Because we listen to turkeys.
We are turkey whisperers.

Ontario's wild turkeys, sometimes seen feeding on farmers' fields or gracing dinner tables, are on the trot thanks to climate change.
And therefore we need to reduce our carbon dioxide(CO2) emissions?
Why?
The built-in assumption is that human emissions of CO2 are driving climate change.
Where’s the proof for that assumption?
So?
Do scientists go where the data leads?
Between 1920-1944 CO2 went up 7.4 ppm.
Between 1920-1944 GMT went up .43C
Between 1991-2015 CO2 went up 46.5 ppm
Between 1991-2015 GMT went up ?
GMT - Global Mean Temperature
How much should ‘?’ be to convince you that CO2 drives climate and we are in deep doo-doo?
IF CO2 drives temperature is it reasonable to assume the relationship is linear?
Can we divide the temperature by the rise in CO2 to establish the heating power of 1 ppm of CO2?
.43/7.4 = .06C/ppm
Can we then multiply that result by the ppm rise in the last 25 years to give us the value of ‘?’
.06C/ppm X 46.5ppm = ?
And if the measured temperature rise is less than that what would you conclude?
CO2 does not drive temperature.
Or
CO2 drives temperature in a non-linear manner.
What manner would that be?
Something like a drug addict who needs a higher dose to get the same ‘high’?
DO we need more and more CO2 in the air to get the same temperature rise as in the past?
Is there then a limit to the temperature rise that CO2 can cause?
Some scientists think that that is the case.
Are we there yet? What is that limit?
Is it relevant to ask if the planet has been that warm in the past?
If it has, does that not imply that there is no tipping point because there was no runaway global warming in the past at higher levels of CO2? Hello, we are here.
So what do scientists say about the Earth’s temperature in the past? Has it been much warmer than now when CO2 was at pre-industrial levels (280 ppm)?
YES
Can you see why some scientists don’t think CO2 drives temperature at all.
Can you see a relationship for the last 600 million years?
So what is ‘?’
Linear = 2.7C (.06C/ppm X 46.5ppm)
Measured = .45C
Is it fair to conclude that CO2 does NOT drive climate change?
Here is the data. Datasets are in the links.

If Ontario wild turkeys moving north are evidence of global warming then what do we conclude when an Arctic animal shows up in Seattle?
Must be true, right?
Never fear, the Beaver is here!
It is really all about the beaver.
We got this.
And you thought I was just another pretty face!
