&gt;Humans produce immense amounts of CO2, CO2 in the atmosphere increases the temperature of the planet. It&#x27;s as simple as that.<p>CO2 is a green house gas - good job mr. high-school physicist - now show me the temperature projections along with human CO2 production graphs and estimated impacts and error margins and past model prediction performances vs measured data. You know the actual things that matter for policy implications. See that&#x27;s where things go beyond high school.
