We need to reduce emissions to keep our planet safe for future generations – the science is clear. However, it can be quite hard to get your head around how to do that. Here’s a very simple idea from writer and climate campaigner, Bill McKibben: keep fossil fuels in the ground. If we were to burn…
A new open access study in Science Advances concludes that a warming beyond the 2°C target would potentially lead to rates of sea-level rise dominated by ice loss from Antarctica, and continued CO2 emissions from fossil sources could cause additional tens of meters of sea level rise, over the next millennia and eventually ultimately eliminate the…
James Lovelock talks to David Freeman about his book A Rough Ride to the Future on 29 March 2014 at the FT Weekend Oxford Literary Festival at the Oxford Martin School. Independent scientist and futurist James Lovelock, originator of Gaia Theory, explores our future on the planet through two new, key ideas. The first is…
Researchers at The University of Texas at Austin have found that a well-known period of abrupt climate change 12000 years ago occurred rapidly in northern latitudes but much more gradually in equatorial regions, a discovery that could prove important for understanding and responding to future climate change. The research, published Sept. 2 in Nature Communications,…
This is climate change: Alaskan villagers struggle as island is chewed up by the sea In this town of 403 residents 83 miles above the Arctic Circle, beaches are disappearing, ice is melting, temperatures are rising, and the barrier reef Kivalina calls home gets smaller and smaller with every storm. There is no space left…
There are various signs in earth past which point at rapid climatic developments. Lovelock explains based on his modelling potential implications. White talked about ice core records which point to similar circumstances. More Abrupt Climate Change explained by Jim White, 12 Minutes excerpt (@AGU 2014)
2012: Professor James White reviews the basic science behind the Earth’s climate system and discusses how humans are impacting it and put the current climate situation into the context of natural variability. White is director of the Institute of Arctic and Alpine Research.
At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being “crime scene investigators,” these experts are more like “cold scene investigators.” Geoscientists like lab director Jim White work primarily with one raw material : ancient ice, in…

Milkweed plants from the chambers were fed to hundreds of monarch caterpillars this summer. Milkweed is a monarch caterpillar’s only food, satisfying its nutritional needs while providing an invaluable medicinal boost. The plant’s leaves contain a bitter toxin that helps the insects ward off predators and parasites. But previous work at U-M’s northern Michigan biological…
President Barack Obama challenged fellow world leaders in unusually blunt language Monday to act boldly on climate change or “condemn our children to a world they will no longer have the capacity to repair.” In a forceful address, Obama opened the “GLACIER” conference in Anchorage, Alaska, by declaring: “We are not moving fast enough. None…
GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the…
