Charting Irreversible Climate Change with Jason-3

Streamed live on Feb 12, 2015

As humans drive Earth’s climate into a new regime, it is critical to keep our fingers on the pulse of the planet. Sea level rise is both a stark reminder of our impact on the climate and its impact on us. The oceans capture over 90 percent of the heat trapped by greenhouse gases, expanding as they warm. They also collect water from melting glaciers and ice sheets, making sea level rise a doubly important indicator of global warming. Without adaptation, a 2-meter rise would displace 187 million people worldwide. Sea level will continue to rise, but how fast? Like its predecessors, Jason-3 will serve as our eyes on sea level rise. Measuring global sea level once every 10 days, it will chart out the global rise of the oceans–a rise that is unlikely to subside or reverse for generations. But Jason-3 will be more than a sentinel of climate change. It will also measure the tilt of the ocean surface providing oceanographers with information about ocean currents, measure wind and waves helping forecasters predict marine weather, and even find local warm spots that can intensify hurricanes.

From my chair, it looks like we can kiss our stable nurturing climate goodby. Humans have poked and prodded and perturbed our Earth systems to the breaking point, and these systems are now breaking. Business as usual guarantees an unstable climate and gut-wrenching consequences for all life on this planet.

The Guardian interviews Sir David Attenborough about the impact of climate change and population growth. The broadcaster and naturalist says scientists and environmentalists have been cautious of overstating the dangers of global warming, but recent evidence of melting polar caps shows the situation is worse than had been thought. He also discusses population growth and disappearing habitats.

Hot summers, wildfires and drought are anomalies no longer. They are the visible products of climate change, and more can be expected. One solution may appeal to conservatives

James Hansen: Extreme Heat Events Connected to Climate Change

PBS NewsHour

Published on Aug 4, 2012

Dr. James Hansen of NASA, says there is now enough evidence to connect global warming to some of the extreme weather events of the recent past. Hansen tells the Newshour that there is now a 1 in 10 chance of extreme heat events like the 2010 Texas/ Oklahoma droughts, the 2010 heat wave in Russia and possibly even the heat wave scorching the Midwest in 2012.
