July 2019 was hottest month on record for the planet

Thu, 08/15/2019 - 20:08
Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows.

Warmer winters are changing the makeup of water in Black Sea

Thu, 08/15/2019 - 19:06
Warmer winters are starting to alter the structure of the Black Sea, which could foreshadow how ocean compositions might shift from future climate change, according to new research.

Data assimilation method offers improved hurricane forecasting

Thu, 08/15/2019 - 18:37
Operational models for severe weather forecasting predicted Hurricane Harvey would become a Category 1 hurricane in 2017. Instead, it became a massive Category 4 just before it made landfall, tying Hurricane Katrina for the costliest hurricane on record.

Climate change 'disrupts' local plant diversity, study reveals

Thu, 08/15/2019 - 18:37
Researchers have discovered that the numbers of plant species recorded by botanists have increased in locations where the climate has changed most rapidly, and especially in relatively cold parts of the world.

Ice sheets impact core elements of the Earth's carbon cycle

Thu, 08/15/2019 - 15:12
The Earth's carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate.

Microplastic drifting down with the snow

Wed, 08/14/2019 - 21:45
Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow -- and even in such remote regions as the Arctic and Alps.

Cool roofs can help shield California's cities against heat waves

Wed, 08/14/2019 - 16:38
A new study shows that if every building in California sported 'cool' roofs by 2050, these roofs would help contribute to protecting urbanites from the consequences of dangerous heatwaves.

Fracking prompts global spike in atmospheric methane, study suggests

Wed, 08/14/2019 - 16:06
As methane concentrations increase in the Earth's atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new research.

Air pollution can accelerate lung disease as much as a pack a day of cigarettes

Wed, 08/14/2019 - 01:08
Air pollution -- especially ozone air pollution which is increasing with climate change -- accelerates the progression of emphysema of the lung, according to a new study.

Non-native invasive insects, diseases decreasing carbon stored in US forests

Wed, 08/14/2019 - 00:07
Scientists have found that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.

Arctic could be iceless in September if temps increase 2 degrees

Tue, 08/13/2019 - 23:05
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study.

Microbes have adapted to live on food that is hundreds of years old

Tue, 08/13/2019 - 23:05
Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a new study.

Key factors in how some algae harness solar energy

Tue, 08/13/2019 - 20:42
Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

How media around the world frame climate change news

Tue, 08/13/2019 - 20:04
Researchers analyzed thousands of climate change articles from 45 countries and territories around the world to determine how they frame the issue, and differences were revealed mostly by the wealth of the nation.

Satellite study reveals that area in Africa emits one billion tonnes of carbon

Tue, 08/13/2019 - 18:22
A vast region of Africa affected by drought and changing land use emits as much carbon dioxide each year as 200 million cars, research suggests.

Human impacts on oceans nearly doubled in recent decade

Tue, 08/13/2019 - 17:19
Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action.

Icebergs delay Southern Hemisphere future warming, study shows

Tue, 08/13/2019 - 00:23
Future warming can accelerate the disintegration of the West Antarctic ice sheet. A large fraction of the ice will enter the Southern Ocean in form of icebergs, which melt and provide a cooling and freshening effect to the warmer and denser ocean water. This process will increase the formation of sea-ice and shift winds and ocean currents. The overall effect is a slowdown in the magnitude of human-induced Southern Hemispheric warming and sea-level rise, according to a new study.

Study examines a million corals one by one in urgent call to save reefs

Mon, 08/12/2019 - 21:49
Scientists have completed a landmark study on how to save coral reefs in the Indian and Pacific Oceans.

Natural-gas leaks are important source of greenhouse gas emissions in Los Angeles

Mon, 08/12/2019 - 21:49
Scientist have found that methane in L.A.'s air correlates with the seasonal use of gas for heating homes and businesses.

Structurally complex forests better at carbon sequestration

Mon, 08/12/2019 - 20:08
Forests in the eastern United States that are structurally complex -- meaning the arrangement of vegetation is highly varied -- sequester more carbon, according to a new study. The study demonstrates for the first time that a forest's structural complexity is a better predictor of carbon sequestration potential than tree species diversity. The discovery may hold implications for the mitigation of climate change.
