earth? Antarctica; yes, but where exactly? On 23 July 1983, the thermometer at the Vostok station, high on the East Antarctic plateau on recorded the lowest measured air temperature on Earth: a frigid -89.2C. But, in recent years, satellite data has revealed it can get even colder. Measurements beamed […]

Rising ocean waters from global warming could cost trillions of dollars

Ocean waters are rising because of global warming. They are rising for two reasons. First, and perhaps most obvious, ice is melting. There is a tremendous amount of ice locked away in Greenland, Antarctica, and in glaciers. As the world warms, that ice melts and the liquid water flows to the oceans. The other reason […]

Baltic Sea oxygen levels at ‘1,500-year low due to human activity’

The coastal waters of the Baltic have been starved of oxygen to a level unseen in at least 1,500 years largely as a result of modern human activity, scientists say. Nutrient run-off from agriculture and urban sewage are thought to be to blame. “Dead zones” – areas of sea, typically near the bottom, with a […]

Most of Europe’s rivers and lakes fail water quality tests – report

The vast majority of Europe’s rivers, lakes and estuaries have failed to meet minimum ecological standards for habitat degradation and pollution, according to a damning new report. Only 40% of surface water bodies surveyed by the European Environmental Agency (EEA) were found to be in a good ecological state, despite EU laws and biodiversity protocols. […]
