NOT true science.
That 97% consensus?
A group of mostly social “scientists” at a couple of Australian universities. It was a reply by email poll, so only true activists answered it.*
Does the climate change? Yes. Has it gotten 1 degree Celsius warmer since 1880? Yes. All of these things are measurable.
However, the idea that doubling the carbon dioxide load in the atmosphere will cause the global temperature to go up by 8 to 10 degrees Celsius is laughable... It is not happening. They tried to say the heating was taking place first in the deep oceans, but THEN when they were all toasty warm, the air would finally catch up and get really hot.
And they call THIS science? No, just no. It isn’t.
And guess what? It is now believed by many that the low levels of CO2 in the atmosphere is an ice age phenomena that actually harms plant life, and more CO2 might mean a greening of the Earth; more green than the past 3 million years or so. A very strong theory, full of facts and data, is being formulated on this.
*Things you’ll NEVER hear about on TV.
An international team of 32 authors from 24 institutions in eight countries has just published a study titled “Greening of the Earth and its Drivers” in the journal Nature Climate Change showing significant greening of a quarter to one-half of the Earth's vegetated lands using data from the NASA-MODIS and NOAA-AVHRR satellite sensors of the past 33 years. The greening represents an increase in leaves on plants and trees. Green leaves produce sugars using energy in the sunlight to mix carbon dioxide (CO2) drawn in from the air with water and nutrients pumped in from the ground. These sugars are the source of food, fiber and fuel for life on Earth. More sugars are produced when there is more CO2 in the air, and this is called CO2 fertilization.
About 85% of the Earth's ice-free lands is covered by vegetation. The area of all green leaves on Earth is equal to, on average, 32% of the Earth's total surface area - oceans, lands and permanent icesheets combined. “The greening over the past 33 years reported in this study is equivalent to adding a green continent about two-times the size of mainland USA (18 million km2), and has the ability to fundamentally change the cycling of water and carbon in the climate system,” says lead author Dr. Zaichun Zhu, a researcher from Peking University, China, who did the first-half of this study as a Visiting Scholar in the Department of Earth and Environment at Boston University, USA, together with Prof. Myneni.

The amount of CO2 is 4/100ths of one percent.
The amount of Oxygen is around 21%.
The amount of Nitrogen is 79%.
The CO2 level means nothing more than a fart in a mitten.
