Paradoxically, extreme cold spells could become more frequent as the Arctic warms along with the rest of the planet. — February 2, 2019

Paradoxically, extreme cold spells could become more frequent as the Arctic warms along with the rest of the planet.

“The polar vortex is a low-pressure mass of cold air that swirls perpetually above Earth’s polar regions. There’s one in the Northern Hemisphere — the one responsible for the recent cold spell across the U.S. — and another in the Southern Hemisphere.

It’s normal for the Arctic polar vortex to expand in winter, bringing colder air to lower latitudes. But sometimes the polar vortex weakens, and the fast-moving current of air known as the Jet stream shifts, allowing the vortex to drift southward to cause unusually cold temperatures in those areas.

“That cold air that was stuck over the Arctic gets moved south, into the actual continental United States,” David Kanter, an assistant professor of environmental studies at New York University, told NBC News in a video interview.

Paradoxically, extreme cold spells could become more frequent as the Arctic warms along with the rest of the planet.

“Arctic warming leads to a weaker jet stream, which leads to more extreme winters,” Kanter said. So the notion that global warming would “rescue” us from cold weather extremes — something President Donald Trump alluded to in a recent tweet — is misguided. As Kanter put it, “We’re going to see more extremes as the climate continues to warm.”

The Aqua satellite has been orbiting Earth since 2002. Its instruments create a global map of atmospheric phenomena, including temperature and humidity, cloud heights and the concentrations of carbon dioxide and the other greenhouse gases that contribute to global warming.”

Satellite Falls To Earth In Fiery Death Dive.  It  Almost Hits Argentina.

A European satellite met its fiery doom in Earth’s atmosphere late Sunday (Nov. 10), succumbing to the same gravitational pull of the planet that it spent the last four years mapping like never before.

The European Space Agency’s GOCE satellite fell from space Sunday at 7 p.m. EST (0000 Nov. 11 GMT) while flying on a path that would take it over Siberia, the Western Pacific Ocean, the eastern Indian Ocean and Antarctica, ESA officials said.  Read more…http://www.huffingtonpost.com/2013/11/11/satellite-falls-earth-death-dive_n_4252796.html#es_share_ended

An uncontrolled fall from space was always to be its fate. They just don’t care. — November 10, 2013

An uncontrolled fall from space was always to be its fate. They just don’t care.

I don’t understand why the European Space Agency and other agencies are allowed to design vehicles, or satellites that after having successfully completed their mission are left to return to Earth in an uncontrolled fall from space.  Is it too difficult to program and include fuel for their controlled return?  Skylab  suffered the same fate and NASA was not too worried about its trajectory as it disintegrated while tumbling through Earth’s atmosphere. Eventually probability will catch up with their recklessness.Unknown

Doomed European Satellite May Fall to Earth Tonight, But Where?

A European satellite at the end of its mission is expected to fall out of space tonight. According to European Space Agency predictions, the falling GOCE satellite could to Earth sometime Sunday night (Nov. 10) or early Monday. “The satellite is at an altitude of 147 km (91 miles), dropping at a rate of more than 1 km (0.6 miles) an hour,” ESA’s GOCE spacecraft operations manager Christoph Steiger wrote in a status update today, adding that the atmospheric drag on the satellite is too high to measure. ESA scientists expect 25 to 45 fragments of the satellite to survive the fiery re-entry through Earth’s atmosphere.

 

Did you wave when our picture was taken from Saturn? — July 23, 2013

Did you wave when our picture was taken from Saturn?

The tiny blue dot in this image is in fact Earth captured from a distance of 900 million miles looking past Saturn’s rings.  Earth is a tiny blue dot in this image taken by the Cassini spacecraft hundreds of millions of miles away.  Hopefully we were all smiling.
