There is a climate change consensus that climate change is made primarily through the use of fossil fuels.....
There is no such consensus....I remember the letter from some 30,000 scientists denying such a consensus...recently read a report from 500 scientists in disagreement......science is not percentages, anyway!
I suspect you're standards for what constitutes a climate scientist may be too loose, how about we just trust in the Canadian Meteorological and Oceanographic Society (CMOS) and their position statement on climate change?
* Earth's climate---arising from the interaction of the atmosphere, ocean, ice, land surface, and living things---undergoes changes from both human activity and natural causes.
* Knowledge of climate change is based on observations of the climate and scientific understanding of physical, chemical, and biological processes.
* Humans influence the climate through changing the atmosphere's composition, primarily through emissions of greenhouse gases as a result of combustion of fossil fuels and deforestation. Carbon dioxide (CO2) is the dominant human-emitted greenhouse gas. The current CO2 concentration is approximately 50% above the pre-industrial levels.
* Human activity has been the main cause of the observed increase in temperature since the middle of the 20th century. The four recent years (2015-2018) have been the warmest years on record for global surface temperature. A long-term warming will continue in the 21st century, although individual months or years will also be affected by natural climate variations.
* Changes in climate result in responses in average and extreme temperature and precipitation, as well as in wind, sea level, snow and ice cover. There are also numerous other responses, such as ocean acidification and deoxygenation. Many of these responses, including those attributed to human activity, have already been observed and are predicted to continue in the future.
