In the last 25,000 years there has been an anti-correlation between rising CO2 and the Siberian Arctic temperature – the opposite of what is claimed by proponents of the anthropogenic global warming narrative. According to a new study, Arctic Siberia was 4°C warmer than it is today from 15,000 to 11,000 years ago, when CO2 […]

A new study exposes the uncertainty in solar activity reconstructions, but suggests solar models explain climate changes far better than atmospheric CO2 concentrations. Proxy model estimates of the impact of solar variability on climate are highly uncertain. For example, estimations of the increase in solar irradiance over the last 400 years range anywhere from 0.75 […]

The global mean surface temperature (GMST) effects of a 1 W/m² radiative forcing, or positive/negative energy imbalance, has been obtained from the observations from the 1991 Mt. Pinatubo eruption. CO2’s climate effects are claimed to be many times larger than observations indicate. The observed climate sensitivity (CS) to a perturbation to Earth’s Energy Imbalance (EEI) […]

Germany’s proposed heating policies will lead to a disaster, experts warn. 45 billion euros will get ZERO CO2 savings! Prof. Gerd Ganteför. Image cropped here. Oil and gas heating to be eliminated, starting next year At first, Germans had the impression that the worst had been averted as far as the planned intervention of the Greens […]

Surface air CO2 concentrations vary by 100s to 1,000s of ppm within a span of hours to days or weeks across the natural world. The observational evidence suggests these variations are neither driving or even causing temperature changes. According to recent field research (Mungai, 2021) conducted in Kenya, the observed CO2 concentrations in the atmospheric […]

The governmental need to portray elevated CO2 as dangerous to humans was recently pitted against the governmental need to require face masks be worn on healthy people. During the height of the COVID-19 pandemic requiring healthy people of all ages to wear face masks in public settings became a common governmental policy – especially in […]

Since the early 1990s the conventional assumption, aligned with modeling, has been that a molecule of human CO2 emission stays in the atmosphere – its residence time – for centuries. This fits the anthropogenic global warming (AGW) narrative. But empirical evidence contradicts these model-based assumptions. Residence time is closer to 5-10 years. In Table 1 […]

Recall how climate activists demand that ordinary citizens, i.e. “useless consumers”, limit their annual CO2 emissions to just a single measly tonne per person. Currently the average CO2 emissions per person in Europe are about 8 tonnes. German government ministries run by the Green Party emit by far the most CO2 when it comes to […]

Do you feel helpless when trying to assess the veracity of “climate doom is looming” claims we are constantly bombarded with? For ordinary citizens, it seems nearly impossible to tell right from wrong when it comes to assess such claims. Don’t give up trying to understand the relevant basics, there is a rather simple way […]

Evidence of abundant lakes and ponds and the remains of vascular plants, warmth-demanding beetles, sponges, spruce forests…in a newly-discovered organic-rich deposit 480 m above sea level in High Arctic (76.4°N) northwest Greenland indicates the local climate was similar to that of today’s southern Greenland (~60°N) and North America during the Early Pleistocene ice age. Scientists […]

Claims the Swedish Scandes are unprecedentedly warm and tree-covered today “appear as large and unfounded exaggerations,” as the “climate and arboreal responses” of the last few decades “are still inside the frames of natural historical variation.” – Kullman, 2022 and Kullman, 2022a Extensive birch forest fossils can be dated to the early- to mid-Holocene in […]

A “widespread greening trend” has been “significantly cooling the land surface” since the 1980s. Another new study documents a clearly-defined land surface greening trend over the last 40 years. The greening is linked to CO2 fertilization and climate change (warming). Greening, in turn, leads to land surface cooling, partially offsetting recent warming. Image Source: Li […]
