For this ocean dweller, ability to respond to warming waters is about location

Fri, 09/27/2019 - 18:25
A new study seeks to tease out some of the myriad pressures that drive adaptation in small, widely dispersed marine animals called copepods.

Longest coral reef survey to date reveals major changes in Australia's Great Barrier Reef

Fri, 09/27/2019 - 14:49
An in-depth look at Australia's Great Barrier Reef over the past 91 years concludes that since 1928 intertidal communities have experienced major phase-shifts as a result of local and global environmental change, leaving few signs that reefs will return to their initial state in the near future. The long-term implications of these changes highlight the importance of avoiding phase shifts in coral reefs which may take many decades to repair, if at all.

Hurricanes: Improving rapid intensification predictions

Thu, 09/26/2019 - 18:40
Many scientists have said that storms are more intense than ever before - Cat. 4 or 5 storms used to be outliers, but today, it seems they are becoming the norm. Why? That's the question a research team is working to answer - they are looking what contributes to the rapid intensification of storms.

Farmed oysters able to protect themselves from acidification

Thu, 09/26/2019 - 18:26
Oysters bred for fast growth and disease resistance are able to adapt their shell growth to protect themselves from environmental acidification, according to new research.

Thousands of meltwater lakes mapped on the east Antarctic ice sheet

Thu, 09/26/2019 - 17:58
The number of meltwater lakes on the surface of the East Antarctic Ice Sheet is more significant than previously thought, according to new research.

Climate change could cause drought in wheat-growing areas

Wed, 09/25/2019 - 22:40
Wheat supplies about 20 percent of all calories consumed by humans. In a new study, researchers found that up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century.

Humankind did not live with a high-carbon dioxide atmosphere until 1965

Wed, 09/25/2019 - 19:34
Humans have never before lived with the high carbon dioxide atmospheric conditions that have become the norm on Earth in the last 60 years, according to a new study.

Aerosols from coniferous forests no longer cool the climate as much

Wed, 09/25/2019 - 18:51
Emissions of greenhouse gases have a warming effect on the climate, whereas small airborne particles in the atmosphere, aerosols, act as a cooling mechanism. That is the received wisdom in any case. However, new research can now show that the tiniest aerosols are increasing at the expense of the normal sized and slightly larger aerosols -- and it is only the latter that have a cooling effect.

New satellite may make flood prediction easier

Wed, 09/25/2019 - 18:51
A satellite on schedule to launch in 2021 could offer a more comprehensive look at flooding in vulnerable, under-studied parts of the world, including much of Africa, South America and Indonesia, a new study has found.

High carbon dioxide can create 'shrinking stems' in marshes

Wed, 09/25/2019 - 18:29
For most plants, carbon dioxide acts like a steroid: The more they can take in, the bigger they get. But scientists have now discovered something strange happening in marshes. Under higher levels of carbon dioxide, instead of producing bigger stems, marsh plants produced more stems that were noticeably smaller.

Potentially large economic impacts of climate change can be avoided by human actions

Wed, 09/25/2019 - 17:04
A study estimates global-scale, multi-sectoral economic impacts of climate change, and suggests that a plausible range of decisions and actions by humans can determine the scale of the economic impacts, even if the uncertainty in the climate response to increased greenhouse gas concentration is considered. These actions include reductions of greenhouse gas emissions and improvement of socioeconomic conditions. This study highlights the importance of societal changes and the current generation's responsibility for the future.

Hurricane resilience in the bahamas: Ecosystem

Tue, 09/24/2019 - 22:43
A new study provides information on how to invest in natural coastal ecosystems that the Bahamian government, community leaders and development banks are applying in post-disaster recovery and future storm preparation in the Bahamas.

Model helps choose wind farm locations, predicts output

Tue, 09/24/2019 - 22:13
The wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger. Now a team of researchers has a model that can locate the best place for the wind farm and even help with 24-hour predictions of energy output.

Tale of two climate crises gives clues to the present

Tue, 09/24/2019 - 19:50
Figuring out what lies ahead for our species and our planet is one of the most pressing and challenging tasks for climate scientists. While models are very useful, there is nothing quite like Earth's history to reveal details about how oceans, animals, and plants respond to and recover from a warming world.

How and when was carbon distributed on Earth?

Tue, 09/24/2019 - 17:40
A magma ocean existing during the core formation is thought to have been highly depleted in carbon due to its high-siderophile (iron loving) behavior. Thus, most of the carbon forming the atmosphere and life on Earth may have been delivered by a carbon-rich embryo after the core formation. However, a new high-pressure experiment has shown that previous studies may have overestimated the amount of carbon partitioning to the core.

Scientists decode DNA of coral and all its microscopic supporters

Tue, 09/24/2019 - 17:14
Scientists have seen for the first time how corals collaborate with other microscopic life to build and grow.

New report deepens understanding of wind-wildlife interactions

Mon, 09/23/2019 - 21:08
An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.

Is theory on Earth's climate in the last 15 million years wrong?

Mon, 09/23/2019 - 18:12
A key theory that attributes the climate evolution of the Earth to the breakdown of Himalayan rocks may not explain the cooling over the past 15 million years, according to a new study. The study could shed more light on the causes of long-term climate change. It centers on the long-term cooling that occurred before the recent global warming tied to greenhouse gas emissions from humanity.

New evidence of the Sahara's age

Mon, 09/23/2019 - 17:19
The Sahara Desert is vast, generously dusty, and surprisingly shy about its age. New research looking into what appears to be dust that the Sahara blew over to the Canary Islands is providing the first direct evidence from dry land that the age of the Sahara matches that found in deep-sea sediments: at least 4.6 million years old.

Why are mountains so high? It doesn't add up

Mon, 09/23/2019 - 16:31
Researchers have analyzed mountain ranges worldwide to show that a theory relating erosion and mountain height doesn't always add up.
