Alaska: Volunteers left alone save a 6-meter killer whale

In Alaska, a volunteer left, completely left alone, is thrilled to make an extraordinary and almost miraculous goal: they saved a 6-meter orca. The orca managed to return to the sea after six hours. The cries of the orca managed to attract the attention of Chance Strickland, the captain of a private yacht.

He and his crew began to spray water on the animal: the NOAA, warned of the incident, came to the rescue of the crew of the yacht and the orca, until the tide came out and the orca returned in offshore. Tara Neilson posted photos of the rescuers on Twitter, which you can see below.

Greenland loses 8 billion tons of ice per day

Greenland ice sheet began summer is accelerating melting with the arrival of summer and temperatures far above the average of the period.

Since 2000 there has been an increase in the speed and amount of ice lost from the ice sheet. In 2019, the melting of the ice released 600 billion tons of water, with a rise of 1.5 millimeters in sea level. Now, just in 2021, the heat wave with temperatures over 10 degrees above average has led the Greenland ice sheet to lose eight billion tons of ice per day.

Danish experts and scientists, such as Jason Box of the National Geological Survey of Denmark and Greenland, said: "Although the start of the ablation season was late this year, our data shows that the melting was quite intense on the ice sheet glacial since June.

And with a relatively dry winter we risk experiencing very high ice loss this year, at the start of 2019, if we encounter another heat spike, and sea level is currently rising at a rate of about 4 mm per year. More than half of this comes from melting glaciers and ice sheets.

A new scientific study shows that the rate at which the latter are losing ice is in the high range than predicted by climate models in the last major IPCC report. Even exceeding what is predicted by climate models with current greenhouse gas emissions.

The reasons for this are different in Greenland and in Antarctica, and this highlights the need to work to understand the phenomenon."
