Misleading claims about weather, electric vehicles spread online

Posts misleadingly claim human-caused CO2 emissions are too small to warm planet

A graphic shared over a thousand times on Facebook claims the concentration of carbon dioxide (CO2) released by humans into Earth’s atmosphere is too small to cause climate change. This is misleading: the claim miscalculates the human input and scientists agree that CO2 has a big impact on the planet’s temperature. The level of CO2 in the atmosphere has grown sharply due to humans burning fossil fuels and is driving global heating.
