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.  

Along coasts, people are waking up to the need for adaptation to climate change. This article points the way to information for getting started.

Across the contiguous United States, more than a third of the land has an above-average risk of flooding this spring, according to an announcement issued on March 15 by NOAA’s National Weather Service.

Global climate models project that near the end of the 21st century, average surface temperature over most of Earth’s surface will be several degrees warmer than today, mainly due to rising levels of greenhouse gases in the atmosphere.

Almost two months after a devastating earthquake rocked Haiti, nearly half a million people there are displaced from their homes, and a million more are living without proper shelter. What climate-related risks will they face in the coming months?

From the African savanna to North America’s boreal forests, NOAA’s CarbonTracker tool provides insight into what natural and human processes affect the uptake, release, and transport of carbon dioxide in Earth’s lower atmosphere.

NOAA researchers have built a "time machine" for weather that provides detailed snapshots of the global atmosphere from 1891 to 2008. The system's ability to "hindcast" past weather events is emerging as a powerful new tool for detecting and quantifying climate change.

Many of the Northwestern Hawaiian islands where sea turtles nest have low, flat coastal plains. They are already vulnerable to storm surges, and they could be totally inundated as sea level rises.
