If natural conditions are just right, the Earth will warm. The Earth is warming, so the natural conditions must be just right.

IPCC authors do not make the final edits to the chapters they author, instead the final text conforms to the UN objective of building support for world taxation and energy rationing.

Thousands of experts on a variety of scientific topics signed the Global Warming Petition Project (opposing climate action), so scientific consensus on climate change must be pretty shaky.

MIT Climate Scientist Richard Lindzen says, "CO2 is hardly poisonous, on the contrary it's essential for life on Earth and levels as high as 5,000 ppm are permitted in submarines and the space station"

In the interglacial warm periods increasing CO2 concentrations sometimes lagged increasing temperatures, so today's rising temperatures also have some other cause.

The idea that all life could be wiped off the planet because I take hot showers and drive to the grocery store is absurd.

Scientific consensus was wrong in the past about things like gravity or Earth as the center of the universe, so the scientific consensus today can't be trusted either.

IPCC is always talking about estimated risk and margins of error, but scientific facts must be 100% certain.

Human contributions of CO2 to the atmosphere are tiny compared to natural sources, so our influence on climate can only be negligible also.

Scientists can't even predict next week's weather much less next year's climate.

What Greta Thunberg says about climate can't be trusted, she is just an emotional little girl with exploitive parents.

There is no "correct" temperature for Earth, so it's not something we need to worry about.

The "hottest" year claims were based on statistically meaningless differences that fell within the margin of error.

Geologist Bob Carter calls climate science, "kindergarten science" and suggests the results are completely meaningless.

The EPA has a graph showing Heat Index values were much higher in the 1930s than they are today, so this rising temperature story is bogus.

Climate model predictions are just the opinions of experts with a conflict of interest because they are paid to produce the models.

Ocean sea level data is notoriously difficult to measure, therefore rising trends in the data are not real.

Columbia University physicist William Happer says, "demonization of carbon dioxide is like the demonization of the poor Jews under Hitler" (2014)

Implementing even modest climate policies will eventually lead to even bigger restrictions of freedom and ultimately to a socialist government.

CO2 only stays in the atmosphere 4 years, so if we stop emitting now, then nature will absorb the extra quickly.

History shows that warmer eras meant better crops and food stability and therefore had fewer wars, so a warming planet could mean a more peaceful planet.
