Ole Humlum, Professor of Physical Geography, University of Oslo, Norway: According to the instrumental temperature record (since about 1850), 2019 was a very warm year, but cooler than 2016. Since 2004, when detailed recording of ocean temperatures began, the global oceans above 1900 m depth have, on average, warmed somewhat. Since 1972, however, snow extent has been largely stable. Data from tide gauges all over the world suggest an average global sea-level rise of 1–1.5 mm/year, while the satellite record suggests a rise of about 3.2 mm/year, or more. The noticeable difference in rate (a ratio of at least 1:2) between the two data sets still has no broadly accepted explanation. The focus in this report is on observations, and not on output from numerical models.
Gregory Wrightstone, geologist has been investigating the Earth’s processes for more than 35 years. He is author of the newly published book Inconvenient Facts: An article highly critical of my book Inconvenient Facts, a bestseller, has received wide distribution. It’s Easy to be Tricked by a Climate Denier purports to be a factual take-down of the book and, by extension, of me. However, it is really just one more example of how proponents of catastrophic man-made warming need to resort to lies and distortion in order to advance their agenda.
Guus Berkhout, physicist, electrical engineer, founder of Netherlands based Climate Intelligence Foundation (CLINTEL): Letter to the Secretary-General of the United Nations. There is no climate emergency. A global network of 500 scientists and professionals has prepared this urgent message. Climate science should be less political, while climate policies should be more scientific. The aim of international policy should be to provide reliable and affordable energy at all times, and throughout the world.
H J Schellnhuber, Chief Government Advisor, Potsdam Institute for Climate Impact Research (PIK):. The German government tells their citizens if they cut back on use of fossil fuels and nuclear, Germany will be able to control Earth's climate. A while ago, a German auto maker had trouble reporting exhaust gases from the cars. Now, PIK claims their advice on use of fossil fuels and nuclear power will enable Germany to control Earth's climate. Wahnsinn - crazy. Schwachsinn - idiocy.
