Geoengineering versus a volcano

Science Daily: Climate News - Mon, 08/05/2019 - 20:40
Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change?

Twelve centuries of European summer droughts

Science Daily: Climate News - Mon, 08/05/2019 - 18:22
Researchers have published a study exploring the association between summer temperature and drought across Europe placing recent drought in the context of the past 12 centuries. The study reveals that, throughout history, northern Europe has tended to get wetter and southern Europe to get drier during warmer periods.

Economic growth benefits wildlife but growing human populations do not

Science Daily: Climate News - Fri, 08/02/2019 - 16:24
Analysis shows that while national-level economic growth and social development -- including more women in government -- are associated with more abundant wildlife, growing human populations are linked to wildlife decline.

To learn how poison frogs are adapting to warmer temperatures, scientists got crafty

Science Daily: Climate News - Fri, 08/02/2019 - 16:24
Strawberry poison frogs live in Costa Rican forests that are being cut down for farmland. The deforested pastures are hotter and sunnier, so scientists wanted to see if the frogs had adapted to withstand the heat. They learned that the frogs from pastures had adapted to seek out warmer temperatures than frogs from forests. The maximum temperature they can stand didn't change, though -- so if global temperatures rise too much, the frogs are in trouble.

EU agriculture not viable for the future

Science Daily: Climate News - Thu, 08/01/2019 - 21:25
The current reform proposals of the EU Commission on the Common Agricultural Policy (CAP) are unlikely to improve environmental protection, say researchers. While the EU has committed to greater sustainability, this is not reflected in the CAP reform proposal.

From greenhouse gas to fuel

Science Daily: Climate News - Thu, 08/01/2019 - 19:26
Scientists have revealed a new approach to convert carbon dioxide gas into valuable chemicals and fuels.

US infrastructure unprepared for increasing frequency of extreme storms

Science Daily: Climate News - Thu, 08/01/2019 - 19:02
Current design standards for United States hydrologic infrastructure are unprepared for the increasing frequency and severity of extreme rainstorms, meaning structures like retention ponds and dams will face more frequent and severe flooding, according to a new study.

Ancient plankton help researchers predict near-future climate

Science Daily: Climate News - Thu, 08/01/2019 - 19:01
Temperature data inferred from plankton fossils from the Pliocene, an era with CO2 levels similar to today's, allowed a team to rectify discrepancies between climate models and other proxy temperature measurements.

Mastering metabolism for shark and ray survival

Science Daily: Climate News - Thu, 08/01/2019 - 16:33
Understanding the internal energy flow -- including the metabolism -- of large ocean creatures like sharks and rays could be key to their survival in a changing climate, according to a new study. Researchers investigating the bioenergetics of sharks and rays; data which may reveal how they will fare in a drastically changing ocean.

'Is it time for another contraception revolution?'

Science Daily: Climate News - Thu, 08/01/2019 - 00:17
In an effort to protect the planet and preserve its natural treasures for future generations, another contraception revolution that provides options for populations not currently being served by modern contraception may be the answer according to the author of a new article.

Krypton reveals ancient water beneath the Israeli desert

Science Daily: Climate News - Wed, 07/31/2019 - 19:54
Getting reliable precipitation data from the past has proven difficult, as is predicting regional changes for climate models in the present. A combination of isotope techniques may help resolve both.

Animal friendships 'change with the weather' in the Masai Mara

Science Daily: Climate News - Wed, 07/31/2019 - 19:54
When it comes to choosing which other species to hang out with, wild animals quite literally change their minds with the weather, a new study reveals. The findings could help conservationists better predict the risk of extinction faced by endangered species.

Poisonous grasses and livestock

Science Daily: Climate News - Wed, 07/31/2019 - 18:29
Stories of mass poisoning incidents of livestock due to toxic grasses made headlines especially overseas. Animal ecologists have studied whether this hazard is also lurking on German pastures.

Warmer winters could lead to longer blue crab season in Chesapeake Bay

Science Daily: Climate News - Wed, 07/31/2019 - 17:22
Scientists are predicting that warmer winters in the Chesapeake Bay will likely lead to longer and more productive seasons for Maryland's favorite summer crustacean, the blue crab.

Climate change alters tree demography in northern forests

Science Daily: Climate News - Wed, 07/31/2019 - 17:21
The rise in temperature and precipitation levels in summer in northern Japan has negatively affected the growth of conifers and resulted in their gradual decline, according to a 38-year-long study in which mixed forests of conifers and broad-leaved trees were monitored.

West Coast forest landowners will plant less Douglas-fir in warming climate, model shows

Science Daily: Climate News - Tue, 07/30/2019 - 21:18
West Coast forest landowners are expected to adapt to climate change by gradually switching from Douglas-fir to other types of trees such as hardwoods and ponderosa pine.

Non-lethal impacts of seabirds' plastic ingestion

Science Daily: Climate News - Tue, 07/30/2019 - 16:26
A new study of seabirds that had ingested plastic debris has revealed a range of non-lethal impacts on their health and physiology. While seabird deaths due to swallowing plastic debris or becoming entangled in it have received global attention, the non-lethal effects on seabirds that survive plastic ingestion are less well-known.

Whole-tree harvesting could boost biomass production

Science Daily: Climate News - Mon, 07/29/2019 - 22:23
Making the shift to renewable energy sources requires biomass, too.

African smoke is fertilizing Amazon rainforest and oceans

Science Daily: Climate News - Mon, 07/29/2019 - 22:18
A new study found that smoke from fires in Africa may be the most important source of a key nutrient -- phosphorus -- that acts as a fertilizer in the Amazon rainforest, Tropical Atlantic and Southern oceans.

Improved estimates of Brazilian Amazon gains and losses

Science Daily: Climate News - Mon, 07/29/2019 - 19:38
A new study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate and other human activities have resulted in substantial deforestation in the Brazilian Amazon over the past several decades.
