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,
By Bjorn Lomborg It’s human nature to assign blame for catastrophic events. In medieval times, witches were blamed for weather woes. Trials and burnings increased when weather got worse. In hurricane season today, many find a scapegoat in global warming. Pundits tell us “ignoring the science of climate change will hurt us” (Kristina Ball at
Study links natural climate oscillations in north Atlantic to Greenland ice sheet melt WOODS HOLE OCEANOGRAPHIC INSTITUTION Scientists have known for years that warming global climate is melting the Greenland Ice Sheet, the second largest ice sheet in the world. A new study from the Woods Hole Oceanographic Institution (WHOI), however, shows that the rate
By Ross McKitrick I sat down to write a description of my new paper with John Christy, but when I looked up a reference via Google Scholar something odd cropped up that requires a brief digression. Google Scholar insists on providing a list of “recommended” articles whenever I sign on to it. Most turn out

Sciences in Cold and Arid Regions 9: 0046-0053, DOI: 103724/SP.J.1226.2017.00046. In this posting we review the work of two Chinese scientists, Liu and Chen (2017), who performed a significant and thorough investigation of
By Roy W. Spencer Hurricane Florence is not the result of global warming. It’s likely due to natural weather patterns, not climate change as some have already said. Even before Hurricane Florence made landfall somewhere near the border of North and South Carolina, predicted damage from potentially catastrophic flooding from the storm was already being

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;
By David Kreutzer In today’s hyper-politicized world of climate science, hardly a thunderstorm passes without somebody invoking the “scientists say” trope to blame it on carbon emissions. The logic seems to be: If it’s bad, it was caused by carbon emissions, and we are only going to see more and worse. More and worse floods,
By Roy Spencer As part of the 2nd edition of my Kindle e-book Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming (which should go live tonight), I include the following graph, based upon data in a January 2018 U.S. Government report. In the top panel we see that the average monetary damages of
By Kenneth Richard Even though CO2 concentrations hovered well below 300 ppm throughout most of the Holocene, newly published paleoclimate reconstructions affirm that today’s surface temperatures are only slightly warmer (if at all) than the coldest periods of the last 10,000 years. This contradicts the perspective that temperatures rise in concert with CO2 concentrations. Bottom Graph
The CO2 Coalition was established in 2015 as a 501(c)(3) for the purpose of educating thought leaders, policy makers, and the public about the important contribution made by carbon dioxide to our lives and the economy.
Carbon dioxide is the primary source of carbon life; in other words, without CO2, there would be no life on earth https://t.co/JL2cE5KydB
