CLIMATE CHANGE WILL TAKE LONGER, SAY SCIENTISTS

by Dr David Whitehouse, September 19, 2017 in GWPF


The study is published in the journal Nature Geoscience by a team of scientists led by Richard Millar of the University of Oxford. It has recalculated the carbon budget for limiting the Earth’s warming to 1.5 degrees Celsius above temperatures seen in the late 19th century. It had been widely assumed that this stringent target would prove unachievable, but the new study would appear to give us much more time to act if we want to stay below it.

Irma : un record de rumeurs

by Cédric Moro, 18 septembre 2017 in Mythes,Mancies&Mathématiques


Que n’a-t-on pas entendu dans une partie de la presse et dans les déclarations à chaud de scientifiques et d’experts du climat sur l’uragan Irma. C’était du jamais vu, du jamais mesuré, d’une puissance inégalée, Europe 1 allant jusqu’à parler « du plus important de l’histoire climatologique ». Des eaux extraordinairement chaudes devaient expliquer son intensité effroyable (sous-entendu :  Irma, c’est la faute au réchauffement), ses vents destructeurs records, son diamètre exceptionnel, ses pluies diluviennes, son raz de marée démesuré, son intensification inouïe ou ses dégâts hors normes…

SEA LEVEL: Rise and Fall – Part 1

by Kip Hansen, September 13, 2017 in WUWT


I have written about sea level rise here:  here, here, here, here and here.  The previous essays are not prerequisites but are interesting specific examples.

There are two important points which readers must be aware of from the first mention of SLR:

  1. SLR is a real imminent threat to coastal cities and low-lying coastal and near-coastal densely-populated areas.

  2. SLR is not a threat to anything else — not now, not in a hundred years — probably not in a thousand years — maybe, not ever.

Carbon dioxide emission-intensity in climate projections: Comparing the observational record to socio-economic scenarios

by F. Pretis and M. Roser, June 2017, Energy, Elsevier


 

The wide range of socio-economic scenarios in climate projections results in high uncertainty about climate change.

We compare socio-economic scenario projections to observations over 1990–2010.

Global CO2 emission intensity increased despite all major scenarios projecting a decline.

Under-projection of emission intensity raises concerns about achieving emission targets.

 

Open letter to UN Secretary-General: Current scientific knowledge does not substantiate Ban Ki-Moon assertions on weather and climate, say 125-plus scientists

by Habibullo I. Abdussamatov  +125/et al., November 29, 2012, in Washington Post


On November 13, 2012, you said at Yale: “The science is clear; we should waste no more time on that debate.”

We the undersigned, qualified in climate-related matters, wish to state that current scientific knowledge does not substantiate your assertions.

Past Sea Levels Rose 4-6 Meters Per Century, Shorelines Retreated 40 Meters Per Year…Without CO2 Flux

by Kenneth Richard, September 7, 2017 in NoTricksZone


This modern rate  –  just 0.17-0.18 of a meter per century has remained relatively unchanged from the overall 20th century average, and there has been no statistically significant acceleration in the sea level rise rate (just 0.0042 mm/yr-²) since 1900.

Unanticipated Stability: Latest Polar Conditions Show No Signs Of Global Warming Melting

by P. Gosselin, August 16, 2017 in NoTricksZone


Weather and climate analyst Schneefan here writes of “early frost” in the Arctic and how Greenland snow and ice have grown after being hit by a “snow bomb”. This contradicts the expectations of global warming alarmists.

The polar summer this year appears to have ended prematurely. The mean temperature of the central Arctic above 80°N has remained under the long-term average over the entire summer and even dipped below the freezing point about a week earlier than normal (1958-2002 mean).

Why ‘Hide The Decline’? There Has Been No Net NH Warming Since The 1940s

by Kenneth Richard, August 31, 2017 in NoTricksZone


In the press release for a newly published and controversial  peer-reviewed scientific paper, Australian scientist Dr. Jennifer Marohasy unveiled one of climate science’s better-kept secrets.

She and her colleagues are well aware that the post-1940s Northern Hemisphere (NH)  proxy evidence from tree-rings, bore holes, pollen, etc., consistently fails to affirm sharply rising temperatures from the late 20th century onwards.
