Drought researchers explore future challenges in managing water

California’s water troubles a harbinger of things to come worldwide, say scientists in new essay

California’s ongoing extreme drought must be a lesson for managing water in a warmer, more densely populated world, says a team of NOAA and University of California climatologists and hydrologists in an essay this week in Nature.

Earth is breathing deeper: Multi-agency study reveals widening seasonal swings in CO2 in the Northern Hemisphere

Levels of carbon dioxide in the atmosphere rise and fall annually as plants take up the gas in spring and summer and release it in fall and winter through photosynthesis and respiration. Now the range of that cycle is growing as more CO2 is emitted from the burning of fossil fuels and other human activities, according to a study published in Science by Scripps Institution of Oceanography, UC San Diego, with CIRES and NOAA co-authors.

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.

Los Angeles air pollution declining, losing its sting

The cleanup of California’s tailpipe emissions over the last few decades has not only reduced ozone pollution in the Los Angeles area, it has also altered the pollution chemistry in the atmosphere, making the eye-stinging “organic nitrate” component of air pollution plummet, according to a new study.
