Climate cycles and their extrapolation into the future
by Dr. Dietrich Koelle, February 2, 2015 in NoTricksZone
As the reconstruction of the climate’s development in the past by proxy data shows, there’s a series of temperature cycles that appear to be unknown, or ignored by many climate scientists. Among these are the larger climate cycles of 150 million to 180 million years (see Part 1 and Part 2), but also the shorter and for us the more important following cycles:
1000 years (900-1100) Suess cycle with +/- 0.65°C
230 years (230-250) deVries cycle with +/- 0.30°C
65 years (60-65) Ocean cycles with +/- 0.25°C
Large Canadian Arctic climate change study cancelled due to climate change
by University of Manitoba, June 13, 2017 in ScienceDaily
This regrettably postpones the much-anticipated Hudson Bay System Study (BaySys) involving 40 scientists from five universities across Canada. Timing was key for this $17 million, four-year, University of Manitoba-led project.

Winning climate strategy demands details
by Michigan State University, June 12, 2017 in ScienceDaily
Scientists at Michigan State University (MSU) show that examining the daily minutia of climate, not just temperature, but also sunshine, precipitation and soil moisture simultaneously all over a country gives a better understanding of how variable a land’s climate can be. That information is crucial when countries are setting policies aimed at growing food, protecting water supplies and the environment and stemming disease outbreaks. The findings were reported in this week’s Scientific Reports.

HIATUS STUDIES DRIVE CLIMATE RESEARCH
by David Whitehouse, June 2, 2017, in GWPF
The reduction in global temperature after the recent El Nino continues though not as swiftly as some predicted. The next few months will be interesting to see if it returns to levels seen before the recent El Nino took place when global annual average temperatures changed little for at least 15 years.
End Game of Climate Wars: Clive James discusses how it plays out (slowly)
by JoNova, 2017
The best way to kill off the Climate Debate is to do what Team-Alarm has done for years — stop talking about whether it’s real, and just project forwards, detailing the collapse. For twenty years others have been saying “the debate is over”. Now the tables are turning. The debate really is over, skeptics won, and what’s left is to watch it continue to unravel. Clive James argues that it won’t collapse like a house of cards… (an extract from the new IPA book Climate Change: The Facts 2017.)

Indirect Effects of the Sun on Earth’s Climate
by Mike Jonas, June 10, 2017 in WUWT
In this article, I explore the scientific literature on possible solar indirect effects on climate, and suggest a reasonable way of looking at them. This should also answer Leif Svalgaard’s question, though it seems rather unlikely that he would be unaware of any of the material cited here. Certainly just about everything in this article has already appeared on WUWT; the aim here is to present it in a single article (sorry it’s so long). I provide some links to the works of people like Jasper Kirkby, Nir Shaviv and Nigel Calder. For those who have time, those works are worth reading in their entirety.
Ocean Warming Dominates The Increase In Energy Stored In the Climate System
by CO2 is Life, May 13, 2017
The basic physics behind CO2 warming the oceans, and therefore the atmosphere simply don’t exist. The only defined mechanism by which CO2 can affect climate change is by “thermalizing” long-wave infrared radiation between 13 and 18-microns. In reality, there is another one, radiation, but that carries heat away from the earth and results in atmospheric cooling.
A Holocene Temperature Reconstruction Part 4: The global reconstruction
by Andy May, June 9, 2017 in WUWT
In previous posts (here, here and here), we have shown reconstructions for the Antarctic, Southern Hemisphere mid-latitudes, the tropics, the Northern Hemisphere mid-latitudes, and the Arctic. Here we combine them into a simple global temperature reconstruction. The five regional reconstructions are shown in figure 1. The R code to map the proxy locations, the references and metadata for the proxies, and the global reconstruction spreadsheet can be downloaded here

17 New Scientific Papers Dispute CO2 Greenhouse Effect As Primary Explanation For Climate Change
by Kenneth Richard, June 8, 2017 in NoTricksZone
The conventional basic climate model applies “basic physics” to climate, estimating sensitivity to CO2. However, it has two serious architectural errors. It only allows feedbacks in response to surface warming, so it omits the driver-specific feedbacks

