Royal Society: An introduction to climate change in 60 seconds

Published on Dec 10, 2014: Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences. During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet…

ScienceCasts: Climate Change and the Yin-Yang of Polar Sea Ice


Arctic and Antarctic sea ice are both affected by climate change, but the two poles of Earth are behaving in intriguingly different ways.

Natural Gas versus Coal Power Plants: Greenhouse gas warming

Ken Caldeira: We had a paper come out comparing effects of natural gas versus coal plants, aimed at understanding how much methane leakage there could be from natural gas before it caused more near-term warming than coal. The answer depends on how efficient the different power plants are, but one thing that is clear is…

ScienceCasts: The Cloudy Future of Arctic Sea Ice

As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to find out how these developments will affect worldwide weather. NASA: Oct 15, 2014: Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place…

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

ClimateState interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and landslides)…

Arctic Sea Ice, Summer 2014 (NASA animation)

An animation of daily Arctic sea ice extent in summer 2014, from March 21, 2014 to Sept. 17, 2014 – when the ice appeared to reach it’s minimum extent for the year. It’s the sixth lowest minimum sea ice extent in the satellite era. The data was provided by the Japan Aerospace Exploration Agency from…
