Ocean level rise is known as one of the most disquieting effects of global warming, with more than three billion people living on the coast or less than 200 kilometres land inward and one tenth of the world population living … Continue reading
A layer of Antarctic Bottom Water colder than 0ºC (Credit: NOAA)
Scientists have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011.
These findings, in a study now online, will likely stimulate new research on the causes of this change.
The U.S. National Research Council has just released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions.
There has been much speculation about what exactly caused the end of the last ice age 10,000 years ago. Some say the Earth’s orbital changes were the cause, others say it was an increase in atmospheric CO2. But although a … Continue reading
That would likely mean that also the official UN climate goal of limiting the average world temperature rise to no more than 2 degrees Celsius – a target linked to 450 ppm CO2 equivalent stabilisation scenarios (practically ambitious, theoretically weak) … Continue reading
If you are interested in sea level rise news, you have a busy week. First we learn from a Nature Climate Change publication that the Greenland ice sheet is already gone. Then earlier today two studies published in Environmental Research … Continue reading
Earth is a bit over 4.5 billion years old. Life on it is only about one billion years younger. And let´s say Homo smartphonensis is a mere three years old.
