Deep snow cover in the Arctic region intensifies heat waves in Eurasia

Fri, 08/30/2019 - 18:28
Variations in the depth of snow cover in the Arctic region from late winter to spring determines the summer temperature pattern in Eurasia, according to new research. In particular, deeper-than-usual snow cover in Western Russia enhanced the likelihood of summer heat waves in Europe and Northeast Asia in recent years.

What if we paid countries to protect biodiversity?

Fri, 08/30/2019 - 18:28
Researchers have developed a financial mechanism to support the protection of the world's natural heritage. In a recent study, they developed three different design options for an intergovernmental biodiversity financing mechanism. Asking what would happen if money was given to countries for providing protected areas, they simulated where the money would flow, what type of incentives this would create - and how these incentives would align with international conservation goals.

Amazon deforestation has a significant impact on the local climate in Brazil

Fri, 08/30/2019 - 18:28
The loss of forest cover in the Amazon has a significant impact on the local climate in Brazil, according to a new study.

Defrosting surfaces in seconds

Fri, 08/30/2019 - 18:28
Researchers have developed a way to remove ice and frost from surfaces extremely efficiently, using less than 1% of the energy and less than 0.01% of the time needed for traditional defrosting methods. Instead of conventional defrosting, which melts all the ice or frost from the top layer down, the researchers established a technique that melts the ice where the surface and the ice meet, so the ice can simply slide off.

Uncovering ocean iron-level mystery

Fri, 08/30/2019 - 01:42
A new study uncovered the reason behind chemistry variations in the North Pacific Subtropical Gyre ecosystem.

Deep-sea sediments reveal solar system chaos: An advance in dating geologic archives

Thu, 08/29/2019 - 22:07
Scientists used geologic records from deep-sea drill cores to extend the astronomical time scale beyond 50 million years, by about 8 million years. Using their new chronology, they provide a new age for the Paleocene-Eocene boundary (56.01 Ma) with a small margin of error (0.1%).

Global warming may diminish plant genetic variety in Central Europe

Thu, 08/29/2019 - 22:07
Only a few individuals of a plant species may be prepared for increasing droughts.

Ancient civilizations were already messing up the planet

Thu, 08/29/2019 - 22:07
As issues like climate change, global warming, and renewable energy dominate the national conversation, it's easy to assume these topics are exclusive to the modern world. But a huge collaborative study in Science reveals that early humans across the entire globe were changing and impacting their environments as far back as 10,000 years ago.

Seaweed farming as a versatile tool in effort to mitigate climate change

Thu, 08/29/2019 - 19:42
Addressing carbon emissions from our food sector is absolutely essential to combating climate change. While land and agriculture took center stage in the panel's most recent report, missing was how the oceans at large could help in that fight.

What a Virginia wildflower can tell us about climate change

Thu, 08/29/2019 - 19:21
When climates change, plants and animals often are forced to colonize new areas -- or possibly go extinct. Because the climate is currently changing, biologists are keenly interested in predicting how climate-induced migrations influence organisms over time.

Bacteria feeding on Arctic algae blooms can seed clouds

Thu, 08/29/2019 - 18:54
New research finds Arctic Ocean currents and storms are moving bacteria from ocean algae blooms into the atmosphere where the particles help clouds form. These particles, which are biological in origin, can affect weather patterns throughout the world, according to the new study.

Burgundy wine grapes tell climate story, show warming accelerated in past 30 years

Thu, 08/29/2019 - 15:14
A new series of dates of grape harvest covering the past 664 years is the latest line of evidence confirming how unusual the climate of the past 30 years has been. The record shows wine grapes in Burgundy, France, have been picked 13 days earlier on average since 1988 than they were in the previous 6 centuries, pointing to the region's hotter and drier climate in recent years.

Extreme mangrove corals found on the Great Barrier Reef

Thu, 08/29/2019 - 15:13
The first documented discovery of 'extreme corals' in mangrove lagoons around Australia's Great Barrier Reef is yielding important information about how corals deal with environmental stress, scientists say. Thirty four species of coral were found to be regularly exposed to extreme low pH, low oxygen and highly variable temperature conditions making two mangrove lagoons on the Woody Isles and Howick Island potential 'hot-spots' of coral resilience.

Ancient die-off greater than the dinosaur extinction

Thu, 08/29/2019 - 01:04
When significant oxygen entered the atmosphere, ancient life multiplied. But after a few hundred million years, Earth's oxygen plummeted, resulting in a die-off likely greater than the extinction of the dinosaurs.

Climate change affects floods in Europe

Wed, 08/28/2019 - 21:01
For a long time, scientists argued whether or not climate change is affecting floods. No clear trends seemed to be evident. Now, in a major international study, data from numerous measurement stations all across Europe have been evaluated. The data clearly shows that climate change is indeed influencing the magnitude of flood events. However, climate change has different consequences in different regions.

Climate change, human activity lead to nearshore coral growth decline

Wed, 08/28/2019 - 21:01
New research compares the growth rates between nearshore and offshore corals in the Belize Mesoamerican Barrier Reef System, the world's second-largest reef system. While nearshore corals have historically grown faster than those offshore, over the past decade there was a decline in the growth rates of two types of nearshore corals, while offshore coral growth rates in the same reef system stayed the same.

More rain yet less water expected for up to 250 million people along the Nile

Wed, 08/28/2019 - 17:39
An increase in the frequency of hot and dry years could impact the water and food supplies for hundreds of millions of people in the Upper Nile region toward the end of the century.

Europe warming faster than expected due to climate change

Wed, 08/28/2019 - 17:05
Climate change is increasing the number of days of extreme heat and decreasing the number of days of extreme cold in Europe, posing a risk for residents in the coming decades, according to a new study.

Nuclear winter would threaten nearly everyone on Earth

Wed, 08/28/2019 - 15:05
If the United States and Russia waged an all-out nuclear war, much of the land in the Northern Hemisphere would be below freezing in the summertime, with the growing season slashed by nearly 90 percent in some areas, according to a new study. Indeed, death by famine would threaten nearly all of the Earth's 7.7 billion people, according to the research.

Scientists call for infiltration to be better incorporated into land surface models

Wed, 08/28/2019 - 15:05
Soil scientists can't possibly be everywhere at once to study every bit of soil across the planet. Plus, soils are constantly changing.
