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.

A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America.

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
