I have become wary of people who say “the science is settled” or “all scientists agree”. There are many who do not agree we are in a climate emergency.
Here is a list of links to blogs and websites. More details down the page…
- (2019) Climate Intelligence
- (2010) Climate Etc.
- (1997) Global Warming Petition Project
Articles
A few selected articles that collate published evidence.
- Climate Change – the impacts and the need to act. (Judith Curry giving evidence to US Congress in 2019).
- Environmental Effects of Increased CO2 (Petition Project).
Interviews
- Judith Curry – this interview is a good primer to many of the uncertainty issues around climate change. Judy has spent 40 years studying weather and climate. The interview is dense with info. I have been making a page of notes here.
(2019) Climate Intelligence (clintel.org)
An independent foundation informing people about climate change and climate policies. Clintel was founded in 2019 by emeritus professor of geophysics Guus Berkhout and science journalist Marcel Crok.
Hosts the World Climate Declaration. The pdf (January 2025) lists 1,975 people from many countries. From many disciplines. Can they really be paid by the fossil fuel industry to obfuscate the truth?
Their declaration:
- Natural as well as anthropogenic factors cause warming
- Warming is far slower than predicted
- Climate policy relies on inadequate models
- CO2 is plant food, the basis of all life on Earth
- Global warming has not increased natural disasters
- Climate policy must respect scientific and economic realities
(1997)The Petition Project
This is a response by scientists concerned about the Kyoto agreement (December 1997). World leaders gathered in Kyoto to consider a world treaty to restrict human production of greenhouse gases (especially CO2).
These scientists could see no basis in fact for this treaty.
They put together a review paper and started collecting signatures for the petition below.
We urge the United States government to reject the global warming agreement that was written in Kyoto, Japan in December, 1997, and any other similar proposals. The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind.
There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.
They have 30,000+ signatories (9,000 are PhD). It’s 25 years old now. The website is like a trip down memory lane. And it’s slightly sexist – “When a scientist desires to refine his understanding of a specific scientific subject, he often begins by reading one or more review articles about that topic.”
They have a 12-page review article with 132 references, summarising research into atmospheric carbon. Published in 2007 (Journal of American Physicians and Surgeons (2007) 12, 79-90). And on their website here. Lots of numbers, data, facts.
Steven E Koonin
Authored a book “Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters.”
Theoretical physicist Steven Koonin, University Professor at New York University and a senior fellow at the Hoover Institution, explains from the research literature and government assessment reports that the science of climate emergency is not settled.
He highlights surprises in the official science that belie the notion that we’ve already broken the climate and face certain doom unless we take prompt and drastic action and suggests pragmatic conclusions about national and international climate policies.
Judith Curry
The IPCC has oversimplified the problem and the solution. Slow creep of global warming, confounded by natural variation. Not clear how dangerous this is. And deep uncertainty about how the climate is going to change in the future. A different way of framing the problem so we can make more robust decisions.
November 2009. Climategate. I was interacting with all the sceptic blogs. Trying to calm the waters – wrote series of essays on Climate Audit. Spouting common sense – transparent, data available, honest about what we don’t know, respectful of people who don’t agree. Got a lot of flack for this! Became an enemy. Labelled as a denier (tossed into the camp of cranks and oil companies). Google profile becomes serial climate denier! 2017 resigned faculty position to work in the private sector. Trying to preserve the integrity of scientific research. The science debate and the policy debate.
Ross McKitrick
(2022) Ross McKitrick is a Professor of Economics at the University of Guelph where he specializes in environment, energy and climate policy. He has published widely on the economics of pollution, climate change and public policy. His book Economic Analysis of Environmental Policy was published by the University of Toronto Press in 2010. His background in applied statistics has also led him to collaborative work across a wide range of topics in the physical sciences including paleoclimate reconstruction, malaria transmission, surface temperature measurement and climate model evaluation. Professor McKitrick has made many invited academic presentations around the world, and has testified before the US Congress and committees of the Canadian House of Commons and Senate.
