Responding to the CO2 Coalition's "Facts #29, #30 and #31" on US and Global Droughts

 CO2 Coalition's "Fact #29," "Fact #30" and "Fact #31" are essentially the same strawman attacks having to do with claims about droughts that nobody is actually saying. They basically observe here that there has been no change in droughts in the US, and droughts are declining globally. Here are the graphs they use to support this point.

And yet who said otherwise? It's well-documented that warmer air holds more water, with water vapor increasing by ~7% for every 1 C warming. So on average, we should expect to see decreases in droughts as a global average. CO2 Coalition is attacking as strawman here.

Climate scientists also observe that in more arid areas with less water availability, warming increases vapor pressure deficit (VPD) which should drive local and regional increases in the frequency and intensity of droughts (I cover more about this here). This is observed in the American Southwest and in other areas around the world. In wetter areas with more water availability, warming should correlate with increased rainfall and risk of flooding.

The Marketing of Alt-Data at Temperature.Global

Image
Temperature.Global (12-month running average, sort of) A few years ago, I started seeing people post links to a new dataset for global temperatures at a website called temperature.global. There are at least four unique features of this dataset. First, the website claims to update global temperature in near real time. Second, every year in the dataset averages below "normal." Third, there is absolutely no transparency regarding their methodology (those who administer it are anonymous, most of the data is hidden, and much of their methodology is unclear). And fourth, what is disclosed about their methodology reveals that what they are calculating is not the Earth's surface temperature. Description of Temperature.Global If you go to the temperature.global website, it becomes almost immediately apparent that this website has little concern for transparency. The website is hosted by Parler (the alternative social network), which if nothing else is pretty odd. There are no name

Roy Spencer on Models and Observations

Image
A few days ago, Dr. Roy Spencer wrote a piece for the Heritage Foundation called, " Global Warming: Observations vs. Climate Models " ( PDF ) essentially arguing that models show too much warming compared to observations, and if we stick to observations, "global warming offers no justification for carbon-based regulation." He claims to frame his argument in terms of answering three questions: Is recent warming of the climate system materially attributable to anthropogenic greenhouse gas emissions, as is usually claimed? Is the rate of observed warming close to what computer climate models—used to guide public policy—show? Has the observed rate of warming been sufficient to justify alarm and extensive regulation of CO2 emissions? We should keep in mind that this is a political document intended to support the political aims of the Heritage Foundation, and Spencer has carefully selected what he says and doesn't say to fit the political agenda of the Heritage Found

Patrick Frank Publishes on Errors Again

Image
Recently I came across yet another paper by Patrick Frank[1] attempting to claim that climate scientists have been underestimating uncertainties in climate-related data. In this paper, he takes aim at GMST data, and he argues that  LiG resolution limits, non-linearity, and sensor field calibrations yield GSATA mean ±2σ RMS uncertainties of, 1900–1945, ±1.7 °C; 1946–1980, ±2.1 °C; 1981–2004, ±2.0 °C; and 2005–2010, ±1.6 °C. Finally, the 20th century (1900–1999) GSATA, 0.74 ± 1.94 °C, does not convey any information about rate or magnitude of temperature change. The resulting GMST graph from his calculations is below. Essentially, he's saying that errors associated with liquid in glass thermometers are so large that we can have no confidence in the global warming trend in the major GMST datasets. Of course, the organizations producing these GMST datasets all evaluate the uncertainties associated with their anomaly values, and their estimates are invariably much smaller - about ±0.05°
