Nuclear energy a key climate mitigation technology?

“Today’s release of a Union of Concerned Scientists report calling for policies to support continued operation of nuclear power plants marks a watershed. UCS is the first major environmental NGO to recognize that nuclear energy presently, and for the foreseeable future, is a key climate mitigation technology. It is also the first to publicly and explicitly call for policies to support nuclear energy.” click here

US national climate – Not so bad afterall.

“The BBC inevitably made a lot of propaganda out of the latest US National Climate Assessment report, which I have already shot holes in. But below is the report the climate scientists did not want to publish: click here

Is the USGCRP Climate Report fake news?

“Obama-era deep-state bureaucrats have issued a dubious climate report that warns of imminent devastation from global warming. The report presents discredited assertions from environmental activist groups as “evidence” to support its findings, as well as predictions of temperature change and extreme weather events that have already been contradicted by real-world data.” click here

Taking a closer look at NCA4; Is RCP8.5 bad science fiction?

Volume I of NCA4 (Climate Science Special Report) features this nifty image of projected global temperatures (°F) for several Representative Concentration Pathway (RCP) scenarios.  RCP2.6 is a drastic mitigation scenario, RCP4.5 is a strong mitigation scenario, RCP8.5 is bad science fiction and often described as “business as usual.”  All the really bad stuff happens in an RCP8.5 world.” click here

Children are seriously mislead, deceived in pursuing climate lawsuit

“Chief Justice John Roberts ordered a stay recently of a “landmark” trial in the federal lawsuit against the United States and various executive agencies, filed on behalf of 21 children “and future generations.”  Juliana v. United States alleges violations of the children’s fundamental right to “a climate system capable of sustaining human life.”  Acting as the guardian for the minor plaintiffs is James Hansen, the climate change equivalent of Patient Zero in the pandemic of terror over global warming.” click 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.

 

Majority of European Alpine glacier melt occurred prior to 1875

Sigl, M., Abram, N. J., Gabrieli, J., Jenk, T. M., Osmont, D., and Schwikowski, M.: 19th century glacier retreat in the Alps preceded the emergence of industrial black carbon deposition on high-alpine glaciers, The Cryosphere, 12, 3311-3331, https://doi.org/10.5194/tc-12-3311-2018, 2018.

“Starting around AD1860, many glaciers in the European Alps began to retreat from their maximum mid-19th century terminus positions, thereby visualizing the end of the Little Ice Age in Europe. Radiative forcing by increasing deposition of industrial black carbon to snow has been suggested as the main driver of the abrupt glacier retreats in the Alps. The basis for this hypothesis was model simulations using elemental carbon concentrations at low temporal resolution from two ice cores in the Alps.”

“Our study reveals that in AD1875, the time when rBC ice-core concentrations started to significantly increase, the majority of Alpine glaciers had already experienced more than 80% of their total 19th century length reduction, casting doubt on a leading role for soot in terminating of the Little Ice Age.”
