The Sahara Is Growing (Even Though It’s Wetter & Greener!)

by P. Homewood, April 1, 2018 in NotaLotofPeopleKnowThat

The green shoots of recovery are showing up on satellite images of regions including the Sahel, a semi-desert zone bordering the Sahara to the south that stretches some 2,400 miles (3,860 kilometers).

Images taken between 1982 and 2002 revealed extensive regreening throughout the Sahel, according to a new study in the journal Biogeosciences.

The study suggests huge increases in vegetation in areas including central Chad and western Sudan.

THIS WEEK: By Ken Haapala, President

California Litigation, Monckton: Last week’s TWTW discussed on the public nuisance lawsuits by San Francisco and Oakland against oil companies claiming carbon dioxide (CO2)-caused global warming / climate change will cause harm in the future. It focused on the filing amicus curiae (friend of the court) brief by three distinguished Professors of Physics – William Happer, Steven Koonin and Richard Lindzen (Three Profs). The brief accepted the data and evidence used by the UN Intergovernmental Panel on Climate Change (IPCC) in its Fifth Assessment Report (AR5) and the Climate Science Special Report (CSSR) by the US Global Change Research Program (USGCRP). However, the Three Profs demonstrate the conclusions in the reports are not established, and, at best, premature. They assert:

“Our overview of climate science is framed through four statements


Uh oh– analysis of GHCN climate stations shows there is no statistically significant warming – or cooling

This is my eighth post in this series where I am examining long term temperature records for the period 1900 to 2011 contained in the Global Historical Climatology Network daily temperature records. I would encourage anyone to start at the first post and go forward. However, this post will serve as a standalone document. In this post I have taken my experience in exploring the history of Australia and applied it forward to cover North America and Europe.

The way to view this study is literally a statistic-based survey of the data. Meaning I have created a statistic to quantify, rank, and categorize the data. My statistic is very straight forward; it is simply the net change in temperature between the first and last 10 years of 1900 through 2011 for each station.
