Arctic sea-ice loss has 'minimal influence' on severe cold winter weather

Mon, 08/12/2019 - 20:08
The dramatic loss of Arctic sea ice through climate change has only a 'minimal influence' on severe cold winter weather across Asia and North America, new research has shown.

Diet change needed to save vast areas of tropics

Mon, 08/12/2019 - 17:28
One quarter of the world's tropical land could disappear by the end of the century unless meat and dairy consumption falls, researchers have warned.

Climate change conversations can be difficult for both skeptics, environmentalists

Sat, 08/10/2019 - 22:19
Having productive conversations about climate change isn't only challenging when dealing with skeptics, it can also be difficult for environmentalists, according to two new studies.

Despite temperature shifts, treehoppers manage to mate

Fri, 08/09/2019 - 22:47
A rare bright spot among dismal climate change predictions, new research findings show that some singing insects are likely to manage to reproduce even in the midst of potentially disruptive temperature changes.

Ten years of icy data show the flow of heat from the Arctic seafloor

Fri, 08/09/2019 - 01:57
In addition to 10 years of data on the flow of heat in the Arctic ocean seafloor, researchers have published an analysis of that data using modern seismic data.

Back-to-back low snow years will become more common

Thu, 08/08/2019 - 22:25
Consecutive low snow years may become six times more common across the Western United States over the latter half of this century, leading to ecological and economic challenges such as expanded fire seasons and poor snow conditions at ski resorts, according to a new study.

Persistent impacts of smoke plumes aloft

Thu, 08/08/2019 - 22:25
Thunderstorms generated by a group of giant wildfires in 2017 injected a small volcano's worth of aerosol into the stratosphere, creating a smoke plume that lasted for almost nine months. Scientists now explore implications for climate modeling, including models of nuclear winter and geoengineering.

Why humans in Africa fled to the mountains during the last ice age

Thu, 08/08/2019 - 22:25
People in Ethiopia did not live in low valleys during the last ice age. Instead they lived high up in the inhospitable Bale Mountains where they had enough water, built tools out of obsidian and relied mainly on giant mole rats for nourishment.Researchers provides the first evidence that our African ancestors had already settled in the mountains during the Palaeolithic period, about 45,000 years ago.

Over a century of Arctic sea ice volume reconstructed with help from historic ships' logs

Thu, 08/08/2019 - 20:35
A new study provides a 110-year record of the total volume of Arctic sea ice, using early US ships' voyages to verify the earlier part of the record. The current sea ice volume and rate of loss are unprecedented in the 110-year record.

Installing solar panels on agricultural lands maximizes their efficiency

Thu, 08/08/2019 - 19:38
A new study finds that if less than 1% of agricultural land was converted to solar panels, it would be sufficient to fulfill global electric energy demand.

Using lasers to visualize molecular mysteries in our atmosphere

Thu, 08/08/2019 - 18:14
Molecular interactions between gases and liquids underpin much of our lives, but difficulties in measuring gas-liquid collisions have so far prevented the fundamental exploration of these processes. Researchers hope their new technique of enabling the visualization of gas molecules bouncing off a liquid surface will help climate scientists improve their predictive atmospheric models.

Marine heatwaves a bigger threat to coral reefs than previously thought, scientists find

Thu, 08/08/2019 - 18:14
Marine heatwaves are a much bigger threat to coral reefs than previously thought, research revealing a previously unrecognized impact of climate change on coral reefs has shown.

When invasive plants take root, native animals pay the price

Thu, 08/08/2019 - 18:14
Biologists have completed a comprehensive meta-analytic review examining the ecological impacts of invasive plants by exploring how animals -- indigenous and exotic -- respond to these nonnative plants.

Stony corals: Limits of adaption

Thu, 08/08/2019 - 17:38
Corals have been dominant framework builders of reef structures for millions of years. Ocean acidification, which is intensifying as climate change progresses, is increasingly affecting coral growth. Scientists have now answered some questions regarding whether and how corals can adapt to these changes by having gained important insights into the regulatory processes of coral calcification.

Oil rigs could pump CO2 emissions into rocks beneath North Sea

Thu, 08/08/2019 - 17:03
North Sea oil and gas rigs could be modified to pump vast quantities of carbon dioxide emissions into rocks below the seabed, research shows.

Earth's last magnetic field reversal took far longer than once thought

Thu, 08/08/2019 - 16:14
Every several hundred thousand years or so, Earth's magnetic field dramatically shifts and reverses its polarity. Geologist found that the most recent field reversal, some 770,000 years ago, took at least 22,000 years to complete. That's several times longer than previously thought, and the results further call into question controversial findings that some reversals could occur within a human lifetime.

A marine microbe could play increasingly important role in regulating climate

Wed, 08/07/2019 - 21:22
Marine microbes with a special metabolism are ubiquitous and could play an important role in how Earth regulates climate.

Groundwater resources in Africa resilient to climate change

Wed, 08/07/2019 - 20:19
Groundwater - a vital source of water for drinking and irrigation across sub-Saharan Africa - is resilient to climate variability and change, according to a new study.

A rocky relationship: A history of Earth's continents breaking up and getting back together

Wed, 08/07/2019 - 20:19
A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics, or the movement of large pieces of Earth's outer shell, evolved over the planet's 4.56-billion-year history.

Climate change likely to increase human exposure to toxic methylmercury

Wed, 08/07/2019 - 20:19
Researchers developed a first-of-its-kind, comprehensive model that simulates how environmental factors, including increasing sea temperatures and overfishing, impact levels of methylmercury in fish. The researchers found that while the regulation of mercury emissions have successfully reduced methylmercury levels in fish, spiking temperatures are driving those levels back up and will play a major role in the methylmercury levels of marine life in the future.
