A prominent feature of all climate model projections is their prediction that temperatures should be rising in response to ever-increasing concentrations of greenhouse gases. However, for the past two decades global surface air temperatures have not warmed to the degree predicted by the models, which lack of warming has been a conundrum to the climate alarmist movement.

De tous temps les hommes se sont intéressés au climat et ont tenté de prévoir son évolution. Dès l’Antiquité il était connu que des caractéristiques géographiques comme la latitude mais aussi l’altitude ou le voisinage de vastes étendues d’eau avaient une grande influence sur le climat. Sur cette base les climatologues ont été amenés à distinguer différents types de climats tels que tropical, désertique, tempéré, polaire, etc. Ensuite, il est progressivement apparu que le climat est un système extrêmement complexe qui dépend de l’activité solaire ainsi que de la distance et de l’orientation de la Terre par rapport au Soleil, facteurs qui varient à des échelles de temps très différentes.

With wildfires engulfing over 620,000 acres of California, there’s been a concerted media campaign to single out man-made global warming as the primary force behind the deadly blazes.
But that’s not what the data suggests, according to University of Washington climate scientist Cliff Mass.
“So there is a lot of misinformation going around in the media, some environmental advocacy groups, and some politicians,” Mass wrote in the first of a series of blog posts analyzing the California wildfires.

Syracuse University professor uses ancient marine sediment as benchmark for present, future climate models
SYRACUSE, N.Y. – Researchers at Syracuse University are looking to the geologic past to make future projections about climate change.
Christopher K. Junium, assistant professor of Earth sciences in the College of Arts and Sciences (A&S), is the lead author of a study that uses the nitrogen isotopic composition of sediments to understand changes in marine conditions during the Paleocene-Eocene Thermal Maximum (PETM)–a brief period of rapid global warming approximately 56 million years ago.
Junium’s team–which includes Benjamin T. Uveges G’17, a Ph.D. candidate in A&S, and Alexander J. Dickson, a lecturer in geochemistry at Royal Holloway at the University of London–has published an article on the subject in Nature Communications (Springer Nature, 2018).
