NOAA Earth scientists discuss their roles and responsibilities in sharing what they know about the climate system with the public.

“If the sea level goes up two or three feet along the coast of Maine in this century, that’s a very significant change.”  

“The fact is scientists really can’t predict at this time what the impacts will be on any particular species.”  

On September 12, the extent of sea ice in the Arctic reached the third lowest level ever recorded since satellite records began in 1979. Only 2007 and 2008 have had smaller ice extents than 2009.

As the ocean absorbs atmospheric carbon dioxide, the pH of the water drops. The more acidic water harms corals and other shell-building sea life.

Improved computer models help scientists understand Earth’s ocean.

Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.

Richard Feely discusses new findings about how increased carbon dioxide in the atmosphere is making the oceans more acidic, and how that will affect ocean ecosystems and the marine animals that inhabit them.

The Pacific-North American teleconnection pattern influences regional weather by affecting the strength and location of the East Asian jet stream, and subsequently, the weather it delivers to North America.
