Methane leaks from three large U.S. natural gas fields in line with...

Tens of thousands of pounds of methane leak per hour from equipment in three major natural gas basins that span Texas, Louisiana, Arkansas and Pennsylvania, according to airborne measurements published today by a NOAA-led team of scientists. But the overall leak rate from those basins is only about one percent of gas production there—lower than leak rates measured in other gas fields, and in line with federal estimates.

Rivers in the sky

Yes, there are rivers in the sky!  Atmospheric rivers, to be exact, are narrow bands of moisture that regularly form above the Pacific Ocean and flow towards North America’s west coast, drenching it in rain and packing it with snow.   These rivers, which transport more water than the Amazon or the Mississippi, have a far-reaching impact - even on the food you may be eating today.

With this week’s  January 14 sailing of NOAA’s largest ship, the Ronald H. Brown, a major investigation of atmospheric rivers named CalWater 2015 is now underway.

Natural cycles, sea surface temperatures found to be main drivers in ongoing event

According to a new NOAA-sponsored study, natural oceanic and atmospheric patterns are the primary drivers behind California's ongoing drought. A high pressure ridge off the West Coast (typical of historic droughts) prevailed for three winters, blocking important wet season storms, with ocean surface temperature patterns making such a ridge much more likely. Typically, the winter season in California provides the state with a majority of its annual snow and rainfall that replenish water supplies for communities and ecosystems.

Climate change not to blame for 2013 Colorado floods

Heavy multi-day summer rain events not expected to increase in the area

Last September’s widespread flooding in northeast Colorado, which saw just over 17 inches of rain in one week in the city of Boulder, was not made more likely or more intense by the effects of human-induced climate change, according to a new NOAA-led study published today in the Bulletin of the American Meteorological Society.
