Speculative Climate Warnings

I feel obligated to point out (once again) the unsupported bias that PAW continues to show in its Inbox. In your May 2025 issue I read “Climate Warnings,” which is prominently displayed over part of two columns. This letter, as with other climate warning letters, contains no proof (or even strong evidence) that human activity is causing global climate change, yet it appears to be arguing that that is the case. In fact, the three bullet items that are emphasized in the letter use the phrases “could act like the glass in a greenhouse,” “could be catastrophic,” and “predict a global surface warning” instead of the phrases “do act like the glass in a greenhouse,” “are catastrophic,” and “show actual global surface warming” or something similar. All three of these claims are speculative, not evidential.
