Eemian sea level rise update: just 1.6-2.2m from Greenland – Antarctic ice sheet less stable than we think?

Last week we learned 5 percent of the Eemian sea level rise was thermal expansion of the oceans. Today we learn the slightly higher temperatures led Greenland to ‘only’ add an extra 1.6-2.2m. Do we fail to spot the Antarctic … Continue reading

Protected areas are too few and growth too slow to prevent biodiversity loss

The current global network of protected areas is quite extensive, covering 17 million square kilometers of land and 2 million square kilometers of oceans. But the more than 100,000 areas appear to be insufficient to halt global biodiversity loss, according … Continue reading

Until 2050 97% of population growth comes from less developed regions

This year we will hit 7 billion. But the big demography news is not just the net growth figure, but also the differentiation – where it takes places. A new Harvard study has sifted through the billions of unborn people … Continue reading

Soy protein – with isoflavones – helps training women slim faster

If you ignore bonus doses of saturated fat, dioxins, hormones and antibiotics, animal protein can be very nutritious. Too bad ‘from October 31’ there will be 7 billion of us – and science shows that many people can’t all be … Continue reading

The wildfire climate feedback, tundra´s case: megatonnes of extra CO2

Globally 2007 was one of the hottest years on record. In the Arctic it led to the thus far smallest sea ice extent. But that’s not the only thing unprecedented that happened in the far north. For the first time … Continue reading

Melting Arctic ice releases persistent organic pollutants

Global temperatures are rising and as a result icecaps are melting. But as a study in Nature Climate Change shows icecaps don’t just discharge water when they melt. They also release a gift from generations past in the form of … Continue reading

The forest fire feedback, Yellowstone’s case: ecosystem shift by 2050

Climate change could cause the forests of the world’s oldest national park, Yellowstone, in the Eastern Rocky Mountains, to shift to a gras and shrub ecosystem, US scientists warn. It could happen in four decades, and will likely not be … Continue reading
