Thermosphere climate indexes: Percentile ranges and adjectival descriptors

By Martin G.Mlynczak, Linda A.Hunt, James M.Russell and B. Thomas Marshall Highlights This paper describes a new solar terrestrial Index with quantitative terrestrial context. Adjectival descriptors (Hot, Warm, Neutral, Cool, Cold) are assigned to the new Index. The thermosphere in solar cycle 24 had the coldest maximum of the past seven solar cycles. The present

The most amazing greening on Earth

By Patrick J. Michaels We’ve long been fond of showing the satellite evidence for planetary greening caused by increasing carbon dioxide, particularly the work of Zhu et al.(2016): Figure 1: Trends in Leaf Area Index around the planet. Note the units are in hundredths (10-2) of meters per square meter. An increase of 25 (Purple,

Natural Variability Dominates Recent Climate Change

Paper Reviewed Babich, V.V., Darin, A.V., Smolyaninova, L.G. and Kalugin, I.A. 2017. Natural periodic processes and climate variability in the Northern Hemisphere. Doklady Earth Sciences 477: 1470-1472. How natural is current climate change? The above question has fostered considerable discussion in the global warming debate in recent years. Responses range across a spectrum of viewpoints;
