Collapse of the Atlantic Ocean heat transport might lead to hot European summers

Severe winters combined with heat waves and droughts during summer in Europe. Those were the consequences as the Atlantic Ocean heat transport nearly collapsed 12,000 years ago. The same situation might occur today. »

Tiny microenvironments in the ocean hold clues to global nitrogen cycle

A new study shows that nitrogen-feeding organisms exist all over the deep ocean, and not just in large oxygen-depleted 'dead zones,' changing the way we think about the delicate nitrogen cycle. »

Climate change mitigation project threatens local ecosystem resilience in Ethiopia

To increase forest cover in the Global South in order to mitigate climate change does not always have positive effects, as shown in a new study in southern Ethiopia. It can also threaten biodiversity and the survival of unique alpine plants. »

Algae-forestry, bioenergy mix could help make CO2 vanish from thin air

An unconventional mélange of algae, eucalyptus and bioenergy with carbon capture and storage appears to be a quirky ecological recipe. But, scientists have an idea that could use that recipe to help power and provide food protein to large regions of the world -- and simultaneously remove carbon dioxide from Earth's atmosphere. »

Nature-based solutions can prevent $50 billion in Gulf Coast flood damages

While coastal development and climate change are increasing the risk of flooding for communities along the US Gulf Coast, restoration of marshes and oyster reefs are among the most cost-effective solutions for reducing those risks, according to a new study. »

1C rise in atmospheric temperature causes rapid changes to world's largest High Arctic lake

An interdisciplinary team of scientists examining everything from glaciology to freshwater ecology discovered drastic changes over the past decade to the world's largest High Arctic lake. And from glacial melt to the declining lake ice to changes in lake ecology, the results from Lake Hazen on Ellesmere Island in Canada are alarming. »

Global warming can turn monarch butterflies' favorite food into poison

Researchers have discovered a new relationship between climate change, monarch butterflies and milkweed plants. It turns out that warming temperatures don't just affect the monarch, Danaus plexippus, directly, but also affect this butterfly by potentially turning its favorite plant food into a poison. »

Iconic swallowtail butterfly at risk from climate change

New research reveals that Norfolk's butterflies, bees, bugs, birds, trees and mammals are at major risk from climate change as temperatures rise. Researchers carried out the first in-depth audit of its kind for a region in the UK to see how biodiversity might be impacted in Norfolk as the world warms. »

Rapid emissions reductions would keep CO2 removal and costs in check

Rapid greenhouse-gas emissions reductions are needed if governments want to keep in check both the costs of the transition towards climate stabilization and the amount of removing already emitted CO2 from the atmosphere. To this end, emissions in 2030 would need to be at least 20 percent below what countries have pledged under the Paris climate agreement, a new study finds. »
