In response to Ms. Paterson’s letter (Daily Bee, Feb 22): What is debatable about climate change is modeling the future rate of change. Is the rate of ocean or land temperature change by a certain date speeding up or slowing down? What should not be debated or questioned are the facts: atmospheric carbon dioxide concentrations are increasing, climate change is occurring and it is still happening faster than any other period due to human influence. Even Exxon knew in 1977 that CO2 from fossil fuel use would warm the planet and endanger humanity (Inside Climate News 9/16/15).

In the Bulletin of Science, Technology & Society 2015, Vol. 35(5-6) – “During 2013 and 2014, only four of 69,406 authors of peer-reviewed articles on global warming, 0.0058 percent or 1 in 17,352, rejected anthropogenic global warming. Thus, the consensus on AGW among publishing scientists is above 99.99 percent, verging on unanimity. The peer-reviewed literature contains no convincing evidence against AGW.” In another earlier published article, Env. Res. Let. 8 (2013) 024024 – “We analyze the evolution of the scienti?c consensus on anthropogenic global warming in the peer-reviewed scienti?c literature, examining 11,944 climate abstracts from 1991–2011 matching the topics ‘global climate change’ or ‘global warming’. Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research.” We can all reduce, recycle and reuse.
