UK waters hit with extreme heatwave as global sea temperatures reach record levels
Experts warn that some marine species are at risk of ‘mass mortality events’ in ever-warming oceansUK waters are being hit with an “extreme” marine heatwave, the Met Office has said, as scientists warn that high ocean temperatures globally could result in “mass-mortality events”
Slowing Atlantic current could fuel stronger California atmospheric rivers by century's en
A slowing Atlantic Ocean current is projected to intensify powerful storms in California while reducing snowfall over Greenland, according to a recent University of California, Riverside study. The Atlantic Meridional Overturning Circulation (AMOC) works like a giant conveyor bel

Low-e windows keep homes cool … but may set neighbours’ property on fire
Low-emissivity windows also keep houses warm in winter, but use on bowed glass can have magnifying-glass effectLow-emissivity or low-E window glass is a useful green technology for keeping buildings warm in winter and cool in summer … but a rare side-effect can set the neighbours
Trees keep absorbing carbon long after they stop growing
Trees keep absorbing carbon long after they stop growing
Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a war
Stress protection of Amazon trees, induced by climate warming, may alter atmosphere chemis
The Amazon rainforest is one of the largest carbon reservoirs on Earth. It is also the world's largest source of biogenic volatile organic compounds (VOCs). These carbon-based gases are naturally released by vegetation. They protect trees against various sources of stress, e.g.,
Ancient rocks reveal Earth's past warm periods were cooler than thought
Ancient rocks reveal Earth's past warm periods were cooler than thought
Earth's temperature has been much cooler in the past than previously thought, meaning it could be moving toward the warmest it's ever been.
Morning glories reveal 96% drop in adaptation as pollinator pressure reshapes evolution
Facing both climate change and a crashing pollinator population, plants may be evolving to attract pollinators rather than adapting to a warming climate, and the trade-off has resulted in a steep decline in plants' rate of adaptation, according to a University of Michigan study.

Warm Jupiter exoplanet transiting a sun-like star discovered
An international team of astronomers reports the discovery of a new exoplanet orbiting a sunlike star as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-39 b, is a Jupiter-sized planet with an equilibrium temperature of about 519 K. Th
Moderate warming rewires one-third of microalga's genes, study finds
Moderate warming rewires one-third of microalga's genes, study finds
Researchers have demonstrated for the first time that the microalga Chlamydomonas reinhardtii alters the activity of about one-third of its protein-coding genes in response even to moderate temperature changes. The study, published in the journal The Plant Cell, points to far-rea
Scientists finally solved the mystery of Earth's greatest mass extinction
Scientists finally solved the mystery of Earth's greatest mass extinction
Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms
Climate oscillations shape nature's coral refuges in a warming ocean
Climate oscillations shape nature's coral refuges in a warming ocean
Why do some coral reefs weather marine heat waves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ocean basins. By combining long-term ocean observation

Weather tracker: Unusually warm rivers affect French nuclear power plants
High temperatures and below average rainfall put pressure on waterways used to cool reactorsAbove average temperatures combined with below average rainfall across much of western and central Europe during June and the first half of July have placed increasing pressure on rivers,
