How the Earth is Changing

Climate change is a complicated phenomenon with a variety of both abrupt and gradual effects that scientists are working hard to uncover. Emerging findings on how various ecosystems are responding to a changing climate, stemming from long-term research conducted through the National Science Foundation’s 40-year-old Long-Term Ecological Research (LTER) program, have now been published in […]

Mountain events could improve safety with ultra-high resolution weather models

In late May of 2021, 172 runners set out to tackle a 100-kilometer (62-mile) ultramarathon in northwestern China. By midday, as the runners made their way through a rugged, high-elevation part of the course, temperatures plunged, strong winds whipped around the hillslopes and freezing rain and hail pummeled the runners. By the next day, the […]

Risk of death rises as climate change causes nighttime temperatures to climb

Excessively hot nights caused by climate change are predicted to increase the mortality rate around the world by up to 60% by the end of the century, according to a new international study that features research from the UNC Gillings School of Global Public Health. Ambient heat during the night may interrupt the normal physiology […]

Tonga Eruption Blasted Unprecedented Amount of Water Into Stratosphere

The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in […]

Considering catastrophe: high-impact, low-probability climate scenarios “dangerously underexplored”

Researchers call for a new “Climate Endgame” agenda and say far too little work has gone into understanding the mechanisms by which rising temperatures might pose a “catastrophic” risk to society and humanity: For instance, if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed […]

Scientists reveal distribution of dark matter around galaxies 12 billion years ago–further back in time than ever before

A collaboration led by scientists at Nagoya University in Japan has investigated the nature of dark matter surrounding galaxies seen as they were 12 billion years ago, billions of years further back in time than ever before. Their findings, published in Physical Review Letters, offer the tantalizing possibility that the fundamental rules of cosmology may differ […]

Bacteria that causes rare disease Melioidosis discovered in U.S. environmental samples

The Centers for Disease Control and Prevention (CDC) has identified for the first time in domestic environmental samples the bacteria that causes a rare and serious disease called melioidosis. The bacteria, Burkholderia pseudomallei or B. pseudomallei, was identified through sampling of soil and water in the Gulf Coast region of Mississippi. It is unclear how […]

Overconfidence bolsters anti-scientific views, PSU study finds

Historically, the scientific community has relied on educating the public in order to increase agreement with scientific consensus. New research from Portland State University suggests why this approach has seen only mixed results.  “Human opposition to scientific consensus is an extremely important topic. For many years, smart people thought that the way to bring people […]

Water Resources to Become Less Predictable with Climate Change

Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere by later this century, according to a comprehensive new climate change study led by the National Center for Atmospheric Research (NCAR). The research team found that, even in regions that keep receiving about the same […]

Copernicus scientists warn of very high ozone pollution as heatwave continues across Europe

Scientists from the Copernicus Atmosphere Monitoring Service are predicting very high levels of surface ozone pollution across a large region of Europe as temperatures soar. Meanwhile, wildfires have been increasing across southern Europe. Scientists at The Copernicus Atmosphere Monitoring Service (CAMS) are warning very high levels of ozone pollution in southern Europe caused by the […]

Lasers light the way to discovery of an almost 4 billion-year-old piece of the Earth’s crust that lies beneath Australia

By firing lasers finer than a human hair at tiny grains of a mineral extracted from beach sand, Curtin researchers have found evidence of an almost four billion-year-old piece of the Earth’s crust that lies beneath the South-West of WA. In a new finding that helps explain the planet’s evolution from uninhabitable to life supporting, […]

U.S. supercomputers for weather and climate forecasts get major bump

Today, NOAA inaugurated the nation’s newest weather and climate supercomputers with an operational run of the National Blend of Models. The new supercomputers, first announced in Febuary 2020 with a contract award to General Dynamics Information Technology (GDIT), provide a significant upgrade to computing capacity, storage space and interconnect speed of the nation’s Weather and Climate Operational […]
