Watch this space! Next week, in partnership with experts from NOAA Chemical Sciences Lab and the Climate Prediction Center, we're launching a blog about the behavior—and sometimes misbehavior—of the stratospheric polar vortex.

It's not perfect, but ENSO is still the best tool we have for predicting average winter precipitation over the U.S.

Summary: Addressing climate issues takes a trusted leader who knows how to get things done in their community—a climate champion.  An effective champion, whether inside government or a member of the community at large, works with a planning team to assess climate risk and make recommendations on how to address it.

Earth’s hottest periods occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen.

This study reveals the potentially dominant role of anthropogenic forcing on coastal cyclone changes around the US Atlantic coast, Hawaii region, Northeast Asian coast near Japan and Korea, South China Sea, western coast of the Arabian Sea, and Madagascar.

For engineers and scientists, sometimes failure means progress. When developing a new technology, the process is to field test, fail, tweak, and test again, each time failing a little less and learning what does and does not work until–finally–they get it right.

A new study analyzes forecasts of acidity and oxygen at the ocean’s surface and subsurface. Combining data sources improves forecast skill up to ten months in advance.

A new study examines how well weather radar products can characterize wildfire and smoke behavior. The study finds that radar-based estimates can compensate for gaps in satellite data.

Scientists have long wanted to know more about what happens under the ice of the Great Lakes each winter. New tools built with NOAA’s industry partners may help fill the knowledge gap.

Summary: The Atlas is an extension of the Fifth National Climate Assessment (NCA5), providing interactive access to maps and data used in NCA5. The initial release offers maps showing 15 variables of downscaled climate projections at 4 levels of global warming.
