Protected Areas Help Waterbirds Adapt to Climate Change

Climate change pushes species distribution areas northward. However, the expansion of species ranges is not self-evident due to e.g. habitat degradation and unsustainable harvesting caused by human ...

Severe Air Pollution Drives Food Delivery Consumption and Plastic Waste

When the air outside is bad, office workers are more likely to order food delivery than go out for lunch, which in turn increases plastic waste from food packaging, according to a study by ...

A Renewable Solution to Keep Cool in a Warming World

Month-after-month, year-after-year, the world continues to experience record high temperatures. In response to this and exacerbated by a growing global population, it is expected that ...

Microbial Diversity Below Seafloor Is as Rich as on Earth's Surface

For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. The research team discovered that microbial diversity in the dark, ...

Deep Sea Coral Time Machines Reveal Ancient CO2 Burps

The fossilized remains of ancient deep-sea corals may act as time machines providing new insights into the effect the ocean has on rising CO2 ...

Arctic Ocean Sediments Reveal Permafrost Thawing During Past Climate Warming

Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of ...

Are Climate Scientists Being Too Cautious When Linking Extreme Weather to Climate Change?

Climate science has focused on avoiding false alarms when linking extreme events to climate change. But it could learn from how weather forecasters warn the public of hazardous events to include a ...

Long-Term Data Show a Recent Acceleration in Chemical and Physical Changes in the Ocean

New research uses data from two sustained open-ocean hydrographic stations in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The ...

Unprecedented Energy Use Since 1950 Has Transformed Humanity's Geologic Footprint

A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as ...

Fraction of Money Earmarked for COVID-19 Recovery Could Boost Climate Efforts

Global stimulus plans for economic recovery after the pandemic could easily cover climate-friendly policies, suggests a new ...

Understanding How Toxic PFAS Chemicals Spread from Release Sites

New lab studies are helping researchers to better understand how so called 'forever chemicals' behave in soil and water, which can help in understanding how these contaminants ...

Climate Change Likely Drove Early Human Species to Extinction, Modeling Study Suggests

Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study combining climate modeling and the fossil record in ...

Artificial Cyanobacterial Biofilm Can Sustain Green Ethylene Production for Over a Month

Ethylene is one of the most important and widely used organic chemicals. A research group has designed a thin-layer artificial biofilm with embedded cyanobacterial cell factories which were ...

Fuels, Not Fire Weather, Control Carbon Emissions in Boreal Forest

A team has found that the amount of carbon that burns in wildfires in western boreal forests depends more on available fuels than on fire weather such as drought conditions, temperature, or ...

COVID-19 Lockdowns Averted Tens of Thousands of Premature Deaths Related to Air Pollution, Study Finds

Scientists have found that particulate matter concentrations in China dropped by an unprecedented 29.7 percent, and by 17.1 percent in parts of Europe, during lockdowns that took place between Feb. 1 ...

More Diversity Needed in Oil Palm Plantations

Growing global demand for palm oil has led to a rapid spread of oil palm monoculture plantations in South East Asia, often associated with the loss of habitats and biodiversity. Plantations are ...

Thawing Permafrost Releases Organic Compounds Into the Air

When permafrost thaws due to global warming, not only the greenhouse gases known to all, but also organic compounds are released from the soil. They may have a significant impact on climate ...

Recent Atlantic Ocean Warming Unprecedented in Nearly 3,000 Years

Sediments from a lake in the Canadian High Arctic allow climate scientists to extend the record of Atlantic sea-surface temperature from about 100 to 2,900 years. It shows that the warmest interval ...

Plastic Bags Could Be 'Eco-Friendlier' Than Paper and Cotton

Scientists have modeled the cradle-to-grave environmental impact of using different types of shopping bags and report that in cities like Singapore, single-use plastic bags (made from high-density ...
