Study: climate change accelerates growth in trees, especially urban ones

by  TECHNICAL UNIVERSITY OF MUNICH, November 14, 2017 in WUWT


While the effects of climate change on tree growth in forests have been extensively studied, there is little information available so far for urban trees”, said Professor Hans Pretzsch from the Chair for Forest Growth and Yield Science at TUM. The study supported by the Bavarian State Ministry for Environment and Consumer Protection as well as by the Audi Foundation for the Environment, which was published in the journal Scientific Reports, for the first time systematically examined the growth of urban trees worldwide for trends resulting from changing environmental conditions.

Israeli Astrophysicist rejects UN IPCC – Finds ‘the sun completely overturns the way we should see global warming’

by Dr. Shaviv, November 9, 2017 in ClimateDepot


(…)The body of evidence however clearly shows that the climate sensitivity is on the low side, about 1 to 1.5 degree increase per CO2 doubling. People in the climate community are scratching their heads trying to understand the so called hiatus in the warming. Where is the heat hiding? While in reality it simply points to a low sensitivity.

2017 GLOBAL TEMPERATURE: TOO EARLY TO TELL

by Dr David Whitehouse, November 7, 2017 in GWPF


It is far too early to judge this year’s global temperature developments and their significance regarding the long-term warming trend.

The United Nations climate change conference, held in Bonn this year, is always the cue for press releases from the World Meteorological Office and the UK Met Office in which they give their assessment of the year based on 9-10 months of data.

Dealing with the El Nino of recent years (and don’t forget the ‘Pacific Blob’ before that) they have had difficulty with explaining what part of the record temperature was due to El Nino and natural, and what was anthropogenic.

Freeman Dyson on ‘heretical’ thoughts about global warmimg

by Freeman Dyson, November 10, 2017 in WUWT FREEMAN DYSON is professor of physics at the Institute for Advanced Study, in Princeton. His professional interests are in mathematics and astronomy


My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak.

But I have studied the climate models and I know what they can do.

New Literature Strongly Suggests CO2 Residence Time In The Atmosphere Is Exaggerated!

by Dr S. Lüning and Prof. F. Vahrenholt, March 26, 2017,  in NoTricksZone


In addition, we consider temperature dependent natural emission and absorption rates, by which the paleoclimatic CO2 variations and the actual CO2 growth rate can well be explained. The anthropogenic contribution to the actual CO2concentration is found to be 4.3%, its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.”

Most Modern Warming, Including For Recent Decades, Is Due To Solar Forcing, Not CO2

by Kenneth Richard, November 9, 2017 in NoTricksZone


Though advocates of the dangerous anthropogenic global warming (AGW) narrative may not welcome the news, evidence that modern day global warming has largely been driven by natural factors – especially solar activity – continues to pile up.

Much of the debate about the Sun’s role in climate change is centered around reconstructions of solar activity that span the last 400 years, which now include satellite data from the late 1970s to present.

Hot News from the Antarctic Underground

Study Bolsters Theory of Heat Source Under West Antarctica

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica’s Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet. Although the heat source isn’t a new or increasing threat to the West Antarctic ice sheet, it may help explain why the ice sheet collapsed rapidly in an earlier era of rapid climate change, and why it is so unstable today.

Oceans driving warming this century, same as in 1930s

by Ron Clutz, November 8, 2017, in ClimateChangeDispatch


The graph [after the jump] is noisy, but the density is needed to see the seasonal patterns in the oceanic fluctuations. Previous posts focused on the rise and fall of the last El Nino starting in 2015.

This post takes a longer view, encompassing the significant 1998 El Nino and since. The color schemes are retained for Global, Tropics, NH and SH anomalies. 

Despite the long time frame, I have kept the monthly data (rather than yearly averages) because of interesting shifts between January and July.

NOAA’s USCRN Revisited – no significant warming in the USA in 12 years

by Willis Eschenbach, November 8, 2017, in WUWT


Back in 2014, Anthony put up a post called “NOAA shows ‘the pause’ in the U.S. surface temperature record over nearly a decade“. In it, he discussed the record of the US Climate Reference Network (USCRN). I can’t better Anthony’s description of the USCRN, so I’m stealing it to use here: (…)
