STATE OF THE CLIMATE 2017 - Ole Humlum

In a report by Emeritus Professor of Physical Geography, University of Oslo, Norway - Ole Humlum, published by the Global Warming Policy Foundation (Link pdf) - his findings included:

Air temperatures

Many Arctic regions experienced record high temperatures in 2016, but in 2017 conditions were generally cooler. The Arctic temperature peak in 2016 may have been affected by ocean heat released from the Pacific Ocean during the 2015–16 El Niño and subsequently transported to the Arctic region.

Sea ice

 Both variations had simultaneous minima in 2016, with consequences for the global sea ice extent. A trend in the opposite direction, towards higher ice extent at both poles, appears to have begun during 2017, as was predicted in ‘State of the Climate 2016’.

Snow cover

Considering seasonal changes since 1979, the Northern Hemisphere snow cover autumn extent is slightly increasing, the mid-winter extent is approximately stable, and the spring extent is slightly decreasing. In 2017, the Northern Hemisphere snow cover extent was somewhat higher than in 2016 2016, especially during winter, spring and summer.

Global monthly lower troposphere air temperature since 1979 

Global monthly average lower troposphere temperatures since 1979, representing conditions at about 2 km altitude:
(a) UAH, (b) RSS. The thick lines are the simple running 37-month averages,
approximately corresponding to a running three -year average.

Both satellite records for the lower troposphere temperature clearly show the temperature spike associated with the 2015–16 El Niño, and the subsequent drop towards the level characterising the period before (Figure 3). Comparison of the latest (December 2017) record and the May 2015 record (red) shows that only a few small adjustments have been made to the University of Alabama, Huntsville (UAH) series, while the Remote Sensing Systems (RSS) series was recently subject to a large adjustment towards higher temperatures from 2002 onwards; about +0.1ºC. This adjustment was introduced in 2017.

A warning from the Past.

Part of Dwight D. Eisenhower’s Farewell Address (1961) (link)

“The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present – and is gravely to be regarded. “Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.  

“It is the task of statesmanship to mold, to balance, and to integrate these and other forces, new and old, within the principles of our democratic system – ever aiming toward the supreme goals of our free society. — President Dwight D. Eisenhower, January 17, 1961 

SCIENCE advances fastest when data and conclusions are shared as quickly as possible. Yet it is common practice for medical researchers to hoard results for months or years (link)
