Research over decades prove climate change is man-made

We’re clearly affecting our planet. It’s time to act like it.

Jon Buss refers to man-made climate change as mythical (“The left beats the ‘climate change’ drum for power,” published Nov. 23). Apparently he has deemed himself an absolute authority on this matter. I would love to see his credentials to make such a statement but I think those may be the mythical part.

Jon has long made his opinion clear that he thinks Democrats are in league with the devil and anything they do must be evil. I, on the other hand, did a simple search for fact based evidence that supports the claims and came up with nine independent lines of evidence that irrefutably make the case.

1. Simple chemistry: burning carbon based materials releases carbon dioxide, research beginning in the 1900s.

2. What we burn, research beginning in the 1970s.

3. Measuring CO2 in the air and trapped in the ice (levels higher than anything in millions of years.)

4. Chemical analysis: CO2 comes from burning fossil fuels, research beginning in the 1950s.

5. Basic physics: CO2 absorbs heat in the atmosphere, research since the 1820s.

6. Monitoring climate conditions, research beginning in the 1930s.

7. Ruling out natural factors, research beginning in the 1830s.

8. Employing computer models of nature vs. human causes, research beginning in the 1960s.

9. Tens of thousands of scientists from many countries have amassed overwhelming evidence: Humans are the main cause of climate change.

The claims Jon makes that weather has always changed is one of the few things Jon got right. What he also got right is that this is just a sliver of time in the history of our planet, but in that sliver of time (approximately 150 years) our climate has seen change that has taken tens of thousands of years by natural means.

I won’t bother to address Jon’s other claims, some of which may actually have some merit.
