To the editor:

Climate change due to human activity has become a well-accepted phenomenon among climate scientists. Now the debate among scientists has shifted to how severe the consequences will be, and how long before human society will collapse if nothing is done.

The scientific consensus is that human-caused climate change is causing and will continue to cause extreme high temperatures, melting polar ice, higher sea levels and temperatures, and extreme weather events. The impact is and will continue to be famines, water crises, health risks from heat and drought, extinction of species, spread of disease, and economic and political collapse.

Scientists get the picture, but distressingly, many of our policymakers are lagging behind.

One example: I attended a listening session at Afton City Hall last Saturday, and was sadly disappointed to hear House 54B Rep. Tony Jurgens say that he does not believe in human-caused climate change.

Considering that we are at a crisis point and the consequences of inaction are dire, we need our leaders working on solutions, not questioning the veracity of hard scientific evidence. History has shown us that past civilizations collapsed when their leaders were oblivious to obvious looming cataclysmic events.

A cataclysm is looming now.

Jurgens and others with his views need to stop listening to denialist hacks, figure it out and get on board or step aside and let those who believe in science do the job, because the evidence is mounting that this crisis will be immense, that it is near-at-hand, that it will impact each one of us. It needs to be dealt with now.
