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.
Greenland, Antarctica Melting Six Times Faster Than in the 1990s
If the current melting trend continues, the regions will be on track to match the “worst-case” scenario of the Intergovernmental Panel on Climate Change (IPCC) of an extra 6.7 inches (17 centimeters) of sea level rise by 2100.
Indigenous knowledge could reveal ways to weather climate change on islands
Some islands have such low elevation, that mere inches of sea-level rise will flood them, but higher, larger islands will also be affected by changes in climate and an understanding of ancient practices in times of climate change might help populations survive, according to researchers.
Mangrove forests protect coastlines. ‘Synthetic mangroves’ could do the same for cities.
To better understand exactly how mangroves can grow in the ocean yet pump freshwater up to their leaves, engineers constructed what they’re dubbing “synthetic mangroves.” The idea for using their wannabe trees: incorporating them into the design of cities to make buildings more resilient in the face of storm surges.
Building sunken breakwaters off SC coast to halt beach erosion has unclear future
The idea — building an underwater barrier to slow down waves, and thus slow the flow of escaping sand — has coastal experts worried about disrupting the coastal flow of sand, nesting sea turtles and worsening water quality on the beach.
