Health risks to babies on the front line of climate change

Science Daily: Climate News - 3 hours 52 min ago
Extreme rainfall associated with climate change is causing harm to babies in some of the most forgotten places on the planet setting in motion a chain of disadvantage down the generations, according to new research. Researchers found babies born to mothers exposed to extreme rainfall shocks, were smaller due to restricted fetal growth and premature birth.

Global warming poses threat to food chains

Science Daily: Climate News - 3 hours 52 min ago
Rising temperatures could reduce the efficiency of food chains and threaten the survival of larger animals, new research shows.

Half a trillion corals: Coral count prompts rethink of extinction risks

Science Daily: Climate News - 3 hours 53 min ago
Scientists have assessed how many corals there are in the Pacific Ocean -- half a trillion -- and evaluated their risk of extinction at the same time.

Hotter, drier, CRISPR: editing for climate change

Science Daily: Climate News - 3 hours 53 min ago
Just 15 plant crops provide 90 per cent of the world's food calories. A review of genome editing technologies states gene editing technology could play a vital role to play in climate-proofing future crops to protect global food security. The review recommends integrating CRISPR-Cas9 genome editing into modern breeding programs for crop improvement in cereals.

Identified: A mechanism that protects plant fertility from stress

Science Daily: Climate News - 3 hours 53 min ago
As temperatures rise due to global warming the need to protect plants from stressful conditions has increased, as stress can cause a loss in yield and cause further impact economically. Researchers have successfully identified two proteins that protect crops from stress, which is key in safeguarding food production.

Rocket launches reveal water vapor effect in upper atmosphere

Science Daily: Climate News - 6 hours 5 min ago
Results of a 2018 multirocket launch will help scientists better understand the impact of more water vapor accumulating near the fringe of the Earth's atmosphere.

Climate change threatens European forests

Science Daily: Climate News - 6 hours 5 min ago
Well over half of Europe's forests are potentially at risk from windthrow, forest fire and insect attacks.

When using pyrite to understand Earth's ocean and atmosphere: Think local, not global

Science Daily: Climate News - Sat, 02/27/2021 - 15:33
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.

Under climate stress, human innovation set stage for population surge

Science Daily: Climate News - Fri, 02/26/2021 - 19:12
Aridification in the central plains of China during the early Bronze Age did not cause population collapse, a result that highlights the importance of social resilience to climate change. Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population around 3,900 to 3,500 years ago.

Stark warning: Combating ecosystem collapse from the tropics to the Antarctic

Science Daily: Climate News - Fri, 02/26/2021 - 17:37
Eminent scientists warn that key ecosystems around Australia and Antarctica are collapsing, and propose a three-step framework to combat irreversible global damage.

Post-wildfire landslides becoming more frequent in southern California

Science Daily: Climate News - Thu, 02/25/2021 - 21:38
Southern California can now expect to see post-wildfire landslides occurring almost every year, with major events expected roughly every ten years, a new study finds. The results show Californians are now facing a double whammy of increased wildfire and landslide risk caused by climate change-induced shifts in the state's wet and dry seasons, according to researchers who mapped landslide vulnerability in the southern half of the state.

Gulf Stream System at its weakest in over a millennium

Science Daily: Climate News - Thu, 02/25/2021 - 18:33
Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. Researchers compiled proxy data, reaching back hundreds of years to reconstruct the AMOC flow history. They found consistent evidence that its slowdown in the 20th century is unprecedented in the past millennium.

Forests' long-term capacity to store carbon is dropping in regions with extreme annual fires

Science Daily: Climate News - Thu, 02/25/2021 - 18:33
Researchers have analysed decades' worth of data on the impact of repeated fires on ecosystems across the world. Their results show that repeated fires are driving long-term changes to tree communities and reducing their population sizes.

Extreme melt on Antarctica's George VI ice shelf

Science Daily: Climate News - Thu, 02/25/2021 - 18:33
Antarctica's northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared to 31 previous summers of dramatically lower melt, a new study found. Using satellite observations that detect meltwater on top of the ice and within near-surface snow, the researchers found the most widespread melt of any season. Surface meltwater ponding is potentially dangerous to ice shelves because when these lakes drain, the ice fractures and may trigger ice-shelf break-up.

Climate change-driven snowmelt in Alps triggers abrupt seasonal change

Science Daily: Climate News - Thu, 02/25/2021 - 18:33
Spring snowmelt in the Alps is occurring earlier in the year due to climate change and as a result triggering abrupt deviations in mountain ecosystems. These changes could negatively affect the functioning of these valuable ecosystems.

Short-term climate modeling forecasts drought for Southeast US

Science Daily: Climate News - Thu, 02/25/2021 - 18:32
Many climate models focus on scenarios decades into the future, making their outcomes seem unreliable and problematic for decision-making in the immediate future. In a proactive move, researchers are using short-term forecasts to stress the urgency of drought risk in the United States and inform policymakers' actions now.

How wildfires may have larger effects on cloud formation than previously thought

Science Daily: Climate News - Thu, 02/25/2021 - 18:32
As the frequency and size of wildfires continues to increase worldwide, new research shows how the chemical aging of the particles emitted by these fires can lead to more extensive cloud formation and intense storm development in the atmosphere.

The risks of communicating extreme climate forecasts

Science Daily: Climate News - Thu, 02/25/2021 - 15:25
Apocalypse now? The all-too-common practice of making climate doomsday forecasts is not just bad science, it's also a terrible way to communicate important information.

Previously, this dataset was (temporarily?) not available. Perhaps ERDDAP was just restarted.

Record-high Arctic freshwater will flow to Labrador Sea, affecting local and global oceans

Science Daily: Climate News - Wed, 02/24/2021 - 21:35
The Arctic Ocean's Beaufort Sea has increased its freshwater content by 40% over the past two decades. When conditions change this freshwater will travel to the Labrador Sea off Canada, rather than through the wider marine passageways that connect to seas in Northern Europe. This has implications for local marine environments and global ocean circulation.
