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.

Positives of climate change? Agricultural, economic possibilities for West Virginia

Tue, 08/27/2019 - 19:35
Researchers found that, between 1900 and 2016, maximum temperatures in West Virginia trended downward, average minimum temperatures ascended and annual precipitation increased. Even so, he predicts future climates in West Virginia will be more conducive to agricultural production.

Glacier-fed rivers may consume atmospheric carbon dioxide

Tue, 08/27/2019 - 19:35
Glacier-fed rivers in northern Canada may be consuming significant amounts of carbon dioxide from the atmosphere, according to new research.

Would a carbon tax help to innovate more-efficient energy use?

Tue, 08/27/2019 - 18:11
Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new article.

Satellite-based estimates of reduced deforestation in protected areas needed

Tue, 08/27/2019 - 18:11
In the context of progressing towards new targets for a post-2020 Global Biodiversity Framework, the debate remains on whether the emphasis should be on protected area coverage or protected area effectiveness.

Affordable, less intensive methane detection protocol

Tue, 08/27/2019 - 18:11
A new testing protocol that uses existing, affordable water chemistry tests can help scientists and regulators detect sites showing evidence of new methane gas leaks caused by oil and gas drilling, according to researchers.

Bad Blooms: Researchers review environmental conditions leading to harmful algae blooms

Tue, 08/27/2019 - 16:50
When there is a combination of population increase, wastewater discharge, agricultural fertilization, and climate change, the cocktail is detrimental to humans and animals. This harmful cocktail produces harmful algal blooms, and many of these are toxic to humans and wildlife.

Chipping away at how ice forms could keep windshields, power lines ice-free

Tue, 08/27/2019 - 15:47
How does ice form? Surprisingly, science hasn't fully answered that question. But researchers today will explain their finding that the arrangements that surface atoms impose on water molecules are the key. Their work has implications for preventing ice formation on windshields, ships and power lines, and for improving weather prediction.

Deep transformations needed to achieve Sustainable Development Goals

Mon, 08/26/2019 - 18:27
The Sustainable Development Goals and the Paris Agreement on Climate Change call for deep transformations that require complementary actions by governments, civil society, science, and business.

Wildfires could permanently alter Alaska's forest composition

Mon, 08/26/2019 - 18:26
A team of researchers projected that the combination of climate change and increased wildfires will cause the iconic evergreen conifer trees of Alaska to get pushed out in favor of broadleaf deciduous trees, which shed their leaves seasonally.

Big increase in ocean carbon dioxide absorption along West Antarctic Peninsula

Mon, 08/26/2019 - 18:26
Climate change is altering the ability of the Southern Ocean off the West Antarctic Peninsula to absorb carbon dioxide, according to a new study, and that could magnify climate change in the long run.

Salt marshes' capacity to sink carbon may be threatened by nitrogen pollution

Mon, 08/26/2019 - 16:23
Salt marshes sequester carbon at rates an order of magnitude higher than land ecosystems. A new study indicates nitrate pollution of coastal waters stimulates the decomposition of organic matter in salt marsh sediments that normally would have remained stable, and can alter the capacity of salt marshes to sequester carbon over the long term.

'100-year' floods will happen every 1 to 30 years, according to new flood maps

Thu, 08/22/2019 - 23:50
Researchers have developed new maps that predict coastal flooding for every county on the Eastern and Gulf Coasts and find 100-year floods could become annual occurrences in New England; and happen every one to 30 years along the southeast Atlantic and Gulf of Mexico shorelines.
