Heat and cold waves affect people with certain health conditions differently, highlighting the need for tailored public service risk communication.

Large wildfires cause increases in stream flow that can last for years or even decades, according to a new analysis of 30 years of data from across the continental United States.

As expected, Tropical Cyclone Keni followed a track similar to Tropical Cyclone Josie and passed to the southwest of Fiji's main island of Viti Levu on April 10, 2018 (UTC).

European tourists are more frequently going to places all over the world with significant tsunami risk, researchers have found. A global tourism destination risk index for tsunamis was released today at the 2018 Annual Conference of the European Geosciences Union (EGU) in Vienna, based on a study led by Andreas Schaefer of Karlsruhe Institute of Technology (KIT).  This study examined all prominent tourism destinations globally with regard to the potential tourism loss impact for businesses given the loss of beaches post-tsunami. 

Coastal waters play an important role in the carbon cycle by transferring carbon to the open ocean or burying it in wetland soils and ocean sediments, a new study shows.

A range of less than one degree Fahrenheit (or half a degree Celsius) of climate warming over the next century could make all the difference when it comes to the probability of future ice-free summers in the Arctic, new CU Boulder research shows.

In 1878, the American geologist and explorer John Wesley Powell drew an invisible line in the dirt—a very long line. It was the 100th meridian west, the longitude he identified as the boundary between the humid eastern United States and the arid Western plains. Running south to north, the meridian cuts northward through the eastern states of Mexico, and on to Texas, Oklahoma, Kansas, Nebraska, the Dakotas, and the Canadian province of Manitoba on its way to the pole. Powell, best known for exploring the Grand Canyon and other parts of the West, was wary of large-scale settlement in that often harsh region, and tried convincing Congress to lay out water and land-management districts crossing state lines to deal with environmental constraints. Western political leaders hated the idea—they feared this might limit development, and their own power—and it never went anywhere. It was not the first time that politicians would ignore the advice of scientists.

NASA satellite imagery showed that Tropical Cyclone Keni was being battered by vertical wind shear. NASA-NOAA's Suomi NPP satellite revealed that wind shear was pushing the clouds and storms associated with Keni to the southeast of the center.

The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations.

Glaciers in the high mountain regions of the Himalayas offer a different picture to our Alpine glaciers: many of them are completely covered in debris, and many areas are overlooked by steep ice walls – vertical cliffs up to 30 metres high. From a distance, this makes the glacier surface look like the warty skin of a toad.
