Not saying panick, but I am saying don't go listening to politicians from either side who clearly have an agenda. Nor should you listen to studies funded by groups with agendas. Find an independent study conducted at a university. Not hard. Or better, learn about the relevant science yourself and you can draw conclusions from data that make sense.

Following up on his brilliant earlier work “The Black Swan”, Taleb has written a paper called Error, Dimensionality, and Predictability (draft version). I could not even begin to do justice to this tour-de-force, so let me just quote the abstract and encourage you to read the paper.

I don’t deny that climate changes over time — who could? So I am not a climate change denier
I don’t deny that the Earth has warmed over the last century (something like 0.7C). So I am not a global warming denier
I don’t deny that man’s CO2 has some incremental effect on warming, and perhaps climate change (in fact, man effects climate with many more of his activities other than just CO2 — land use, with cities on the one hand and irrigated agriculture on the other, has measurable effects on the climate). So I am not a man-made climate change or man-made global warming denier.
What I deny is the catastrophe — the proposition that man-made global warming** will cause catastrophic climate changes whose adverse affects will outweigh both the benefits of warming as well as the costs of mitigation. I believe that warming forecasts have been substantially exaggerated (in part due to positive feedback assumptions) and that tales of current climate change trends are greatly exaggerated and based more on noting individual outlier events and not through real data on trends (see hurricanes, for example).
Though it loses some of this nuance, I would probably accept “man-made climate catastrophe denier” as a title.

I am willing, even at the risk of the obvious parallel that is being drawn to the Holocaust deniers, to accept the “denier” label, but it has to be attached to a proposition I actually deny, or that can even be denied.
Experiments done at CERN have shown that high-energy ionizing galactic cosmic rays (GCRs) seed cloud formation in earth's lower atmosphere, and this low cloud cover reflects more solar energy than it traps, resulting in a net cooling of the atmosphere.
The solar cycles moderate the amount of these cosmic rays that can penetrate to our atmosphere.
The greater the solar output the greater shielding from these GCRs and the fewer penetrate to our lower atmosphere, which leads to diminished cloud cover and increased global warming.
When the solar output is at a minimum more GCRs penetrate to our lower atmosphere which results in greater cloud cover and a cooling of the atmosphere.
We are coming into a period of lower solar output and can expect global cooling as a result.
Atmospheric CO2 has minimal effect on the climate at current levels; the CO2 levels have continued their steady rise while the climate has steadied and then cooled over the past 17 years.
Global Warming -- Research Issues
Does the Sun cause global warming or climate change?
Your chart ends at the peak of the 1965-1997 warming phase.
You will notice that atmospheric CO2 levels explain none of these; this is because CO2 has no effect on climate. Atmospheric CO2 is the result of climate change, not the driver.

I had one of my investigations take a curious turn recently. I was going to use as my springboard the most interesting 2015 paper entitled The Albedo Of Earth, by Graeme L. Stephens et al. However, a strange thing happened along the way. I got to thinking about their Figure 5, in particular Panel (a).:

The importance here is that Mr. Stephens has read the coherent rebuttal and wishes not to respond one way or another. That is a problem. Because discussions on potentiality are not limited to consensus.

Ice cores yield history of volcanic eruptions, climate effects
A new method of analyzing ice cores has allowed scientists to more precisely determine when volcanic eruptions occurred on Earth over the last 2,500 years.
