Beijing sinking by four inches a year

Beijing is sinking due to the excessive pumping of groundwater, scientists have warned. The city sits on extensive natural reservoirs of water that are drying out through human use, causing areas to subside. The team behind the research, which used satellite imagery for its findings, say the city's central Chaoyang business district is among the worst-affected areas, subsiding at four inches a year.

Study shows ARGO ocean robots uncertainty was up to 100 times larger than advertised

The Hadfield study compared the new ARGO robotic buoys to other ways of measuring ocean temperatures in a slice across the North Atlantic. The results are fairly devastating for claims that the oceans are heating by 0.005° C per year. Hadfield et al found that the Argo network made errors around 0.5° C, and up to 2° C in one area.

The Atlantic Is Entering A Cool Phase That Will Change The World’s Weather

The Atlantic Ocean’s surface temperature swings between warm and cold phases every few decades. Like its higher-frequency Pacific relative El Nino, this so-called “Atlantic Multidecadal Oscillation” can alter weather patterns throughout the world. The warmer spell we’ve seen since the late 1990s has generally meant warmer conditions in Ireland and Britain, more North Atlantic hurricanes, and worse droughts in the US Midwest.

However a colder phase in the Atlantic could bring drought and consequent famine to the developing countries of Africa’s Sahel region. In the UK it would offer a brief respite from the rise of global temperatures, while less rainfall would mean more frequent summer barbeques. A cold Atlantic also means fewer hurricanes hitting the southern US.

not sinking after all
Turns out the growth of Islands exceeds the rate of sea rise.

Updated NASA Data: Global Warming Not Causing Any Polar Ice Retreat

Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in 1979. Since the end of 2012, moreover, total polar ice extent has largely remained above the post-1979 average. The updated data contradict one of the most frequently asserted global warming claims – that global warming is causing the polar ice caps to recede.

Global sea levels are rising faster than previously thought

According to the GRACE gravitational-recovery satellites, sea level actually fell from 2003-2008; According to the ENVISAT sea-level satellite, sea level rose from 2004-2012 at a mean rate equivalent to just 1.3 inches per century; The inter-calibration errors between the series of laser-altimetry satellites from which the “official” sea-level record is obtained are greater than the sea level rise they purport to show. Tide gauges and benchmarks show very little sea level rise. And why should there be much sea-level rise? The ARGO bathythermographs show that in the first 11 years of the record, 2004-2014, the ocean to a depth of 1900 m warmed at a rate equivalent to 0.23 Cº per century.

cooling

The most accurate readings so far show that the oceans are cooling, not warming.

A recently published estimate of Earth’s global warming trend is 0.63 ± 0.28 W/m2, as calculated from ocean heat content anomaly data spanning 1993-2008. This value is not representative of the recent (2003-2008) warming/cooling rate because of a “flattening” that occurred around 2001-2002. Using only 2003-2008 data from Argo floats, we find by four different algorithms that the recent trend ranges from –0.010 to –0.161 W/m2 with a typical error bar of ±0.2 W/m2. These results fail to support the existence of a frequently-cited large positive computed radiative imbalance.


The land is sinking far faster than the sea is rising. Here is a good article explaining the land is sinking which makes it look like the sea is rising abnormally. It isn't, of course.

It's baaaaaaack

After a record melt season, an Arctic cyclone, and a fascinating fracturing event, Arctic sea ice has reached its maximum extent for the year.
