The land surface is cooling

“Finally, I’ve never seen a climate model from the turn of the century that predicted that for the first 18 years of the 21st Century the land would be cooling … and despite that, we’re supposed to believe that those same climate models can tell us what the temperatures will be doing in the year 2100 …” click here

Changing the data causes global warming, not carbon dioxide

“Unfortunately, the current NASA graph doesn’t even agree with their earlier graphs.  Eighteen years ago, NASA showed 0.5C warming prior to the year 2000.  Now they show twice as much warming prior to 2000.” click here

The French lead the way to end the global warming crusade?

“The French love a good riot, but the political backlash to the French government’s plans to increase carbon taxes on fuel could be a harbinger of what’s to come in countries committed to the global warming crusade.” click here

US temperature extremes have become more moderate

“Chapter 6 – Temperature Changes in the United States of the U.S. Global Change Research Program’s recently published Climate Science Special Report (2017) clearly shows and discusses, under the heading of “6.1.2 Temperature Extremes”, how temperature extremes for the contiguous United States have become more moderate over the last 118 years, with the coldest daily temperatures warming and the warmest daily temperatures cooling. In other words, temperature-extreme-related climate in the United States has improved.” click here

Is the global temperature record credible?

Systematic errors in Resplandy et al 2018 paper highlights the problem of inadequate peer-review

“However Lewis, who has authored several peer-reviewed papers on the question of climate sensitivity and has worked with some of the world’s leading climate scientists, has found that the warming trend in the Resplandy paper differs from that calculated from the underlying data included with the paper.” click here and here

Cold temperatures pose greater health risk than warm, India

Fu SH, Gasparrini A, Rodriguez PS, Jha P (2018) Mortality attributable to hot and cold ambient temperatures in India: a nationally representative case-crossover study. PLoS Med 15(7): e1002619. https://doi.org/10.1371/journal.pmed.1002619

Author summary

Why was this study done?

Very few studies from low- and middle- income countries (LMICs) have examined daily hot and cold temperature effects on cause-specific mortality.

  • This is, to our knowledge, the first study to estimate cause-specific deaths attributable to daily hot and cold temperatures in India using nationally representative mortality data spanning a 13-year period.

What did the researchers do and find?

  • We used a case-crossover method and distributed-lag nonlinear models (DLNM) to assess the nonlinear and delayed associations between temperature and mortality risk.
  • We found substantial numbers of cause-specific deaths attributable to moderately cold temperature, which were approximately 12 times greater than deaths due to extremely cold temperature and 42 times greater than deaths due to extremely hot temperature.
  • Our results also showed that moderately cold temperature was associated with the highest number of deaths from stroke at ages 30–69 years and from respiratory diseases at ages 70 years and above.

What do these findings mean?

  • Public health authorities should consider the detrimental effects of moderately cold and extremely hot temperatures in their mitigation strategies, particularly as the absolute population totals in India exposed to moderately cold and extremely hot temperatures have risen by about 270 and 10 million, respectively, in the last three decades.
  • To provide reliable national estimates of temperature–mortality associations in other LMICs, large-scale and nationally representative mortality data are needed.
