A view of potential future impact of climate change
Among many doom-and-gloom forecasts about the sustainability of the planet; and the risk of an ‘existential crisis’ due to rising temperatures, one scientist has made a simple statement: It’s not as bad as it once looked David Wallace Wells is … Continue reading

Plausible impact of CO2 increase on global temperature
Lewis and Curry (2018) investigated the plausible overall temperature increase that could be attributable to Anthropogenic Global Warming (AGW), with a specific focus on radiative forcing and ocean heat uptake. The authors summarise their findings as follows: Using an 1869–82 … Continue reading

Climate models predict too much warming
Dr John Christy from the University of Alabama at Huntsville presented a paper to the UK Parliament. The paper outlines reasons that the computer simulations that are used to predict global warming are failing on a key measure of the … Continue reading

Climate models underestimate cooling effect of daily cloud cycle
Cloud formation is part of the hydrological cycle. The climate models that scientists use to project future conditions appear to underestimate the cooling effect that clouds have on a daily — and even hourly — basis, particularly over land. A study … Continue reading

U.N. Predicts Disaster if Global Warming Not Checked
There have been many predictions that there is a disaster looming if nothing is done to address the impact of humans on the climate. This prediction is a case in point. Unfortunately it was given in 1989. It is worth … Continue reading

Great Lakes – a case study of failed predictions
In 2012, National Geograhic published an article outlining the impact of climate change on the Great Lakes in North America. The article provides details of how the lakes were at almost-record lows, and that the temperatures were warming. The winter … Continue reading

Another forecast of doom
Time and again we are exposed to another article that tells us how long we, as the human race, have before there will be a cataclysmic disaster. Another such paper was prepared in Australia this week, and reported in global … Continue reading
