This Year is on Track to be Earth’s Warmest on Record, Beating 2016, NOAA says

/in , , /by /The Washington Postby Andrew Freedman

There is a 75 percent chance 2020 will set a record for the warmest year since instrument records began in 1880, the National Oceanic and Atmospheric Administration is projecting, beating out 2016 for the distinction.

This is somewhat unexpected, since there is no declared El Niño event in the tropical Pacific Ocean, which tends to provide a natural boost to global temperatures that are already elevated due to the human-caused buildup of greenhouse gases in the atmosphere.

The NOAA projection, made late last week, is based on statistical modeling now that the first quarter of 2020 is off to a near-record warm start, coming in as the second-warmest January through March period since instrument records began in 1880.

Changes in Snowmelt Threaten Farmers in Western U.S.

/in , , /by /Colorado State Universityby Mary Guiden

For decades, scientists have thought that changes in snowmelt due to climate change could negatively impact agriculture. Now, a new study reveals the risks to agriculture around the world from changes in snowmelt, finding that farmers in parts of the western United States who rely on snowmelt to help irrigate crops will be among the hardest hit in the world by climate change.

In a study published April 20 in Nature Climate Change, an interdisciplinary team of researchers analyzed monthly irrigation water demand with snowmelt runoff across global basins from 1985 to 2015. The goal was to determine where irrigated agriculture has depended on snowmelt runoff in the past and how that might change with a warming climate.

An effort to bolster food bank supplies and fight hunger in San Diego County is getting a helping hand from the region’s public water agencies.

The San Diego County Water Authority and its member agencies are supporting a virtual food drive in partnership with the Jacobs & Cushman San Diego Food Bank. The campaign allows donors to select and purchase items such as canned meats, vegetables, fruits, peanut butter and oatmeal for distribution to needy residents. To donate, go to www.bit.ly/SDWaterAgencyFoodDrive.

Opinion: California’s Drought Without End

/in , , /by /San Francisco Chronicleby Chronicle Editorial Board

Californians tend to regard our droughts in seasonal and annual terms: The winter storms fill reservoirs with rain and mountains with snow, or they don’t, or sometimes, like this year, they do so in the spring. But a new study proposes a broader perspective in which recent years’ shifts from dry to wet to weird are just minor variations within a longer and more extraordinary period of widespread parching.

Study: Snowpack Will Become a Less Reliable Predictor of Drought in Western U.S.

/in , , /by /Colorado Public Radioby Grace Hood

In the next 16-45 years, two-thirds of Western states may have to turn away from snowpack and find new tools to predict drought.

And by the late century, scientists estimate that area will grow to four-fifths of the western United States, according to a new paper in Nature Climate Change.

“When the temperature warms, the phase of the precipitation is likely to change from snow to rain. So less snowpack is something that’s pretty likely,” said lead author Ben Livneh, an assistant professor of civil, environmental and architectural engineering at the University of Colorado Boulder.
