Rebelling against the Extinction Rebellion

by Larry Kummer

Compare the alarmists’ claims with what scientists said in the IPCC’s Fifth Assessment Report (AR5). Too bad that journalists don’t.

Rise in CO2 has greened planet Earth

by Judith Curry

We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend. – Zhu et al.