NASA Study: Mass Gains of Antarctic Ice Sheet Greater than Losses
by NASA, October 30, 2015
A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.
The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.
According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.
A Holocene Temperature Reconstruction Part 3: The NH and Arctic
by Andy May, June 8, 2017 in WUWT
As we did in the previous two posts, we will examine each proxy and reject any that have an average time step greater than 130 years or if it does not cover at least part of the Little Ice Age (LIA) and the Holocene Climatic Optimum (HCO). We are looking for coverage from 9000 BP to 500 BP or very close to these values. Only simple statistical techniques that are easy to explain will be used.
The Correlation of Seismic Activity and Recent Global Warming
by Arthur Viterito, April 25, 2016 in J. of Earth Sc. & Climatic Change
Earth’s climate is a remarkably “noisy” system, driven by scores of oscillators, feedback mechanisms, and radiative forcings. Amidst all this noise, identifying a solitary input to the system (i.e., HGFA MAG4/6 seismic activity as a proxy for geothermal heat flux) that explains 62% of the variation in the earth’s surface temperature is a significant finding. Additionally, the 1997/1998 SIENA was a strong signal for subsequent global warming, and this type of seismic jump may provide valuable predictive information

Study: ‘Heat island’ effect could double climate change costs for world’s cities
by Anthony Watts, May 30, 2017 in WUWT
From the UNIVERSITY OF SUSSEX and overheated climate science department, comes a claim that just doesn’t seem plausible, suggesting that in the future, nearly 11% of a “worst-off city” gross domestic product would be consumed by UHI boosted climate change. On the other hand, the study is by Dr. Richard Tol, who is well respected by the climate skeptic community. He does have a point about “the effects of uncontrolled urban heat islands”
Overheated cities face climate change costs at least twice as big as the rest of the world because of the ‘urban heat island’ effect, new research shows.
What Happened to Spot? A Solar Update
by Stephanie Osborn, June 7, 2017
I’ve been keeping a spreadsheet since late last summer, and here are the results, as of June 6th, 2017. (Quick and easy data source, the daily sunspot image archives from Solarham.)
This data (through March; I’ve updated it since then) was posted on Jerry Pournelle’s blog a while back, and it elicited several questions from readers, who didn’t understand the information contained therein. So here is an effort to elaborate on the data, for those of you who aren’t astronomers/ astrophysicists and don’t want to have to keep up with all this stuff.
Extreme temperatures in Southeast Asia caused by El Niño and worsened by global warming
by K. Thirumalai et al., June 6, 2017, in Nature Communication
In April 2016, southeast Asia experienced surface air temperatures (SATs) that surpassed national records, exacerbated energy consumption, disrupted agriculture and caused severe human discomfort. Here we show using observations and an ensemble of global warming simulations the combined impact of the El Niño/Southern Oscillation (ENSO) phenomenon and long-term warming on regional SAT extremes. We find a robust relationship between ENSO and southeast Asian SATs wherein virtually all April extremes occur during El Niño years.
A Holocene Temperature Reconstruction Part 2: More reconstructions
by Andy May, June 6, 2017, in WUWT
In the last post (see here) we introduced a new Holocene temperature reconstruction for Antarctica using some of the Marcott, et al. (2013) proxies. In this post, we will present two more reconstructions, one for the Southern Hemisphere mid-latitudes (60°S to 30°S) and another for the tropics (30°S to 30°N)
Solar Update June 2017–the sun is slumping and headed even lower
by David Archibald, June 6, 2017 in WUWT
Solar cycle 24 has seen very low solar activity thus far, likely the lowest in 100 years. The F10.7 flux shows that over the last three and a half years the Sun has gone from solar maximum through a bounded decline to the current stage of the trail to minimum. Solar minimum is likely to be still three years away.
LOL: EU’S CO2 EMISSIONS ON THE RISE, BLAMING COLD WINTER
by Energy Live News, June , 2017 in GWPF
The EU’s total greenhouse gas emissions increased in 2015 for the first time since 2010.
According to new data published by the European Environment Agency (EEA), the 0.5% increase happened largely due to increasing demand for transport – better fuel efficiency in the sector was not enough to offset this.

CLIMATE ALARMISTS WON’T ADMIT THEY ARE WRONG
by Clives James, The Australian in GWPF, June 6, 2017
Actually, a more illustrative starting point for the theme of the permanently imminent climatic apocalypse might be taken as August 3, 1971, when The Sydney Morning Herald announced that the Great Barrier Reef would be dead in six months.
After six months the reef had not died, but it has been going to die almost as soon as that ever since, making it a strangely durable emblem for all those who have wedded themselves to the notion of climate catastrophe.
