World-wide carbon dioxide hits new high: 404 parts-per-million (ppm)
April 21, 2015 10:29 AM
Our inexorable march towards ruining the planet continues:
Weekly carbon dioxide measurements from the pristine air atop Hawaii's Mauna Loa have just topped another predictable yet worrisome milestone: 404 parts per million. By all evidence, we now have the largest amount of CO2 present in Earth's atmosphere for at least the last 800,000 years, and probably several million. The most prevalent of the human-produced greenhouse gases, carbon dioxide has been measured regularly by scientists at Mauna Loa since 1958. The gas is also measured at other sites around the world, but the Mauna Loa dataset is the most widely tracked index of global trends because of its uninterrupted 57-year length.
We. Are. Doomed.
More accurately: billions of humans in less-developed nations are doomed. Most Americans will survive, although our great-grandchildren's standard of living is sure to suffer. First-world problems; undeveloped countries' nightmares.
Arctic Ice and Pacific Tycoons.

Mother Earth is changing rapidly.
The Arctic Ice cover is shrinking at alarming rates:
On February 25, 2015, Arctic sea ice extent appeared to have reached its annual maximum extent, marking the beginning of the sea ice melt season. This year's maximum extent not only occurred early; it is also the lowest in the satellite record.The reasons are complicated, but we're given an idea that it all originated in the Pacific with it's above normal temperatures causing massive storms to flow northward:
February was characterized by an unusual configuration of the jet stream, leading to warm conditions over the Pacific side of the Arctic that maintained low sea ice extent in the Bering Sea and the Sea of Okhotsk. Furthermore, since the last half of February through the middle of March, the Arctic Oscillation was in a strongly positive phase, with index values exceeding 5.0 for several days in the first week of March. This has been expressed as a strong Icelandic Low, a semi-permanent area of low atmospheric pressure found between Iceland and southern Greenland and extending into the Barents Sea. The strong Icelandic Low led to a pattern of surface winds over the Barents and Kara seas with an unusually strong component from the south.
Perhaps it's all caused by these massive storms, which seem to come one right after the other recently:
