Le catastrophisme climatique des années 60 à 80 à l’épreuve des faits

by Cédric Moro, 15 octobre 2018 in MythesMancies&Mathématiques

Les discours alarmistes sur le climat ne datent pas d’hier. Grâce à la numérisation des archives audio-visuelles et à leur mise en ligne sur internet, il est possible aujourd’hui de démentir les prévisions climato-catastrophistes assénées de manière très officielle dans la deuxième moitié du siècle dernier. Beaucoup des déformations de nos discours sur la réalité tendent à puiser leurs racines dans nos représentations mentales du monde. Nous verrons donc que ces représentations alarmistes naissent dans un contexte idéologique nouveau : mutation de l’eugénisme, collapsologisme et décroissance.

IPCC achieves net zero credibility

by Barry Brill, October 14, 2018 in WUWT

The recently released IPCC SR15 reports (at A1) that global warming is likely to reach 1.5°C between 2032 and 2050 and (at B) will probably bring species extinction, weather extremes and risks to food supply, health and economic growth. If we are to avoid this, net CO2 emissions will need to decline by about 45% from 2010 levels by 2030, reaching net zero by 2050 (C1), followed by extensive removals (C5). The required energy investment alone will be $2.4 trillion per year.

Is this possible?

As at 2015, which was not materially different from 2010, more than half the planet’s total CO2 emissions (36Gt) were sourced from just three countries:


Reliable? CRU, NASA, BEST, NOAA Land Temp Data Conflict By Up To 90% (0.8°C), Spawning ‘Large Uncertainty’

by K. Richard, October 8, 2018 in NoTricksZone

A new paper documents “remarkably different” land temperatures from one instrumental data set to another. In some regions there is as much as an 0.8°C conflict in recorded temperature anomalies for CRU, NASA, BEST, and NOAA. The relative temperature trend differences can reach 90% when comparing instrumental records. Consequently, the uncertainty in instrumental temperature trends — “0.097–0.305°C per decade for recent decades (i.e., 1981–2017)” —  is as large or larger than the alleged overall warming trend itself for this period.
