Impacts of climate change on our water and energy systems: it's complicated

Mon, 01/11/2021 - 16:42
Researchers have developed a science-based analytic framework to evaluate the complex connections between water and energy, and options for adaptations in response to an evolving climate.

Understanding origins of Arizona's Sunset Crater eruption of 1,000 years ago

Mon, 01/11/2021 - 15:42
Scientists have been working to solve the mysterious root cause of the Sunset Crater eruption and any lessons learned to better understand the threats similar volcanoes may pose around the world today. But as to why it erupted, that has remained a mystery, until now. Recent research shows the importance of carbon dioxide in volcanic eruptions.

Positive 'tipping points' offer hope for climate

Mon, 01/11/2021 - 02:24
Positive 'tipping points' could spark cascading changes that accelerate action on climate change, experts say.

Scientists develop a cheaper method that might help create fuels from plants

Fri, 01/08/2021 - 18:10
Scientists have figured out a cheaper, more efficient way to conduct a chemical reaction at the heart of many biological processes, which may lead to better ways to create biofuels from plants.

New analysis highlights importance of groundwater discharge into oceans

Fri, 01/08/2021 - 15:41
An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes of water and dissolved material entering the sea from rivers and streams, but a new study finds groundwater discharge plays a more significant role than had been thought.

Research confirms increase in river flooding and droughts in US, Canada

Thu, 01/07/2021 - 20:57
Research demonstrates that increases in the frequency of both high- and low-flow extreme streamflow events 'are, in fact, widespread.'

Power, water and climate

Thu, 01/07/2021 - 19:52
As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California's energy goes toward water-related activities, while more than a tenth of the state's electricity comes from hydropower. As society tries to adapt to one challenge, it needs to ensure it doesn't worsen the other.

Hawai'i drought during El Niño winter? Not always, according to new research

Thu, 01/07/2021 - 18:24
El Niño events have long been perceived as a driver for low rainfall in the winter and spring in Hawai'i, creating a six-month wet-season drought. However, a recent study revealed the connection between Hawai'i winter rainfall and El Niño is not as straightforward as previously thought.

Rising lizard temperatures may change predator-prey relationship with snakes

Thu, 01/07/2021 - 18:24
Researchers have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes. The findings show that lizard thermal biology is highly dependent on predation pressures and that body temperatures are rising suggest that such ectothermic predator-prey relationships may be changing under climatic warming.

Native biodiversity collapse in the Eastern Mediterranean

Thu, 01/07/2021 - 18:24
An international team quantified a dramatic biodiversity collapse of up to 95 per cent of native species in the Eastern Mediterranean.

Modern microbes provide window into ancient ocean

Wed, 01/06/2021 - 21:26
Roughly two billion years ago, microorganisms called cyanobacteria fundamentally transformed the globe. Researchers are now stepping back to that pivotal moment in Earth's history.

Will global warming bring a change in the winds? Dust from the deep sea provides a clue

Wed, 01/06/2021 - 18:20
Climate researchers describe a new method of tracking the ancient history of the westerly winds--a proxy for what we may experience in a future warming world.

The new face of the Antarctic

Wed, 01/06/2021 - 16:53
In the future, the Antarctic could become a greener place and be colonized by new species. At the same time, some species will likely disappear.

Dungeness crab fishing industry response to climate shock

Tue, 01/05/2021 - 23:08
Fishermen contend with regulations, natural disasters, and the ups and downs of the stocks they fish, along with many other changes. As a result, fishing communities are quite resilient. That is, they can withstand, recover from, and adapt to change.

Identifying Canada's key conservation hot spots highlights problem

Tue, 01/05/2021 - 20:57
To stop biodiversity loss, Canada recently committed to protecting 30% of its land and sea by 2030. But making conservation decisions about where to locate new protected areas is complicated. It depends on data both about biodiversity and about a range of benefits (e.g. freshwater, climate regulation, recreation) that people get from nature. Despite the size of the country, new mapping suggests that less than 1% of Canada's land is a hot spot, providing all these benefits in one place.

Climate change caused mangrove collapse in Oman

Tue, 01/05/2021 - 20:01
Most of the mangrove forests on the coasts of Oman disappeared about 6,000 years ago. Until now, the reason for this was not entirely clear. A current study now sheds light on this: It indicates that the collapse of coastal ecosystems was caused by climatic changes.

Leaf fossils show severe end-Cretaceous plant extinction in southern Argentina

Tue, 01/05/2021 - 20:01
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants that they relied on for food. Fossil leaf assemblages from Patagonia, Argentina, suggest that vegetation in South America suffered great losses but rebounded quickly, according to an international team of researchers.

Drought of the century in the Middle Ages -- with parallels to climate change today?

Tue, 01/05/2021 - 20:01
The transition from the Medieval Warm Period to the Little Ice Age was apparently accompanied by severe droughts between 1302 and 1307 in Europe. Researchers write that the 1302-07 weather patterns display similarities to the 2018 weather anomaly, in which continental Europe experienced exceptional heat and drought.

Imminent sudden stratospheric warming to occur, bringing increased risk of snow over coming weeks

Tue, 01/05/2021 - 18:18
A new study helps to shed light on the winter weather we may soon have in store following a dramatic meteorological event currently unfolding high above the North Pole.

Rare footage captured of jaguar killing ocelot at waterhole

Tue, 01/05/2021 - 16:56
In what may be a sign of climate-change-induced conflict, researchers have captured rare photographic evidence of a jaguar killing another predatory wild cat at an isolated waterhole in Guatemala.
