Closing critical gap in weather forecasting

Sat, 12/07/2019 - 14:35
Scientists working on the next frontier of weather forecasting are hoping that weather conditions 3-to-4 weeks out will soon be as readily available as seven-day forecasts. Having this type of weather information--called subseasonal forecasts--in the hands of the public and emergency managers can provide the critical lead time necessary to prepare for natural hazards like heat waves or the next polar vortex.

As China rapidly adopts clean energy, use of traditional stoves persists

Thu, 12/05/2019 - 22:53
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.

Can Arctic 'ice management' combat climate change?

Thu, 12/05/2019 - 20:06
According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter.

Damaging rains from hurricanes more intense after winds begin to subside

Thu, 12/05/2019 - 20:05
Howling wind drives torrential rain sideways as tall, slender palms bow and tree limbs snap. A hurricane approaches, its gale-force winds wreaking havoc as it nears the coast. Storm surges combine with the downpour, inundating the area with water.

First 'lab in a field' experiment reveals a sunnier side of climate change

Thu, 12/05/2019 - 18:31
Pioneering experiments using heated field plots to test the responses of crops to temperature have revealed an unexpected plus side of climate change for farmers.

Carbon emissions from volcanic rocks can create global warming

Thu, 12/05/2019 - 14:30
Greenhouse gas emissions released directly from the movement of volcanic rocks are capable of creating massive global warming effects -- a discovery which could transform the way scientists predict climate change, a new study reveals.

Less rice, more nutritious crops will enhance India's food supply

Thu, 12/05/2019 - 00:04
India can sustainably enhance its food supply if its farmers plant less rice and more nutritious and environmentally-friendly crops, including finger millet, pearl millet, and sorghum, according to a new study.

Gulf of Mexico coral reefs to protect from storm surge in the future -- But will they?

Thu, 12/05/2019 - 00:03
Researchers used 120,000-year-old fossils to predict how Gulf of Mexico coral reefs will respond to climate change toward the end of this century.

Atmospheric river storms create $1 billion-a-year flood damage

Wed, 12/04/2019 - 22:28
Researchers found that flooding has caused nearly $51 billion in damages to western states in the last 40 years. More than 84 percent of these damages were caused by atmospheric rivers (ARs), long narrow corridors of water vapor in the atmosphere capable of carrying more than twice the volume of the Amazon river through the sky.

Warmer temperatures will increase arsenic levels in rice

Wed, 12/04/2019 - 22:28
Researchers have found that warmer temperatures, at levels expected under most climate change projections, can lead to higher concentrations of arsenic in rice grains.

Outlook for the polar regions in a 2-degrees-warmer world

Wed, 12/04/2019 - 21:49
With 2019 on pace as one of the warmest years on record, a major new study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming. The study reports that the Arctic has warmed by 0.75 degrees C in the last decade alone.

Looking at tropical forests through new eyes

Wed, 12/04/2019 - 21:49
Air-based maps of plant chemistry are improving carbon cycling models in hyper-diverse tropical forests.

Lake methane emissions should prompt rethink on climate change

Wed, 12/04/2019 - 19:45
Study sheds new light on the impact of natural methane production on global climate change assessments.

As a way to fight climate change, not all soils are created equal

Wed, 12/04/2019 - 17:05
Soil scientists offer a newly nuanced understanding of different soil organic matter components that can be increased through varied management strategies.

Scientists devise catalyst that uses light to turn carbon dioxide to fuel

Wed, 12/04/2019 - 17:05
Scientists have used sunlight and a catalyst largely made of copper to transform carbon dioxide to methanol.

Global carbon emissions growth slows, but hits record high

Wed, 12/04/2019 - 16:08
Coal use is down dramatically in the United States and the European Union, and renewable energy is gaining traction. But rising natural gas and oil use in 2019 increased the world's carbon dioxide emissions modestly for a third straight year.

Migratory birds shrinking as climate warms, new analysis of four-decade record shows

Wed, 12/04/2019 - 16:08
North American migratory birds have been getting smaller over the past four decades, and their wings have gotten a bit longer. Both changes appear to be responses to a warming climate.

For some corals, meals can come with a side of microplastics

Tue, 12/03/2019 - 21:52
A new experiment has found that some corals are more likely to eat microplastics when they are consuming other food, yet microplastics alone are undesirable.

Great Barrier Reef study shows how reef copes with rapid sea-level rise

Tue, 12/03/2019 - 18:45
A survey of coral reef cores on the Great Barrier Reef has revealed how it has responded to recent periods of rapid sea-level rise. The study, covering the past 9000 years, has revealed a system in delicate balance.

Finnish rivers transport carbon to Baltic Sea at an increasing rate

Tue, 12/03/2019 - 17:20
The amount of carbon transported via Finnish rivers to the Baltic Sea has risen substantially in the past few decades. The researchers don't know the exact effects yet.
