This analysis of the 4th National Climate Assessment is a great explanation of my general views on climate change. My thoughts are:
- Earth's climate is changing, and it has never been static
- Human activity isn't contributing much to the change
- A general warming trend would be good for humanity
- Therefore, we shouldn't disrupt our energy production and economy in an attempt to manipulate earth's climate
I highly recommend reading the whole analysis.
Due to the considerable doubt about the magnitude of the human contribution to climate change it would seem foolish to destroy the fossil fuel industry, throwing millions out of work and crushing the world's economy with higher energy prices. Anything this foolish and destructive should certainly wait until (and if) the climate models used to create the projections used in NCA4 volume two are validated and produce a much tighter set of projections than seen in Figure 1. However, the chapter on adaptation is still valid. If some climate changes are harmful in some areas, these ideas are useful. Regardless of how much climate change is man-made, communities should adapt by improving their infrastructure to resist climate-related threats. Coastal areas should improve storm-surge and flood barriers, the western U.S. should improve their forest management to make fighting forest fires easier, every part of the U.S. should improve their surface water drainage, etc. Adaptation is an obvious thing to do, the benefits of mitigation (reducing fossil fuel use) are far more speculative and much less likely to be effective (May 2018). Bjorn Lomborg has also written extensively about this in his book Cool It and in articles such as this one. NCA4 reports that construction of adaptation infrastructure in the U.S. has increased since 2014, which is a good thing (page 53, Report-in-Brief).
