After 8 years the IPCC finally published a new Assessment Report, called AR6. The media went wild: climate change is going faster than ever; extremes are increasing; it has become close to impossible to stay under the 1.5 Celsius target and sea level rise is irreversible. And on and on and on... CLINTEL [...]
Figure: AR6 hockey stick "Climate change is accelerating". With these words, the 8 o'clock national news started last week. The reason: the new, sixth IPCC report. Various media published similar statements. Leftwing newspaper De Volkskrant: "UN panel IPCC: climate change is accelerating, man is 'unmistakably' the cause". Only De Telegraaf dared to let some [...]
by Ross McKitrick – repost from Climate Etc. One day after the IPCC released the AR6 I published a paper in Climate Dynamics showing that their “Optimal Fingerprinting” methodology on which they have long relied for attributing climate change to greenhouse gases is seriously flawed and its results are unreliable and largely meaningless. Some of the errors would [...]
The PETM or Paleocene-Eocene Thermal Maximum was a warm period that began between 56.3 and 55.9 Ma (million years ago). The IPCC AR6 report (actually a draft, not a final edited report), released to the public on August 9, 2021, suggests that this warm period is similar to what is happening today and they [...]
by Ross McKitrick - repost from Climate Etc. Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better. The papers are Mitchell et al. (2020) “The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal [...]
By Steve McIntyre - repost of Climate Audit About 20% of the PAGES 2019 proxies are 50 Asian tree ring chronologies, all of which were originally published as chronologies in PAGES (2013). At the time, none of these series (and certainly not in these digital versions, had ever been published in technical literature, [...]
By Steve McIntyre Original post here Although climate scientists keep telling that defects in their “hockey stick” proxy reconstructions don’t matter – that it doesn’t matter whether they use data upside down, that it doesn’t matter if they cherry pick individual series depending on whether they go up in the 20th century, that it [...]
Guus Berkhout Científicos del clima de los círculos del IPCC han admitido que la nueva generación de sus modelos de simulación del clima -denominados modelos CMIP6-, está "sobrecalentada", es decir, predice temperaturas superiores, y, por tanto, sus resultados son demasiado alarmantes. Esta concesión revolucionaria ha sido realizada en vísperas de la muy [...]
Paris le 10 août 2021 Déclaration de CLINTEL (*) sur la publication le 9 août 2021 du résumé à l’intention des décideurs (SPM) du Groupe de travail I (WG1) du sixième rapport d’évaluation du GIEC (AR6). (*) CLINTEL (Climate Intelligence) est une fondation indépendante européenne fondée en 2019 par le professeur émérite de géophysique néerlandais [...]
Το CLINTEL (Climate Intelligence) πραγματοποίησε προκαταρκτική επισκόπηση της περίληψης του Intergovernmental Panel on Climate Change (IPCC) του ΟΗΕ για τους υπεύθυνους χάραξης πολιτικής (SPM) της έκθεσης AR6 WGI (για τη Φυσική Επιστήμη) που εκδόθηκε (πρόσφατα). Φαίνεται ότι η έκθεση SPM είναι, όπως και προηγούμενες εκθέσεις, επιρρεπής σε υπερβολικές εκτιμήσεις δεδομένων και έτσι παρέχει [...]
