Open letter: A recent Climate Feedback “fact-check” article makes multiple false and misleading claims about a new study and newspaper coverage of it

Dear Drs. Vincent and Forrester, We are writing this open letter to you because it has recently come to our attention that your Climate Feedback website has published an article making multiple false or misleading claims about an Epoch Times newspaper article (by Alex Newman) that reported on a new peer-reviewed paper we co-authored. Your […]

How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate

Press release for our recent, “How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate” paper:

A diverse expert panel of global scientists finds blaming climate change mostly on greenhouse gas emissions was premature. Their findings contradict the UN IPCC’s conclusion, which the study shows, is grounded in narrow and incomplete data about the Sun’s total solar irradiance.

Current climate models get snow cover trends wrong for all four seasons

Imelda and Michael in downtown Boston (Massachusetts, USA) during a visit we made in February 2015 to northeast USA to discuss our research with other scientists. According to current climate models the heavy snowstorms that occurred at the time (and which took several months to fully melt) should not have been occurring in 2015. In this post, we summarise the main findings of our 2019 peer-reviewed paper, “Northern hemisphere snow-cover trends (1967-2018): A comparison between climate models and observations” that was published in the scientific journal, Geosciences. We show that the current climate models are completely unable to explain actual trends in snow cover for all four seasons.

How much global warming should we expect under “business-as-usual” policies?

In this post, we summarise the key findings of our 2020 paper “How much human-caused global warming should we expect with business-as-usual (BAU) climate policies? A semi-empirical assessment” published in the scientific peer-reviewed journal, Energies.

Evaluating the human-caused and natural contributions to recent global warming

In this post, we briefly summarise some of the main findings of our 2015 paper with Dr. Willie Soon, “Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th century”, that was published in the journal, Earth-Science Reviews. This summary is adapted from a similar post from 2019 on the CERES-science website.

What do we know about Arctic sea ice trends?

This essay was originally written as an invited guest post for Dr. Judith Curry’s “Climate Etc.” blog. A slightly abridged version was published there on 16th August 2017.

In this essay we summarise the findings of our 2017 “Re-calibration of Arctic sea ice extent datasets using Arctic surface air temperature records” paper.
