Amount of carbon stored in forests reduced as climate warms

Altai Mountains, Russia. Credit: © tilpich / Adobe Stock Accelerated tree growth caused by a warming climate does not necessarily translate into enhanced carbon storage, an international study suggests. The team, led by the University of Cambridge, found that as temperatures increase, trees grow faster, but they also tend to die younger. When these fast-growing…

Nearly a quarter of West Antarctic ice is now unstable

A team of researchers, led by Professor Andy Shepherd from…

Iceland volcano eruption in 1783-84 did not spawn extreme heat wave

Volcanic landscape in Lakagigar. Credit: © estivillml / Adobe Stock An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study. The study, in the Journal of Geophysical Research: Atmospheres, will…

Warming climate threatens microbes in alpine streams

But streams that are…

From Earth’s deep mantle, scientists find a new way volcanoes form

Volcanic eruption (stock image).

Scientists…

How climate change will affect the rural northeast: Expect three weeks...

Heat wave concept, with thermometer. Credit: © nnudoo / Adobe Stock While extreme cold and snow often make headlines in the Northeast, by 2060, there will be far more record heat. Imagine the most sweltering day of the year. By 2060, you will experience that type of hot day for approximately three weeks of the…

Mapping microbial symbioses in forests

Tree with moss on roots. Credit: © andreiuc88 / Adobe Stock In and around the tangled roots of the forest floor, fungi and bacteria grow with trees, exchanging nutrients for carbon in a vast, global marketplace. A new effort to map the most abundant of these symbiotic relationships -- involving more than 1.1 million forest…

Electrode’s ‘hot edges’ convert carbon dioxide gas into fuels and chemicals

Models of carbon dioxide molecules. Credit: © hooyah808 / Adobe Stock A team of scientists has created a bowl-shaped electrode with 'hot edges' which can efficiently convert CO2 from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide. The research team, from the University of Bath,…

How potatoes could thrive in a warmer world

Potatoes in the field. Credit: © natara / Adobe Stock If there's one thing potato plants don't like, it's heat. If the temperature is too high, potato plants form significantly lower numbers of tubers or sometimes none at all. Biochemists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered the reason why. If the temperature rises, a…

New data platform illuminates history of humans’ environmental impact

Animal bones on display. Credit: © DedMityay / Adobe Stock The human environmental footprint is not only deep, but old. Ancient traces of this footprint can be found in animal bones, shells, scales and antlers at archaeological sites. Together, these specimens tell the millennia-long story of how humans have hunted, domesticated and transported animals, altered…

‘Impossible’ research produces 400-year El Niño record, revealing startling changes

Coral reef. Credit: © borisoff / Adobe Stock Australian scientists have developed an innovative method using cores drilled from coral to produce a world first 400-year long seasonal record of El Niño events, a record that many in the field had described as impossible to extract. The record published today in Nature Geoscience detects different…

Their work, appearing May 1 in the journal iScience, finds that compared to other…

Climate change is giving old trees a growth spurt

Tree rings.

Just one-third of the world’s longest rivers remain free-flowing

Yukon River. Credit: © bildmacher / Adobe Stock Just over one-third (37%) of the world's 246 longest rivers remain free-flowing, according to a new study published in the scientific journal Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe. A team of 34…

Localized efforts to save coral reefs won’t be enough, study suggests
