As sea levels rise, will drinking water supplies be at risk?
The Delaware River, a major source of drinking water for Philadelphia, is facing an emerging threat as rising seas push saltwater farther upstream. It’s a problem that other places, from Miami to Shanghai, will also confront, especially as increasing drought lowers river flows.
Flooding will affect double the number of people worldwide by 2030
The number of people harmed by floods will double worldwide by 2030, according to a new analysis. 147 million people will be hit by floods from rivers and coasts annually by the end of the decade, compared with 72 million people just 10 years ago.
New model to improve accuracy of storm surge analysis
Accurately predicting how many people are at risk due to sea level rise and storm surges has always challenged scientists, but a new method is improving models that account for the impact of these natural occurrences.
Will Florida be lost forever to the climate crisis?
From sea level rise to habitat loss, the effects of the climate crisis are on the verge of making south Florida uninhabitable.
North Pole soon to be ice free in summer
The Arctic Ocean in summer will very likely be ice free before 2050, at least temporarily. The efficacy of climate-protection measures will determine how often and for how long. These are the results of a new research study involving 21 research institutes from around the world.
Eurasian ice sheet collapse raised seas eight metres: study
Ice sheets melting or breaking away as global temperatures rise are subject to what climate scientists term temperature “tipping points”. Many researchers fear that the ice sheets in Greenland and West Antarctica will continue to melt even if warming is slowed as carbon emissions are cut.
US to have major floods on daily basis unless sea-level rise is curbed – study
Flooding events that now occur in America once in a lifetime could become a daily occurrence along the vast majority of the US coastline if sea level rise is not curbed, according to a new study that warns the advancing tides will “radically redefine the coastline of the 21st century”.
Scientists confirm dramatic melting of Greenland ice sheet
There was a dramatic melting of Greenland’s ice sheet in the summer of 2019, researchers have confirmed, in a study that reveals the loss was largely due to a persistent zone of high pressure over the region.
A rapidly changing Arctic
A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift — a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.
