Ouch! ‘Senate global warming hearing backfires on Democrats’ — Boxer’s Own Experts Contradict Obama! — ‘Skeptics & Roger Pielke Jr. totally dismantled warmism (scientifically, economically, rhetorically) — Climate Depot Round Up

limate Depot Round Up of July 18, 2013 Senate Environment & Public Works Committee Global Warmnig Hearing:
‘Sen. Boxer’s Own Experts Contradict Obama on Climate Change’   – During yesterday’s Environment and Public Works hearings, Sen. David Vitter asked a panel of experts, including experts selected by Boxer, “Can any witnesses say they agree with Obama’s statement that warming has accelerated during the past 10 years?” For several seconds, nobody said a word. Sitting just a few rows behind the expert witnesses, I thought I might have heard a few crickets chirping, but I couldn’t tell for sure. We’ll give Obama the benefit of the doubt and count the crickets in the “maybe” camp. After several seconds of deafening silence, global warming activist Heidi Cullen, who formerly served as a meteorologist for the Weather Channel, attempted to change the subject. Cullen said our focus should be on longer time periods rather than the 10-year period mentioned by Obama. When pressed, however, she contradicted Obama’s central assertion and said warming has slowed, not accelerated. Several minutes later, Sen. Jeff Sessions returned to the topic and sought additional clarity. Sessions recited Obama’s quote claiming accelerating global warming during the past 10 years and asked, “Do any of you support that quote?” Again, a prolonged and deafening silence ensued. Neither Cullen nor any of the other experts on the panel spoke a word, not even in an attempt to change the subject.
Climatologist Dr. Judith Curry on Warmist Heidi Cullen’s testimony: ‘She does include some dubious and misleading statements’ – Curry on warmist  Jennifer  Francis: ‘She makes several statements about the science that seem to me to be misleading’
Warmist Heidi Cullen’s claim at Senate climate hearing of ‘73% increase in heavy downpours’ is not supported by data – What the data says: ‘Floods have not increased in the US in frequency or intensity since at least 1950.’
Full Senate Testimony of Climatologist Dr. Roy Spencer formerly of NASA: ‘Weather and climate vary naturally, and by amounts that are not 2 currently being exceeded; (2) global warming theory is just that – based upon theory; & (3) there is no unique fingerprint of human caused global warming’ – Spencer is Principal Research Scientist IV University of Alabama, Huntsville: ‘The belief that global warming and associated climate change involve more severe weather cannot be supported observationally…There is little or no observational evidence that severe weather of any type has worsened over the last 30, 50, or 100 years, irrespective of whether any such changes could be blamed on human activities, anyway. Long-term measurements of droughts, floods, strong tornadoes, hurricanes, severe thunderstorms etc. all show no obvious trends, but do show large variability from one decade to the next, or even one year to the next.’
PROF. ROGER PIELKE JR: TESTIMONY ON THE CURRENT STATE OF WEATHER EXTREMES: ‘It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally’ – Link to full testimony of Roger Pielke Jr. to Congress: ‘It is further incorrect to associate the increasing costs of disasters with the emission of greenhouse gases’  Globally, weather-related losses ($) have not increased since 1990 as a proportion of GDP (they have actually decreased by about 25%) and insured catastrophe losses have not increased as a proportion of GDP since 1960.
• Hurricanes have not increased in the US in frequency, intensity or normalized damage since at least 1900. The same holds for tropical cyclones globally since at least 1970 (when data allows for a global perspective).

• Floods have not increased in the US in frequency or intensity since at least 1950. Flood losses as a percentage of US GDP have dropped by about 75% since 1940.
• Tornadoes have not increased in frequency, intensity or normalized damage since 1950, and there is some evidence to suggest that they have actually declined.
• Drought has “for the most part, become shorter, less frequent, and cover a smaller portion of the U. S. over the last century.” Globally, “there has been little change in drought over the past 60 years.”

• The absolute costs of disasters will increase significantly in coming years due to greater wealth and populations in locations exposed to extremes. Consequent, disasters will continue to be an important focus of policy, irrespective of the exact future course of climate change.’
Scientist tells senators: Global warming not causing extreme weather – Prof. Roger Pielke Jr. : ‘It is misleading and just plain incorrect to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the U.S. or globally’
Read Full 21-Page GOP Senate Climate Report: ‘Critical Thinking on Climate Change’: – ‘Questions to Consider Before Taking Regulatory Action and Implementing Economic Policies’ Wildfires have not increased: ‘Historical analysis of wildfires around the world shows that since 1950 their numbers have decreased globally by 15%. Estimates published in the Proceedings of the National Academy of Sciences show that even with global warming proceeding uninterrupted, the level of wildfires will continue to decline until around midcentury and won’t resume on the level of 1950—the worst for fire—before the end of the century.’
Flashback May 2013: Submitted Written Testimony of Climate Depot’s Marc Morano at Congressional Hearing on Climate Change: ‘The Origins and Response to Climate Change’ — Morano to the U.S. Congress: ‘The scientific reality is that on virtually every claim — from A-Z — the claims of the promoters of man-made climate fears are failing, and in many instances the claims are moving in the opposite direction. The global warming movement is suffering the scientific death of a thousand cuts.’
