Everyone is focused on the US withdrawal from Paris and the tariff threat, but several other Executive Orders yesterday will have even more radical impacts and will require Canada to rethink all our energy and climate policies in response. /... whitehouse.gov/presidential-a…

To all those for whom one bad year = a trend, and "climate change" explains everything, here two UK experts discuss the real challenges of explaining patterns in global wildfires.

THREAD: Two new papers from independent teams show convincingly that climate models exaggerate atmospheric warming and the bias has gotten worse over time. When forced with observed GHG levels all the new gen models ("CMIP6") overshoot the observed post-1979 warming. refs: Mitchell et al. “The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability” Env Research Letters iopscience.iop.org/article/10.108…, and

I have a column today on the IPCC's RCP8.5 GHG emissions scenario. business.financialpost.com/opinion/ross-m…
RCP8.5, like A1FI and others before it, is part of a history of exaggerated top-end scenarios that create misleading pictures about the business-as-usual future. h/t @RogerPielkeJr and his coauthors who have been doing a lot to push back against misuse of RCP8.5 in the academic community.

Been reading Ch 4 of the Env Can Climate Change report. It's not what you might expect from the alarmist media coverage, instead it's measured, rooted in data and interesting.
