Ocean patterns help scientists forecast drought, water flow in the Colorado river

Ocean patterns help scientists forecast drought, water flow in the Colorado river

Science
Oct. 9 (UPI) -- By analyzing what researchers call "long-term ocean memory," scientists have been able to identify connections between flow rates in the Colorado River and sea surface temperatures in parts of the Pacific and Atlantic oceans. The breakthrough analysis -- described Friday in the journal Communications Earth and Environment -- allowed scientists to develop a forecasting model capable of predicting the Colorado River water supply on multi-year timescales. Advertisement The Colorado River, the most important water resource in the West, is essential to energy production, food and drinking water security, forestry and tourism in California, Arizona, New Mexico, Colorado and Utah. Access to more accurate long-term forecasting models could aid water resource management decisions. ...
Buried lakes of liquid water discovered on Mars

Buried lakes of liquid water discovered on Mars

Science
Three new underground lakes have been detected near the south pole of Mars.Scientists also confirmed the existence of a fourth lake - the presence of which was hinted at in 2018.Liquid water is vital for biology, so the finding will be of interest to researchers studying the potential for life elsewhere in the Solar System.But the lakes are also thought to be extremely salty, which could pose challenges to the survival of any microbial life forms.Billions of years ago, water flowed in rivers and pooled in lakes on the Martian surface. But Mars has since lost much of its atmosphere, which means water can't stay liquid for long on the surface today.However, it's a different matter underground. Is there life floating in the clouds o...
Ocean salinity study reveals amplification of Earth’s water cycle

Ocean salinity study reveals amplification of Earth’s water cycle

Science
Sept. 9 (UPI) -- New analysis of ocean salinity data suggests Earth's water cycle has amplified significantly over the last half-century. The global water cycle has a strong influence on the planet's climate system, and vice versa. As Earth's water cycle changes, so does the climate. To accurately model climate change and its effects on global weather patterns, scientists must understand changes to the planet's water cycle. Advertisement Previous climate models have suggested Earth's water is evaporating at an accelerated pace, a phenomenon that should yield increased precipitation rates across the globe. It's a logical prediction: as Earth gets warmer, more water should become vaporized, triggering the formation of heavier clouds. However, scientists have struggled to confirm such a patt...
Coronavirus: Public told to cut water use amid surge in lockdown demand

Coronavirus: Public told to cut water use amid surge in lockdown demand

Science
Water companies are urging people to use water more carefully during the coronavirus lockdown. They are asking people to avoid hoses and sprinklers, and not to fill paddling pools. However, so far a full hosepipe ban has not been imposed.Companies are responding to a double water whammy from the record dry spring and a surge in demand as people spend more time at home during the lockdown. February this year was the wettest on record and you might have thought the UK had enough H2O - following a drenching winter, rivers and reservoirs were full.But then it barely rained for three subsequent months – another record. Then came coronavirus and lockdown meant people stayed home in the sunshine. May was sunniest UK month on record Water firm 'can't keep up' w...
Climate change: Study pours cold water on oil company net zero claims

Climate change: Study pours cold water on oil company net zero claims

Science
Claims by oil and gas companies that they are curbing their carbon emissions in line with net zero targets are overstated, according to a new review. The independent analysis of six large European corporations acknowledges they have taken big steps on CO2 recently.In April, Shell became the latest to announce ambitious plans to be at net zero for operational emissions by 2050.But the authors say none of the companies are yet aligned with the 1.5C temperature goal. Scientists argue that the global temperature must not rise by more than 1.5C by the end of the century if the world is to avoid the worst impacts of climate change.The research has been carried out by the Transition Pathway Initiative (TPI), an investor-led group whic...
