In 2010, global temperatures were marked by near-record warmth and strong natural variability. This is the first in a series of posts highlighting findings from the "State of the Climate in 2010" report.
Computer climate models help scientists such as Dave Dewitt predict the life cycles of individual El Niño or La Niña events and their effects on weather patterns throughout the world. While the accuracy of these models continues to improve, they still have limitations.
Will climate change affect frequency or intensity of El Niño and La Niña? There is still little consensus among scientists on this, explains the International Research Institute for Climate and Society’s Lisa Goddard.
Each of the last three decades was warmer than all earlier decades in the instrumental record, and each set a new and statistically significant record, culminating in the 2000s, which was the warmest decade of all.
This report presents a comprehensive appraisal of Earth’s climate in 2009, and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.
At the highest point atop the Greenland Ice Sheet, Matthew Shupe and his colleagues are installing a suite of climate and weather instruments. Their goal is to better understand the role of clouds in the rapid warming observed across the Arctic region.
Will ocean currents carry oil and byproducts from the Deepwater Horizon wellhead beyond the Gulf of Mexico and out into the open Atlantic Ocean? Climate data and computer models help scientists predict how and where.
On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.
The United States' 28 National Estuarine Research Reserves (NERR) are experiencing negative effects of human and climate-related stressors, according to a new report from NOAA's National Ocean Service. This is the first national-scale climate sensitivity analysis of estuaries to help coastal managers protect the health of estuaries.
Introducing the Local Climate Analysis Tool (LCAT)
July 15, 2013
NOAA unveiled this powerful new tool in July 2013 to help users produce data-driven answers to climate-related questions. The tool helps users link local weather and water events to signals in the climate system; understand how global climate change contributes to local climate trends; and explore how climate variability contributes to local impacts. Registration is required to use LCAT.
