Potential Effects of Large-Scale Projects Designed to Offset Earth's Changing Climate

Apr. 16, 2019 — Climate engineering research is too focused on specific aspects of individual projects, argues an expert. She believes broader studies about the impacts of these efforts will have on other Earth ... read more

Apr. 16, 2019 — On March 17, 2002, the satellite duo GRACE was launched to map the Earth's gravity field more precisely than ever before. The measurements make it possible to monitor the terrestrial water ... read more

Predictability Limit: Scientists Find Bounds of Weather Forecasting

Apr. 15, 2019 — In the future, weather forecasts that provide storm warnings and help us plan our daily lives could come up to five days sooner before reaching the limits of numerical weather prediction, scientists ... read more

Apr. 15, 2019 — Researchers say mercury buried in ancient rock provides the strongest evidence yet that volcanoes caused the biggest mass extinction in the history of the Earth. The extinction 252 million years ago ... read more

Apr. 15, 2019 — Researchers have examined the sediments in the Dead Sea. The geologists drilled a 400-meter hole before analyzing each layer of sediment and the traces of a strategy that enables bacteria to survive ... read more

Electric Vehicle Adoption Improves Air Quality and Climate Outlook

Apr. 12, 2019 — A new study quantified the differences in air pollution generated from battery-powered electric vehicles versus internal combustion engines. The researchers found that even when their electricity is ... read more

Apr. 12, 2019 — Primitive ponds may have provided a suitable environment for brewing up Earth's first life forms, more so than oceans, a new study finds. Researchers report that shallow bodies of water, on the ... read more

Apr. 12, 2019 — The origin of giant apatite-iron oxide ores of the so-called 'Kiruna-type' has been the topic of a long standing debate that has lasted for over 100 years. In a new article, scientists ... read more

Apr. 12, 2019 — A study revealed that the bacteria present in the water overlying dozens of coral reefs changed dramatically during the night, and then returned to the same daytime community as observed the morning ... read more

Apr. 12, 2019 — Research that reveals what lies at the bottom of the deepest part of the ocean -- the Mariana Trench. Until now, scientists knew more about Mars than the deepest part of the ocean. But an expedition ... read more

Apr. 11, 2019 — Researchers have developed a new algorithm to bolster what once were static models of root dynamics, providing researchers a clearer picture of what's really happening beneath the soil. The work ... read more

Rethinking Conservation Efforts for Improved Biodiversity

Apr. 11, 2019 — A new study looked into why the global commitment towards the expansion of protected areas has not delivered the expected conservation benefits. Researchers propose a new target and a set of ... read more

Apr. 11, 2019 — Earth's steady state is warm and balmy, but half a dozen times over the past billion years, the planet developed ice caps and glaciers. Researchers have now amassed evidence that these cold ... read more

Apr. 11, 2019 — New research shows that the Larsen C ice shelf -- the fourth largest ice shelf in Antarctica -- experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017. ... read more

Apr. 11, 2019 — Evidence of historic marine life present in Alaskan permafrost is helping scientists reconstruct ancient changes in the ice cover over the Arctic ... read more

Where Will Flooded Fields Best Replenish Groundwater?

Apr. 10, 2019 — Overpumping in California's Central Valley has depleted groundwater storage capacity and caused the land to sink. A new model based on remote sensing data could help zero in on where water ... read more

Falling Levels of Air Pollution Drove Decline in California's Tule Fog

Apr. 10, 2019 — The Central Valley's heavy wintertime tule fog -- known for snarling traffic and closing schools -- has been on the decline over the past 30 years, and falling levels of air pollution are the ... read more

How Severe Drought Influences Ozone Pollution

Apr. 10, 2019 — From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation. Drought conditions can have complicated effects on ozone ... read more

Apr. 9, 2019 — A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation ... read more

The Oldest Ice on Earth May Be Able to Solve the Puzzle of the Planet's Climate History

Apr. 9, 2019 — Scientists want to drill a 1.5 million year old ice core in Antarctica. An analysis of the climate data stored in the ice should contribute to a better understanding of the alternation between warm ... read more
