The ‘Greenhouse Effect’ discovered in 1824 by Joseph Fourier is what keeps the earth from being a frozen ball in space. Without greenhouse gases (GHG’s) the temperature of earth would be below freezing and incapable of supporting life as we know it. It is precisely because GHG’s other than water are such a tiny fraction of the atmosphere that adding a little more can have a large effect on the climate system of earth.

Sea levels are rising everywhere, but in some areas they are rising quicker than others, bringing increased dangers of flooding. A new satellite — Jason 2 — has been launched to continue work to monitor the situation, providing valuable information for scientists trying to understand how ocean levels fit into the climate change puzzle.

“Climate Change and The Global Ocean” is the first episode in the six-part series “Tides of Change”, exploring amazing NASA ocean science to celebrate Earth Science Week 2009.

For years, scientists have studied the world’s oceans by sending out ships and divers, deploying data-gathering buoys, and by taking aerial measurements from planes. But one of the better ways to understand oceans is to gain an even broader perspective – the view from space. NASA’s Earth observing satellites do more than just take pictures of our planet. High-tech sensors gather data, including ocean surface temperature, surface winds, sea level, circulation, and even marine life. Information the satellites obtain help us understand the complex interactions driving the world’s oceans today – and gain valuable insight into how the impacts of climate change on oceans might affect us on dry land.

Nobel laureate Paul Crutzen proposes a possible escape route from nearly out-of-control global warming. He explores the possibility of releasing light-reflecting sulfur particles into the upper atmosphere, which would redirect heat back into space, cooling the global climate.
