"There is no climate emergency," the Global Climate Intelligence Group (CLINTEL) said in its World Climate Declaration (pdf), made public in August. "Climate science should be less political, while climate policies should be more scientific. Scientists should openly address uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real costs as well as the imagined benefits of their policy measures."

A total of 1,609 scientists and professionals from around the world have signed the declaration, including 321 from the United States.

The coalition pointed out that Earth's climate has varied as long as it has existed, with the planet experiencing several cold and warm phases. The Little Ice Age only ended as recently as 1850, they said.

"Therefore, it is no surprise that we now are experiencing a period of warming," the declaration said.

Warming is happening "far slower" than predicted by the Intergovernmental Panel on Climate Change.

"Climate models have many shortcomings and are not remotely plausible as policy tools," the coalition said, adding that these models "exaggerate the effect of greenhouse gases" and "ignore the fact that enriching the atmosphere with CO2 is beneficial." For instance, even though climate alarmists characterize CO2 as environmentally-damaging, the coalition pointed out that the gas is "not a pollutant."

Carbon dioxide is "essential" to all life on earth and is "favorable" for nature. Extra CO2 results in the growth of global plant biomass while also boosting the yields of crops worldwide.

CLINTEL also dismissed the narrative of global warming being linked to increased natural disasters like hurricanes, floods, and droughts, stressing that there is "no statistical evidence" to support these claims.
