Global warming is happening is '10 times faster than at any time in the Earth's history'

Daily Mail: American scientists claim the planet is undergoing one of the largest changes in climate in the past 65 million years. Climatologists at Stanford Woods Institute for the Environment have warned the likely rate of change over the next century will be at least 10 times quicker than any climate shift since the dinosaurs became extinct. If the trend continues at its current rapid pace, it will place significant stress on terrestrial ecosystems around the world, and many species will need to make...
Our Once And Future Oceans: Taking Lessons From Earth's Past

National Public Radio: One of the most powerful ways to figure out how the Earth will respond to all the carbon dioxide we're putting into the atmosphere is to look back into the planet's history. Paleontologists have spent a lot of time trying to understand a time, more than 50 million years ago, when the planet was much hotter than it is today. They're finding that the news isn't all bad when you take the long view. About 10 million years after the dinosaurs died out, the Earth suffered another huge ecological...

Tropical ecosystems regulate variations in Earths carbon dioxide levels

CSIRO: The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on average. This is the equivalent of 1/3 of the annual global emissions from the combustion of fossil fuels and deforestation together. Importantly, the NASA Earth Exchange (NEX) study results provide scientists with a new diagnostic...

Ocean sensor expands Earth's living color observation efforts
2013-07-25 19:03:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Remote sensing of ocean color is a currently well-established science that provides information about water composition and the depth of light penetration based on the ocean color, as seen from space. Ocean color satellites are part of an Earth observing system and, due to the importance of this system in understanding the state of the ocean and its evolution, the international scientific community has agreed to joint efforts to keep a constant constellation of ocean color satellites orbiting our...
