Guide to the Science of Climate Change in the Twenty-First Century by David H. Manz, Ph.D., P. Eng., AOE, FCAE, 2021.It is my wish that the Guide provides an introduction to the science of global warming and climate change that can be understood by anyone with an interest. It was inspired by my experiences as an instructor at the University of Calgary, Faculty of Continuing Education where I taught the subject since 2007, the same year the United Nations Intergovernmental Panel on Climate Change published the Fourth Assessment Report. Guide was completely written on December 12, 2020 the fifth anniversary of the Paris Agreement. It has been under continuous revision to include the most recent relevant information. It was completely updated after the IPCC published AR6 WGI Climate Change 2021: The Physical Science Basis on August 9, 2021. Since then AR6 WGII Climate Change 2022: Impacts, Adaptation and Vulnerability, AR6 WGIII Climate Change 2022: Mitigation and AR6 Synthesis Report 2023 have been published.
All references (except for a few very good books) are available in web sites published on the internet free of charge. Only web sites sponsored by reputable organizations are used.
The Guide is organized into a Front Matter (includes three Prefaces), and 27 Chapters. Each of the elements can be downloaded independently.
Note that there is an 'Update Log' provided after the Chapter downloads where the history of the editing is briefly described.
IMPORTANT: The last updates were made: February 25, 2024 PLEASE CHECK!

This essay reflects my personal view of how special our planet is and how wonderful it is to be alive on it. Humans must take responsibility for taking care of Earth and all life on it. We are able to do this. This is our opportunity to be contributors. As far as we know "Life is a once in a lifetime experience". We should make the most of it.
Climate changes today are still caused by natural forces such as changes in Earth’s orbit and volcanoes; but, the immediate causes are human activities – release of greenhouse gases and changes in land use.
While natural forces caused very significant climate changes in the past, with catastrophic impacts to all life on Earth, human activities now promise to cause equally significant climate change with equally serious impacts.
The difference is: Humans can prevent significant climate change from happening at all.
