The debate over climate change by people who disbelieve the overwhelming amount of evidence by saying we need more reminds me of an old construction joke.

A worker fell off a high rise and was heard to say as he passed each floor, “So far so good.” It’s the same as continuing to accumulate repetitive evidence on the heat records for each year. Just as the worker went by each floor, with each passing year’s heat records, the deniers say it’s not so bad.

Environmental scientists are worried it may already be too late to avoid many of the disastrous changes predicted years ago. If we acted now, we may have broken bones but no splat!
