Gulf coast mollusks rode out past periods of climate change

Science Daily: Climate News - Mon, 02/10/2020 - 22:33
About 55 million years ago, a rapidly warming climate decimated marine communities around the world. But according to new research, it was a different story for snails, clams and other mollusks living in the shallow waters along what is now the Gulf Coast of the United States. They were able to survive.

Twist in the story of volcanism and mass extinctions

Science Daily: Climate News - Mon, 02/10/2020 - 21:48
An emerging scientific consensus is that gases -- in particular carbon gases -- released by volcanic eruptions millions of years ago contributed to some of Earth's greatest mass extinctions. But new research suggests that that's not the entire story.

Global warming and extinction risk

Science Daily: Climate News - Mon, 02/10/2020 - 20:32
How can fossils predict the consequences of climate change? A research team compared data from fossil and marine organisms living today to predict which groups of animals are most at risk from climate change.

New research supports previous studies on global sea level rise

Science Daily: Climate News - Mon, 02/10/2020 - 16:53
Using data from European satellites, a student has demonstrated that the global sea level rise has accelerated over the past four decades.

'Rule breaking' plants may be climate change survivors

Science Daily: Climate News - Mon, 02/10/2020 - 16:11
Plants that break some of the 'rules' of ecology by adapting in unconventional ways may have a higher chance of surviving climate change, according to researchers.

Acid-loving microbe can improve understanding of past climate

Science Daily: Climate News - Mon, 02/10/2020 - 14:42
Study of an 'extremophile' found in the hot springs of Yellowstone National Park can be used to help researchers understand climate change.

El Niño contributes to insect collapse in the Amazon

Science Daily: Climate News - Mon, 02/10/2020 - 14:42
Hotter and drier El Niño events are having an alarming effect on biodiversity in the Amazon Rainforest and further add to a disturbing global insect collapse, scientists show. A new study focusing on the humble, but ecologically key, dung beetle has revealed for the first time that intense droughts and wildfires during the last El Niño climate phenomenon, combined with human disturbance, led to beetle numbers falling by more than half -- with effects lasting for at least two years.

Scientists warn humanity about worldwide insect decline

Science Daily: Climate News - Mon, 02/10/2020 - 14:42
Insect declines and extinctions are accelerating in many parts of the world. With this comes the disappearance of irreplaceable services to humans, the consequences of which are unpredictable. A group of scientists from across the globe has united to warn humanity of such dangers.

Arctic ice melt is changing ocean currents

Science Daily: Climate News - Fri, 02/07/2020 - 16:57
Using 12 years of satellite data, NASA scientists have measured how the influx of cold, fresh water is affecting the Beaufort Gyre, a major Arctic current.

Majority of US adults believe climate change is most important issue today

Science Daily: Climate News - Fri, 02/07/2020 - 16:54
As the effects of climate change become more evident, more than half of US adults (56%) say climate change is the most important issue facing society today, yet 4 in 10 have not made any changes in their behavior to reduce their contribution to climate change, according to a new poll.

At least 13% of wastewater treated by Southern Ontario septic systems ends up in streams

Science Daily: Climate News - Thu, 02/06/2020 - 15:04
The presence of artificial sweeteners has revealed that at least 13 percent of septic system wastewater from rural Southern Ontario homes eventually makes its way into local streams.

New global biodiversity study provides unified map of life on land and in the ocean

Science Daily: Climate News - Wed, 02/05/2020 - 21:33
A new study offers the most complete picture available of where life occurs on Earth and what the most critical environmental factors are for determining why it's in specific places. The study's authors envision it providing a way to adapt management practices as climate change disrupts ecosystems across the planet.

Extreme weather conditions can tax urban drainage systems to the max

Science Daily: Climate News - Wed, 02/05/2020 - 20:23
During a typical Canadian winter, snow accumulation and melt -- combined with sudden rainfalls -- can lead to bottlenecks in storm drains that can cause flooding. With that in mind, researchers have been examining urban stormwater drainage systems, and they too have concerns about the resilience of many urban drainage systems.

Ocean temperatures impact Central American climate more than once thought

Science Daily: Climate News - Wed, 02/05/2020 - 20:22
Researchers examined the rainfall history of Central America over the last 11,000 years. The results provide context for the development of tropical rainforest ecosystems in the region, and long-sought answers to what has been controlling rainfall in Central America for several millennia.

Global cooling after nuclear war would harm ocean life

Science Daily: Climate News - Wed, 02/05/2020 - 15:42
A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.
