At the University of Colorado, Roger founded and directed both the Center for Science and Technology Policy Research and the Sports Governance Center.

If We Imagine Really Bad Stuff, It Might Affect Crop Yields.

…use large ensembles to generate plausible unprecedented events, which can inform our assessment of the risk to crops

The IPCC Reports have become “bumper sticker” climate science

Emissions and CO2 Concentration: An Evidence Based Approach

Therefore, if we keep living our lives with the current CO2 emissions – and a 3%/decade efficiency improvement, then the Paris climate goals are fulfilled.

Claim: Skiing over Christmas holidays no longer guaranteed – even with snow guns

Current climate models predict that there will be more precipitation in winter in the coming decades, but that it will fall as rain instead of snow.

The Climate ‘Crisis’ Isn’t What it Used to Be

Pielke Jr. on IPCC AR6 WG2 Release

The first observation is that the report is more heavily weighted to implausible scenarios than any previous IPCC assessment report

Dr Roger Pielke, Jr -What does IPCC AR6 say on Scenarios and Extreme Weather?

. It is very appealing, even seductive, for activists and the media to latch on to extreme events (as inaccurately summarized in the SPM), but at some point we have…

IPCC Model Scenarios Compared To Actual Measured Temperatures

In an effort to hold the IPCC accountable, I have compared actual measured temperatures with two of their scenarios from the AR4 report in 2007. The B1 and A2 scenarios.…

Why the IPCC focuses on the scenarios that it does

It is more than a little silly to have a breathlessly-awaited, embargoed report presenting analysis of out-of-date scenarios, but here we are!

The ECB’s climate models are built on obsolete scenarios

There is an urgent need to not just update climate scenarios, but to implement a process whereby they can be kept instantaneously current … we can do this, we know…

Crisis looms in alarmist climate science

Climate science is dominated by alarmists addicted to the idea that increasing carbon dioxide will cause dangerous global warming. How much warming is thus the central scientific question.
