The Warming ‘Hole’ Myth
Non-Warming Regions Are More Rule Than Exception
Earlier this month, the authors of a new paper (Partridge et al., 2018) published in Geophysical Research Letters promulgated the term “warming hole” to describe the cooling temperatures gripping most of the Eastern half of the United States from the late 1950s through 2015

I missed this report at the time, but it is a comprehensive account of how large scale adjustments of temperatures have made global temperature datasets virtually worthless. (…)

A new scientific study says surface temperatures in the Northeastern U.S. (Appalachian Mountains) have undergone a significant long-term cooling trend since the early 20th century, complicating the detection of a clear anthropogenic global warming (AGW) signal for the region.
According to Eck (2018), the two coldest Appalachian winters since 1910 were recorded in recent years (2009-’10 and 2010-’11), and 9 of the 10 warmest winters occurred prior to 1960.
In the early 1930s, Appalachian winters were 4.7°C warmer than they have been during the last 30 years (1987-2017).

There is a footnote to yesterday’s story about the huge adjustments made by NOAA to the temperature record in NY State.
Recall the Jan 2018 temperatures for the three stations we looked at, as derived from the actual station data: (…)

A recently highlighted paper published by atmospheric scientists Scafetta et al., (2017) featured a graph (above) documenting post-2000 trends in the published estimates of the Earth’s climate sensitivity to a doubling of CO2 concentrations (from 280 parts per million to 560 ppm).

Prologue: I have been writing recently about Sea Level Rise, both as particular local examples ( Guam, Canton, Miami, New York, and NY/NJ ) and in the series SEA LEVEL: Rise and Fall, of which this is the fourth-plus installment.
In Part 4, I showed how one gets a rise out of nothing, a neat trick performed by Nerem et al. That’s R. Steven Nerem, of the CU Sea Level Research Group. The blinking image is the summary of that essay.

When the seabed loses its stability and starts to move, it often happens in much larger dimensions than landslides ashore — and at slopes with very low gradients. At the same time, discplacement of large amounts of sediment under water scan cause devastating tsunamis. However, why and when submarine landslides develop is hardly understood. Marine scientists have now published possible causes based on observations on submarine landslides off the coast of northwest Africa.

GEOMAR researchers find links between sedimentation and methane seeps on the seafloor off the coast of Norway
Large amounts of the greenhouse gas methane are locked up as solid gas hydrates in the continental slopes of ocean margins. Their stability depends on low temperatures and high pressure. However, other factors that influence gas hydrate stability are not as well understood. A German-Norwegian research team has found evidence off the coast of Norway that the amount of sediment deposited on the seafloor can play a crucial role. The study has been published today in the international journal Nature Communications.
