Scientists track giant ocean vortex from space

This natural phenomenon is over 100,000 square miles in area, typically persists for about 200 days per year and is strongly linked to monsoons, but is not well understood.

Researchers have found a new way to use satellites to monitor the Great Whirl, a massive whirlpool the size of Colorado that forms each year off the coast of East Africa, they report in a new study.

Using 23 years of satellite data, the new findings show the Great Whirl is larger and longer-lived than scientists previously thought, reports Phys.org.

At its peak, the giant whirlpool is, on average, 275,000 square kilometers (106,000 square miles) in area and persists for about 200 days out of the year. Watch an animation of the Great Whirl’s evolution here.

Sea level views from SEPP (190309) too superficial to be useful, say experts

This is a critique by Professor Nils-Axel Mörner and two colleagues of a recent article discussing problems with IPCC sea level claims.

The original article by Ken Haapala, President, Science and Environmental Policy Project (SEPP) starts:

Rising Seas – At Sea, or Shore? The latest Summary for Policymakers of its full Assessment Report by the UN Intergovernmental Panel for Climate Change (IPCC, AR-5, SPM, 2014) declared that sea level rise is accelerating.

Numerous studies have come out in support of that view. As shown in the 2008 report of the Nongovernment International Panel for Climate Change (NIPCC, 2008), with the ending of the last Ice Age about 18,000 to 20,000 years ago, sea levels have risen about 400 feet (120 meters).

At first, the rise was slow, then rapid, then for the past several thousand years slowing to about 7 to 8 inches (18 to 20 cm) per century. There is some question about the variation during the Little Ice Age and the period following it called the industrial period since 1850.

A laser in space to measure changes in polar ice

The reporter here is obviously sold on endless warming of planet Earth, but ignoring the propaganda, there are some technical details of the mission which is due to last three years but could be extended up to ten. NASA says: ‘The ICESat-2 laser will pulse 10,000 times a second; each pulse will release about 20 trillion photons. Only about a dozen photons hit Earth’s surface and return to the satellite.’

NASA is poised to launch Saturday its most advanced space laser ever, ICESat-2, a $1 billion dollar mission to reveal the depths of the Earth’s melting ice as the climate warms, says Phys.org.

The half-ton satellite, about the size of a smart-car, is scheduled to blast off atop a Delta II rocket on September 15 from Vandenberg Air Force Base in California.

Harry Wexler: Father of weather satellites

These are extracts from an ESA article. In 1954 British science-fiction writer, Arthur C. Clarke wrote to Wexler promoting satellite ideas. In 1960 after years of work and lobbying the first weather satellite was launched.

Wexler was a man of vision, ready to face danger and to give his all to collecting useful data.

He was the first scientist to deliberately fly into a hurricane and also participated in polar expeditions.

His was the mind behind the very first meteorology satellite and even before it reached orbit, he was already dreaming of a global network of satellites to watch the weather worldwide.
. . .
[He] gained a PhD in meteorology from the Massachusetts Institute of Technology in 1939.

First satellite to measure global winds set for launch

Good luck to the mission. A somewhat optimistic claim made here is that this will ‘improve our understanding of manmade climate change’ but, as the report states without noting any irony, the name of the mission is drawn from mythology.

A satellite designed to measure Earth’s global wind patterns is set to be hoisted into orbit Tuesday from the Arianespace launch site in French Guiana, reports Phys.org.

The European Space Agency’s (ESA) Aeolus mission—named for the guardian of wind in Greek mythology—promises to improve short-term weather forecasting and our understanding of manmade climate change.

NASA’s GOLD mission continues despite launch anomaly

The GOLD mission to learn more about the Earth’s ionosphere ran into comms problems after launch yesterday and may take longer than expected to reach its required orbit height. NASA’s own publicity says: “Just like an infrared camera allows you to see how temperatures change with different colors, GOLD images ultraviolet light to provide a map of the Earth that reveals how temperature and atmospheric composition change by location”.

NASA has reported that despite a glitch within minutes of its GOLD mission launch, the satellite is communicating with control systems, reports the Indian Express.

The aim of the Global-scale Observations of the Limb and Disk, or GOLD, mission is to study the dynamic region where space and Earth’s uppermost atmosphere meet.

Study: satellites show no acceleration in global warming for 23 years

‘Official’ climate science response: claim satellite data is not reliable, and play shoot-the-messenger. Predictable, as the results obviously don’t fit theories of man-made warming.

Global warming has not accelerated temperature rise in the bulk atmosphere in more than two decades, according to a new study funded by the Department of Energy.

University of Alabama-Huntsville climate scientists John Christy and Richard McNider found that by removing the climate effects of volcanic eruptions early on in the satellite temperature record showed virtually no change in the rate of warming since the early 1990s.

“We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere’s sensitivity to CO2 much too high,” Christy said in a statement. “This recent paper bolsters that conclusion.”

NASA admits it hasn’t been accurately measuring Earth’s radiation balance

In order to measure Earth’s radiation balance, accurate measurements of both incoming and outgoing radiation have to be made. NASA has been testing a new prototype satellite to measure outgoing radiation from Earth. Up until now, the error on this measurement is estimated to be around +/- 5Wm^2, which means any ‘global warming’ signal is lost in the error margin. This has meant scientists have had to rely on models for estimates.

Tony Heller: Is the global temperature record credible?

Tony Heller, AKA Steve Goddard, has this new video up on youtube. It raises important questions about the way the global temperature record has changed over time.
