Does low atmospheric carbon dioxide cause drought and extreme weather?

“From 1900 to 1970, the Northeast US was in drought most of the time, and was plagued with large forest fires. But since 1970, the Northeast has been wet and has had very little drought.” click here

Here is a real climate crisis…

“Unlike the completely imaginary climate crisis of 2019, there was a very real climate crisis on this date in 1930.” click here

“Greening” deserts creates positive climate change

“Desertification is supposedly one result of catastrophic global warming – but reversing desertification through intensive agriculture is not high on the list of the “solutions” proposed by politicians and pundits in Washington and Geneva. Creating new markets, not destroying existing ones, has been the modus operandi in both Chinese and Israeli desert reclamation efforts.” click here

Dry summers come and go

“We aren’t the first scientists to confirm this trend,” says Dr. Tobias Scharnweber, one of the authors of the article. “However, what is new in our reconstruction is that we were able to calculate these growth rates using our own data method that we had developed especially for this project. This enabled us to show that average summer rainfall amounts were much lower at the time of the Mediaeval Climate Optimum, i.e. approximately 1000 years ago, than previously presumed. Maybe ‘one-in-a-century’ summers, like the one we had in 2018, were not that rare back then.” click here

Removing the no-analogue bias in modern accelerated tree growth leads to stronger medieval drought. Scientific Reports, volume 9, Article number: 2509 (2019).

In many parts of the world, especially in the temperate regions of Europe and North-America, accelerated tree growth rates have been observed over the last decades. This widespread phenomenon is presumably caused by a combination of factors like atmospheric fertilization or changes in forest structure and/or management. If not properly acknowledged in the calibration of tree-ring based climate reconstructions, considerable bias concerning amplitudes and trends of reconstructed climatic parameters might emerge or low frequency information is lost. Here we present a simple but effective, data-driven approach to remove the recent non-climatic growth increase in tree-ring data. Accounting for the no-analogue calibration problem, a new hydroclimatic reconstruction for northern-central Europe revealed considerably drier conditions during the medieval climate anomaly (MCA) compared with standard reconstruction methods and other existing reconstructions. This demonstrates the necessity to account for fertilization effects in modern tree-ring data from affected regions before calibrating reconstruction models, to avoid biased results.

California’s “permanent drought” has been washed away

“A few years ago, some genius politicians, spurred on by some equally genius “climate scientists” told the citizens of California that we were now in a “permanent drought” situation. Of course, the NYT bought this drivel, and made it a headline.” click here

Mis-information campaign about California wildfires

“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.”
