Whose calculations first linked rising carbon dioxide to a warmer Earth?

Swedish scientist Svante Arrhenius was the first to calculate how changes in carbon dioxide could affect global temperature. In 1896, he estimated that a doubling of atmospheric CO2 could raise Earth’s temperature by several degrees Celsius. His work was based on the physics available at the time, and his numbers were rough by modern standards, but the core idea was remarkably prescient. Arrhenius is now regarded as a pioneer of climate change science.
