I am an independent scientist, environmentalist and writer.
My primary university degree was in Chemistry, and my PhD in computational chemistry/polymer physics. However, in 2004, I shifted to environmentalism, and began working with my father, Dr. Michael Connolly, on developing sustainable methods of fish-farming, aquaponics and waste-water treatment. We also carried out research into developing low-cost heat exchanger systems and new energy efficient building materials and techniques.
In 2009, we began systematically investigating the challenging subject of climate change in detail. After five years of this research, we realised that we had gained a lot of important insights which would be of interest to the scientific community. We set up a website, OpenPeerReviewJournal.com, where we published all our results and findings as a series of eight scientific papers.
We also realised that our findings could be of interest to the general public, and so we also set up a separate website, Globalwarmingsolved.com, in which we summarised our findings in a less technical format. My mother, Dr. Imelda Connolly, also worked with us on it.
Since then, we have met and/or discussed our findings with hundreds of scientists around the world. We have sought and received useful feedback on our research, and this has led to several useful scientific collaborations. We have written up and published the results of several of these collaborations in peer-reviewed journals (see the “Peer-reviewed publications” section for more details).
In 2018, I began working full-time on my climate change and environmental research through a new international research group, the Center for Environmental Research and Earth Sciences (CERES-Science.com).
Currently, I am writing a book on “Bridging the political divide on climate change” (see the “Ongoing projects” section for more details). I am also continuing my scientific research through a number of collaborative projects with other researchers. We are writing and publishing our findings in peer-reviewed journals as time permits.
Ongoing projects
1. Book project: “Bridging the political divide on climate change”
I am writing a book on how and why climate change has become such a partisan politicised issue, and whether anything can be done to overcome these political divides. The working title of my book is, “Bridging the Political Divide on Climate Change”.
The theme of the book is trying to understand why the debate over whether recent climate change is mostly human-caused vs. mostly natural has become a left/right political issue. Are we doomed to become increasingly partisan on this nominally scientific problem – with each side becoming more convinced that the opposing side are irrational and “anti-science”? Click here for a pdf elaborating on the significance of this partisan divide.
2. Ongoing scientific research
- Global temperature datasets. Including temperature data homogenization; evaluating and correcting for non-climatic biases
- Using weather balloon data to study atmospheric behaviour
- Relationships between human-caused emissions and atmospheric concentrations of trace gases
- Sustainable aquaculture and water purification systems
- Why is climate change a partisan issue?
- Evaluating greenhouse gas emission scenarios
- Assessing environmental impacts of renewable energy systems

- OpenPeerReviewJournal.com – This is a website where my father, Dr. Michael Connolly, and I uploaded eight scientific papers describing the results of our research into climate change from 2009 until 2014. As the papers were quite long and technical, and covered many different fields of expertise, we decided to put all of this research online for open peer review.
- Globalwarmingsolved.com – This is a less technical blog summarising our climate change research in a more accessible format for the general public.

In 2014, my father (Dr. Michael Connolly) and I published 8 articles on a website we set up called Open Peer Review Journal. The website is a new approach to open peer review where anybody can register and provide review comments on a given article.
