Climate change will decimate Palm Springs, Coachella Valley tourism

Tue, 09/08/2020 - 18:33
A new study finds that climate change will have a devastating effect on the greater Palm Springs area's dominant industry -- tourism. Due to climate change, the number of days above 85 degrees between November and April is projected to increase up to 150% by the end of the century.

Ancient hunters stayed in frozen Northern Europe rather than migrating to warmer areas, evidence from Arctic fox bones shows

Tue, 09/08/2020 - 17:16
Ancient hunters stayed in the coldest part of Northern Europe rather than migrating to escape freezing winter conditions, archaeologists have found.

A difficult year for forests, fields and meadows

Tue, 09/08/2020 - 16:37
The warm, dry summer of 2018 has left clear traces in various ecosystems. Researchers have found that if the climate continues to warm up, higher altitudes can also expect negative consequences in the future.

Changing what we eat could offset years of climate-warming emissions

Mon, 09/07/2020 - 18:23
Plant protein foods -- like lentils, beans, and nuts --c an provide vital nutrients using a small fraction of the land required to produce meat and dairy. By shifting to these foods, much of the remaining land could support ecosystems that absorb CO2, according to a new study.

Multinationals' supply chains account for a fifth of global emissions

Mon, 09/07/2020 - 18:23
A fifth of carbon dioxide emissions come from multinational companies' global supply chains, according to a new study that shows the scope of multinationals' influence on climate change.

'Wrong-way' migrations stop shellfish from escaping ocean warming

Mon, 09/07/2020 - 18:23
Ocean warming is paradoxically driving bottom-dwelling invertebrates -- including sea scallops, blue mussels, surfclams and quahogs that are valuable to the shellfish industry -- into warmer waters and threatening their survival, a new study shows.

Plant protein discovery could reduce need for fertilizer

Fri, 09/04/2020 - 19:13
Researchers have discovered how a protein in plant roots controls the uptake of minerals and water, a finding which could improve the tolerance of agricultural crops to climate change and reduce the need for chemical fertilizers.

Pollination: Air pollution renders flower odors unattractive to moths

Fri, 09/04/2020 - 17:18
Researchers showed that tobacco hawkmoths lost attraction to the scent of their preferred flowers when that scent had been altered by ozone. This oxidizing pollutant thus disturbs the chemical communication between a plant and its pollinator. However, when given the chance, hawkmoths quickly learn that an unpleasantly polluted scent may lead to nutritious nectar.

Ocean carbon uptake widely underestimated

Fri, 09/04/2020 - 16:03
The world's oceans soak up more carbon than most scientific models suggest, according to new research.

New mathematical method shows how climate change led to fall of ancient civilization

Thu, 09/03/2020 - 17:56
A researcher developed a mathematical method that shows climate change likely caused the rise and fall of an ancient civilization. A new article outlines the technique he developed and shows how shifting monsoon patterns led to the demise of the Indus Valley Civilization, a Bronze Age civilization contemporary to Mesopotamia and ancient Egypt.

Gravity wave insights from internet-beaming balloons

Thu, 09/03/2020 - 01:24
A better understanding of how gravity waves in the upper atmosphere interact with the jet stream, polar vortex and other phenomena could be key to improved weather predictions and climate models.

Many forests scorched by wildfire won't bounce back

Thu, 09/03/2020 - 01:24
A study of 22 burned areas across the Southern Rocky Mountains found that forests are becoming less resilient to fire, with some converting to grasslands after burning. By 2050, as little as 3.5% to 6.3% of Douglas fir and ponderosa pine forests in the region will be suitable for recovery post-fire, the study found.

Has Earth's oxygen rusted the Moon for billions of years?

Wed, 09/02/2020 - 22:21
To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon.

Bering Sea ice extent is at most reduced state in last 5,500 years

Wed, 09/02/2020 - 22:21
Through the analysis of vegetation from a Bering Sea island, researchers have determined that the extent of sea ice in the region is lower than it's been for thousands of years.

Globalization is reweaving the web of life

Wed, 09/02/2020 - 18:44
Networks of interactions among species are becoming increasingly similar across ecosystems, according to a global analysis. Data collected over the last 75 years show the accelerating pace that introduced species are reshaping mutualistic relationships and creating new ecological links between previously disconnected ecosystems. These changes to mutualistic networks will influence which species are winners and losers in future ecosystems and may expose ecological networks to collapse.

Great Barrier Reef 'glue' at risk from ocean acidification

Wed, 09/02/2020 - 16:51
Scientists have suspected that increasing ocean acidity would weaken and thin the structures underpinning tropical reefs. Now they have irrefutable evidence dating back 30,000 years.

Biodiversity: In a mite-y bit of trouble

Wed, 09/02/2020 - 16:51
Mite extinctions are occurring at least 1,000 times the 'natural' rate - a finding a researcher says is another warning that global biodiversity is in deep trouble. The 1.25 million mite species around the planet occupy an enormous variety of terrestrial and freshwater ecosystems, from the equator, to polar regions and high altitude areas.

Common species mirror rare animals' response to global change

Wed, 09/02/2020 - 15:23
A study of more than 2,000 species reveals animal populations around the world - from the very common to endangered species - are going up and down as global change alters land, sea and freshwater ecosystems.

Climate change could increase rice yields

Wed, 09/02/2020 - 15:23
Research reveals how rice ratooning practices can help Japanese farmers increase rice yields.

Viruses could be harder to kill after adapting to warm environments

Wed, 09/02/2020 - 15:23
Enteroviruses and other pathogenic viruses that make their way into surface waters can be inactivated by heat, sunshine and other microbes, thereby reducing their ability to spread disease. But researchers report that global warming could cause viruses to evolve, rendering them less susceptible to these and other disinfectants, such as chlorine.
