The Earth’s climate, it seems, isn’t listening to the politicians that are insisting it’s not warming. The temperature continues to rise incrementally, and the globe’s large glaciers—giant vaults of stored water—continue to melt, releasing into the oceans. The global sea level, due to thermal expansion and glacial melting, continues to rise, building up a head of steam like a train …
The ice sheet covering Greenland is four times bigger than California — and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. Today, sea levels are rising and the melting of Greenland is a major contributor. Understanding how fast this melting might proceed is a pressing question for policymakers and coastal …
The global warming crisis seems to get worse and worse, faster and faster. Now, Antarctica is in the spotlight with brand-new shocking research of a spine-chilling development. The whole of Antarctica, if melted in its entirety, equates to a sea level rise of 200’, but that will not happen during current lifetimes. It’s too big and would require way too …
Scientists show how different the world would be without a sprinkling of the wind-borne African dust that fertilises oceans and forests. LONDON, 3 December, 2016 − Climate scientists have identified Africa’s single biggest export – the wind-borne dust that fertilises the Amazon forests, nourishes life in the Atlantic ocean and softens the noonday blaze of the sun. And they have …
LONDON, 21 May, 2016 – One of Antarctica’s great glaciers could become unstable if global warming continues at the present pace. As warm seas wash the ice shelf, the land-based mass of ice could begin to retreat, cross a critical threshold in the present century and then withdraw 300 kilometres inland. In the course of doing so it would spill …
An interesting question is, what are you waiting for? Global warming is the biggest problem we’ve ever faced as a civilisation — certainly you want to act to slow it down, but perhaps you’ve been waiting for just the right moment. The moment when, oh, marine biologists across the Pacific begin weeping in their scuba masks as they dive on reefs …
A new study from climate scientists Robert DeConto at the University of Massachusetts Amherst and David Pollard at Pennsylvania State University suggests that the most recent estimates by the Intergovernmental Panel on Climate Change for future sea-level rise over the next 100 years could be too low by almost a factor of two. Details appear in the current issue of Nature. …
Sea-level rise may be the most predictable outcome of climate change. Expanding warmer waters and melting land ice both contribute to flooding – and scientists agree that we are locked into sea-level rise for centuries to come. The question is not if we will retreat from the coast, but when. Still, the rush to develop the coast occurs at a maddening pace. …
Greenhouse gases could tip the Earth – or at least a planet like Earth, orbiting a star very like the Sun – into a runaway greenhouse effect, according to new research. The new hothouse planet would become increasingly steamy, and then start to lose its oceans to interplanetary space. Over time, it would become completely dry, stay at a temperature …
Scientists’ reports about global warming are becoming more and more pessimistic. Will rising sea levels, drought, crop failure and water wars become so severe that humanity’s existence itself is threatened? Peter Phillips and Julie Andrzejewski speak first with David Ray Griffin, author of the new book, “Unprecedented.” Then Dahr Jamail, climate writer at Truthout, joins the discussion.
