Greenhouse gases continue climbing; 2012 a record year

Greenhouse gases continue climbing; 2012 a record year

NOAA’s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many heat-trapping gases like carbon dioxide and methane, shows 2012 continued the steady upward trend that began with the Industrial Revolution of the 1880s.  Last year, CO2 at the peak of its cycle reached 400 ppm for one month at all eight Arctic sites for the first time.

Clearing up confusion on future of Colorado River flows

Clearing up confusion on future of Colorado River flows

The Colorado River provides water for more than 30 million people. Increasing demand for that water combined with reduced flow and the looming threat of climate change have prompted concern about how to manage the basin’s water in coming decades. NOAA-funded researchers at the University of Washington and co-authors at eight institutions across the West aim to explain this wide range, and provide policymakers and the public with a framework for comparison.

New NOAA study in North Carolina may improve forecasting, lead times for dangerous storms

New NOAA study in North Carolina may improve forecasting, lead times for dangerous storms

This month, NOAA launched a 1½-year long pilot study in North Carolina to improve understanding and forecasting of dangerous storms that can lead to flooding and economic losses. From the coastline to the mountains, state-of-the-art NOAA instrumentation is being set up in numerous locations across the state that may improve forecasting and lead-time for tropical storms and summertime thunderstorms.

Scientists working to crack key air quality and climate mysteries in U.S. Southeast

Scientists working to crack key air quality and climate mysteries in U.S. Southeast

Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.

New study finds direct evidence of summer climate change

New study finds direct evidence of summer climate change

In many parts of the world, summers just aren't what they were a generation or two ago. Summer climates in some places are changing—mostly, but not always, warming—according to a new analysis of 90 years of observational data.

New NOAA study suggests Great Plains may not suffer semi-permanent Dust Bowl as climate changes

New NOAA study suggests Great Plains may not suffer semi-permanent Dust Bowl as climate changes

A new NOAA study explores the reasons behind diverging views on future Great Plains drought. The good news is that it will probably not be as dire as some earlier studies suggest.

NOAA, National Archives team up with citizen-scientists to reconstruct historical climate of the Arctic

NOAA, National Archives team up with citizen-scientists to reconstruct historical climate of the Arctic

Before satellites, weather data transmitters, or computers, there were the ship's logs of Arctic sea voyages. A new crowdsourcing effort could make the weather data from these ship logs available to climate scientists worldwide.

Scientists show climate patterns may influence extreme U.S. tornado seasons

Scientists show climate patterns may influence extreme U.S. tornado seasons

NOAA and university researchers believe they have found a climate signal related to a specific phase of the El Niño-Southern Oscillation that could be linked to, and possibly serve as a predictor of, massive tornado outbreaks.

NOAA, partners: Earth’s oceans and ecosystems still absorbing about half the greenhouse gases emitted by people

NOAA, partners: Earth’s oceans and ecosystems still absorbing about half the greenhouse gases emitted by people

Earth’s oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study by University of Colorado and NOAA scientists published today in the journal Nature.
