Anyone concerned by the idea that people might try to combat global warming by injecting tons of sulfate aerosols into Earth’s atmosphere may want to read an article in the May 1 issue of the journal Geology.

New research on projected climate changes from the University of Helsinki indicates that climate change has an alarming potential to increase the damage caused to Norway spruce trees by a naturally circulating disease spreading fungus.

GOES-16, the most advanced weather satellite NOAA has ever developed, will be moved to the GOES-East position at 75 degrees west longitude, once it is declared operational in November. Top officials from NOAA announced the long-awaited decision at today’s 2017 Atlantic Hurricane Season Outlook news conference in College Park, Maryland.

Engineers at the University of California, Riverside have developed a new way to recover almost 100 percent of the water from highly concentrated salt solutions. The system will alleviate water shortages in arid regions and reduce concerns surrounding high salinity brine disposal, such as hydraulic fracturing waste.

Overheated cities face climate change costs at least twice as big as the rest of the world because of the ‘urban heat island’ effect, new research shows.

The study by an international team of economists of all the world’s major cities is the first to quantify the potentially devastating combined impact of global and local climate change on urban economies.

British Columbia’s forestry sector can potentially make a major contribution to meeting the province’s climate targets through using a mix of regionally-specific harvest and stand management techniques, bioenergy investments and creating more long-lived wood products.

That’s a key message from a public presentation held this morning by the Forest Carbon Management Project, a multi-year collaborative effort created by the Pacific Institute for Climate Solutions (PICS), involving scientists from Natural Resources Canada (NRCan), the University of British Columbia (UBC) and other agencies.

Climate change may keep you awake – and not just metaphorically. Nights that are warmer than normal can harm human sleep, researchers show in a new paper, with the poor and elderly most affected. According to their findings, if climate change is not addressed, temperatures in 2050 could cost people in the United States millions of additional nights of insufficient sleep per year. By 2099, the figure could rise by several hundred million more nights of lost sleep annually.

The study was led by Nick Obradovich, who conducted much of the research as a doctoral student in political science at the University of California San Diego. He was inspired to investigate the question by the heat wave that hit San Diego in October of 2015. Obradovich was having trouble sleeping. He tossed and he turned, the window AC in his North Park home providing little relief from the record-breaking temperatures. At school, he noticed that fellow students were also looking grumpy and bedraggled, and it got him thinking: Had anyone looked at what climate change might do to sleep?

Scientists using a high-resolution global climate model and historical observations of species distributions on the Northeast U.S. Shelf have found that commercially important species will continue to shift their distribution as ocean waters warm two to three times faster than the global average through the end of this century. Projected increases in surface to bottom waters of  6.6 to 9 degrees F (3.7 to 5.0 degrees Celsius) from current conditions are expected.

The findings, reported in Progress in Oceanography, suggest ocean temperature will continue to play a major role in where commercially important species will find suitable habitat. Sea surface temperatures in the Gulf of Maine have warmed faster than 99 percent of the global ocean over the past decade.  Northward shifts of many species are already happening, with major changes expected in the complex of species occurring in different regions on the shelf, and shifts from one management jurisdiction to another. These changes will directly affect fishing communities, as species now landed at those ports move out of range, and new species move in.

New research from a multi-university team of biologists shows what could be a startling drop in the amount of carbon stored in the Sierra Nevada mountains due to projected climate change and wildfire events.

The study, “Potential decline in carbon carrying capacity under projected climate-wildfire interactions in the Sierra Nevada”, published this week in Scientific Reports, shows another facet of the impact current man-made carbon emissions will have on our world if big changes aren’t made.

“What we’ve been trying to do is really understand how changing climate, increases in temperatures and decreases in precipitation, will alter carbon uptake in forests,” said University of New Mexico Assistant Professor Matthew Hurteau, a co-author on the paper. “The other aspect of this work is looking at disturbance events like large scale wildfires. Those events volatilize a lot of carbon and can kill many trees, leaving fewer trees to continue to take up the carbon.”

El Niño is a recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific. Two back-to-back 3-D visualizations track the changes in ocean temperatures and currents, respectively, throughout the life cycle of the 2015-2016 El Niño event, chronicling its inception in early 2015 to its dissipation by April 2016. Blue regions represent colder and red regions warmer temperatures when compared with normal conditions.

Under normal conditions, equatorial trade winds in the Pacific Ocean blow from east to west, causing warm water to pile up in the Western Pacific, while also causing an upwelling—the rise of deep, cool water to the surface—in the Eastern Pacific. During an El Niño, trade winds weaken or, as with this latest event, sometimes reverse course and blow from west to east. As a result, the warm surface water sloshes east along the equator from the Western Pacific and temporarily predominates in the Central and Eastern Pacific Ocean. At that same time, cooler water slowly migrates westward just off the equator in the Western Pacific.
