Published Measuring the extent of global droughts in unprecedented detail



While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists have come up with a new set of data that shows how the total distribution of water over the Earth's land surfaces has changed over the past 20 years more accurately than ever before.
Published Then vs. now: Did the Horn of Africa reach a drought tipping point 11,700 years ago?



If climate models predict that much of tropical Africa will become wetter with a warming climate, then why does it keep getting drier in the Horn of Africa?
Published Telecommunications cable used to track sea ice extent in the Arctic



A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report.
Published An early warning system for joint heat and ozone extremes in China



Scientists have identified large-scale climate patterns that could be used to predict the co-occurrence of extreme heat and ozone days in China months before they occur. Like predictions for hurricane and wildfire seasons, the forecasts could help the government prepare resources and implement policies to mitigate the severity of the season.
Published New Antarctic extremes 'virtually certain' as world warms



Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
Published Current estimates of Lake Erie algae toxicity may miss the mark



A new study analyzing toxins produced by Microcystis, the main type of cyanobacteria that compose the annual harmful algal bloom (HAB) in Lake Erie, suggests that the toxicity of the bloom may be overestimated in earlier warm months and underestimated later in the summer.
Published Study examines Earth and Mars to determine how climate change affects the paths of rivers



The study investigated why the paths of meandering rivers change over time and is a step toward understanding what the hydroclimate on Mars was like when there was still surface water.
Published The history and future of ancient einkorn wheat Is written in its genes



Researchers have sequenced the complete genome for einkorn wheat, the world's first domesticated crop and traced its evolutionary history. The information will help researchers identify genetic traits like tolerance to diseases, drought and heat, and re-introduce those traits to modern bread wheat.
Published Sea level rise shifts habitat for endangered Florida Keys species



A newly published study describes the response to sea level rise by the silver rice rat, an endangered species only found in the Florida Keys.
Published North Atlantic Oscillation contributes to 'cold blob' in Atlantic Ocean



A patch of ocean in the North Atlantic is stubbornly cooling while much of the planet warms. This anomaly -- dubbed the 'cold blob' -- has been linked to changes in ocean circulation, but a new study found changes in large-scale atmospheric patterns may play an equally important role, according to an international research team.
Published California's winter waves may be increasing under climate change



A new study uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.
Published Secondary forests more sensitive to drought than primary forests



The dry summer of 2018 hit Swedish forests hard -- and hardest affected were the managed secondary forests.
Published New research method determines health impacts of heat and air quality



The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Risk of fatal heart attack may double in heat wave and high fine particulate pollution days



An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
Published Long-term changes in waves and storm surges have not impacted global coastlines



Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found.
Published Climate science is catching up to climate change with predictions that could improve proactive response



In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and resilience programming in the most food insecure countries of the world.
Published Our favorite vintages and their precarious mountainside homes are at risk due to climate change, environmental scientists warn



Tucked into the hillsides of Italy, Portugal, and Spain, some of the world's most famous -- and most difficult to maintain -- vineyards are heralded for their unique flavor profiles and centuries of tradition. But as extreme weather and changing socioeconomic conditions make this so-called 'heroic viticulture' even more challenging, scientists worry these grapes and their cultural histories are at risk. Researchers argue that farmers and scientists must work together to protect some of the world's most celebrated wines.
Published Supercomputer used to simulate winds that cause clear air turbulence


Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.
Published Marine heat waves caused mass seabird die-offs, beach surveys show



New research uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper shows that persistent marine heat waves lead to massive seabird die-offs months later.
Published Three things to know: Climate change's impact on extreme-weather events



Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
