This essay extends the previously published evaluation of CMIP5 climate models to the predictive and physical reliability of CMIP6 global average air temperature projections.
Precision research by physicists William Happer and William van Wijngaarden has determined that the present levels of atmospheric carbon dioxide and water vapor are almost completely saturated. In radiation physics the technical term “saturated” implies that adding more molecules will not cause more warming.
Knowing the future climate is very important, because we can take steps to adapt to climate change, saving lives and property. And the threat of unpleasant consequences can motivate society to take steps to reduce carbon emissions into the atmosphere and increase carbon storage in the ground.
While solar power is a leading form of renewable energy, new research suggests that changes to regional climates brought on by global warming could make areas currently considered ideal for solar power production less viable in the future.
According to a study whose authors include Ken Caldeira, China’s efforts to eliminate its infamous air pollution could cause an additional 0.1C NH warming, because less sunlight will be reflected by aerosols. However, despite suggesting China’s improved air quality is a “climate setback”, Caldeira acknowledged cleaner air is a net improvement.
Comparative study of the GEOMAR illustrates dependence on model resolution Climate models can only provide an approximation to the real world. Some models still suffer from relatively large biases in the sea surface temperatures of the tropical Atlantic. A new study by GEOMAR Helmholtz Centre for Ocean Research Kiel shows that in a model with…
Admitting some cloud error is as close as most climate modellers come to admitting their projections are not fit for purpose. Note the image is from Pat Frank’s paper about cloud error, not Paulo Ceppi and Ric Williams’ paper.
There is unequivocal proof Malaria does not need a warm climate – brief periods of warmth are enough. Malaria used to be a major cause of death in Northern Europe, during the depths of the Little Ice Age. Yet scientists still persist with pushing the myth that Malaria is somehow constrained by global climatic conditions.
This is an article with a simple proposition. Science tells us that rapidly rising Co2 in turn causes rising temperatures, which has become a very serious problem for humanity.
Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better.
