Scientists have investigated all potential causes of climate change and concluded that human activity is responsible for modern warming, not the end of the Little Ice Age. Climate change has adverse impacts on plants and agriculture, including through its influence on extreme weather events.
Scientific evidence shows that climate change is driven by human activities, as recognized by the world’s authoritative scientific bodies such as the U.N.’s Intergovernmental Panel on Climate Change, the U.S. National Academy of Sciences and the U.K. Royal Society. These scientific bodies, composed of experts in the field of climate science, have concluded that climate change is predominantly driven by human emissions of greenhouse gases. The “World Climate Declaration” group, largely composed of non-experts, relies on several inaccurate claims about the science to arrive at an alternative conclusion.
“The scientific content is completely inaccurate, undocumented, and fails to bring proof for its claims. The ending of the Little Ice Age in 1850 has no logical link with the fact that the Earth is warming now. Most past climate variations have been slower or less intense as the present one, and if they were as fast or severe they brought about mass extinctions in the biosphere. No explanation or proof is brought on the implausibility or inaccuracy of climate models (whose accuracy or uncertainty is precisely quantified and makes their use better than just random guesses).”
