What I have found interesting in this thread, and in the broader discussion of climate change is the new position taken by the faction that used to be called deniers. Five to ten years ago it was the claim that there was no global warming. There were vehement diatribes that the temperature data being produced by the US and the UN and multiple other sources were made up, what is now called "fake news" and that there in fact was no warming at all.
There was a huge attempt to falsely claim that some emails proved it was all cooked up data. This was labelled
"Climategate" by the deniers. Click on the link to see what leading US legislators jumped on this as
proving that global warming was a "hoax".
Now it seems everyone sees that the temperature data is real, both for the atmosphere and the oceans. And so the argument shifted to, yes it is getting warmer but it has nothing to do with human activity. It was all natural cycles and the ever changing climate alterations, and when was the last ice age. Some few here are still denying humanity's role or minimizing it.
But most of the posters are admitting that the climate is being impacted in a significant way by man. Some say, well we shouldn't do anything until China does something big, and India does something big. But at least therein is an acceptance that it is human action using fossil fuels that is causing this change. So that's progress.
I'd only add that if you believe in leadership and stewardship by our country in the world, that is a specious argument. China's economy is booming but very young and that nation is still climbing out of third world status. And they in fact have
made major efforts to improve their environmental impacts. Sadly those changes are coming too slowly. Our nation has gone backwards in the last 3 years having abandoned goals and abrogated international agreements.
As to the initial question, and I worried about climate change? Not for myself or my children or grandchildren. We are secure here and will not be significantly impacted. But my view is broader than that. I am concerned for the devastation that a foot of ocean rise will cause to arable land in the third world. I am concerned about the loss of coral reefs and alterations in the phytoplankton which may destroy the fish life in our oceans causing starvation, but not here. Some experts have predicted that resulting famines will spark major international and regional wars. And I understand that what we do now will effect the world for decades. And what we fail to do will also have consequences.
So I am heartened that at least most of us are finally on board that warming is real and needs to be addressed. Overton's window has shifted.
