And what did these analyses reveal?
Not surprisingly, when all was said and done, the authors report that “increasing [the] CO2 concentration to 3000 ppm at 35°C did not cause changes in any of the measured responses.” They did note, however, that the heart rates of the subjects were slightly reduced under elevated CO2 conditions (Figure 1, top left panel), although these reductions were not statistically significant.

Since 1988, a mere 100 companies have been responsible for 71 percent of the entire world’s industrial greenhouse gas emissions.
This data comes from an inaugural report published by the Carbon Disclosure Project (CDP), an environmental non-profit. Charting the rapid expansion of the fossil fuel industry in the last 28 years, they have now released some truly staggering numbers on the world’s major carbon polluters.

J’ai eu l’immense honneur et le plaisir de côtoyer à de multiples reprises le Professeur Istvàn Marko.
C’était vraiment une personnalité exceptionnelle, tant sur le plan humain que scientifique. Sa disparition inopinée laisse un vide profond, et un grand désarroi parmi ceux qui l’ont connu

Today ‘warm’ is strongly connected with ‘climate change’, if not with ‘dangerous climate change’. In the minds of people ‘cold’ should be more stable. But, paleo data show that it is‘cold’ that is unstable. While ‘warm’ always shows a high stability in climatic conditions.

Weathering of Earth by glaciers may have warmed the planet over eons by aiding the release of carbon dioxide into the atmosphere. A new study shows the cumulative effect may have created negative feedback that prevented runaway glaciation.

The purpose of this study is to present robust evidence that the sun is working with water vapour to control the Earth’s climate and to show that the influence of CO2 on atmospheric temperature is so small as to be negligible.

The chart below is taken directly from figures provided by the U.S. government’s Carbon Dioxide Information Analysis Center (CDIAC) website, specifically its 2016 Global Carbon Project spreadsheet on the Historical Budget tab. In terms of gigatons of carbon, and from 1770 to 2004, it itemizes the growth rate of radiative forcing by atmospheric CO2 and the growth rate of oceanic absorption, what is known as a “carbon sink.”

Corals have a little thermometer built in them, when you take a core of them from many years ago we know what the temperature of the water was back when Captain Cook sailed up the coast, it was actually about the same temperature then. It was colder 100 years ago, but it has recovered from that. The temperatures on the reef are not even significantly warmer than average on a hundred year timescale.

We present a decadal-centennial scale Holocene climate record based on trace elements contents from a 65 cm stalagmite (“Père Noël”) from Belgian Père Noël cave. Père Noël (PN) stalagmite covers the last 12.7 ka according to U/Th dating. High spatial resolution measurements of trace elements (Sr, Ba, Mg and Al) were done by Laser- Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). Trace elements profiles were interpreted as environmental and climate changes in the Han-sur-Lesse region.

The New York Times said yesterday that heatwaves in the past were “virtually unheard of in the 1950s”, temperatures approaching 130 degrees didn’t used to occur, and summer temperatures have shifted towards more extreme heat.
(…) Every single claim in the article is patently false, and the exact opposite of reality. The authors intentionally started their study in a cold period, after the extreme heat of the 1930’s.

Now that the alarmists have had their day trumpeting the IPCC’s worst case scenario (it’s unlikely and becoming more so), let’s look at their best case scenario (hidden by journalists). The risk probabilities are asymmetric: the good news is more likely than the bad news. This is inspirational, telling people that we can make a better world.

The New York Times’ article breathlessly reports:
“From the 1950s to today, 8.3 billion metric tons of plastic have been produced, with around half of it made since 2004. And since plastic does not naturally degrade, the billions of tons sitting in landfills, floating in the oceans or piling up on city streets will provide a marker if later civilizations ever want to classify our era. Perhaps they will call this time on Earth the Plastocene Epoch.”

About half of the CO2 emitted by man gets absorbed by the oceans and so does not stay in the atmosphere. Here there are certain areas of the ocean that are especially efficient CO2 sinks, while others do not absorb so well. What follows is a look of the newest literature on the subject.

That’s right, according to NASA, sea levels are going DOWN! This is big news. How come the media hasn’t mentioned it?
NASA satellite sea level observations for the past 24 years show that – on average – sea levels have been rising 3.4 millimeters per year. That’s 0.134 inches, about the thickness of a dime and a nickel stacked together, per year.

The hidden consequences of a massive use of intermittent renewable energy systems for electricity production are highlighted, using existing electricity production data from Germany from the last 5 years, where presently a system is in operation with an installed capacity of about 50 GW in wind turbines (sum of onshore and offshore wind) and 40GW in photovoltaic panels.This fleet of intermittent renewable systems produces more than half of the yearly renewable electrical energy of Germany, the rest being produced by hydro, so-called ‘biomass’ and a very small fraction of geothermal sources

U.S. evolves into coal, gas and oil global energy giant supplying world’s hungry energy markets
David Middleton’s excellent WUWT article addressing the resurgence of the American coal industry as well as the growing role of U.S. natural gas production in creating global gas export markets hits the nail on the head in demonstrating how dominant the U.S. has become in producing and supplying global energy markets at home and abroad with growing demands for fossil fuels.
The IEA agency clearly recognizes the U.S. as the global driver of a huge transformation of the world’s natural gas energy markets.

US wins, Middle East loses
While US scores with increased rig count and production, the oil industry in the Middle-East is festering with under investment. Said to be in trillions, the lack of investment could boomerang as supply deficit within a decade. Let’s not forget that oil exploration is a long term development in which a decade is but short. Why are the investors moving away?

I’ve looked at UK sea level rise, but what about global?
As you can see, the rate of rise was very similar between roughly 1930 to 1960, as it has been since 1990. We see the same pattern at UK sites.
David’s graph mirrors that of the original paper. As with most sources of sea level data, the scale is set to make the rise appear to be astronomic.
Given that the IPCC is forecasting a rise of a meter and more by 2100, a more appropriate scale would look like this …

In the Bay of Naples, Europe’s most notorious giant is showing signs of reawakening from its long slumber.
Campi Flegrei, a name that aptly translates as “burning fields”, is a supervolcano. It consists of a vast and complex network of underground chambers that formed hundreds of thousands of years ago, stretching from the outskirts of Naples to underneath the Mediterranean Sea. About half a million people live in Campi Flegrei’s seven-mile-long caldera, which was formed by vast eruptions 200,000, 39,000, 35,000 and 12,000 years ago.

Weinberg advised OPEC to change tack and go back to what it set out to do initially: stifle U.S. shale by pumping at maximum. “They should let prices crash to kill shale and then aim for steady price increases in the long term,” Weinstein told Bloomberg. The question remains, however, whether OPEC, with oil-reliant budgets already strained, could afford this tactic reversal now that they’ve suffered price lows for an extended period of time.
