How long have we known about the greenhouse effect?
In 1895 Swedish scientist Svante Arrhenius discovered that humans could increase the greenhouse effect by making carbon dioxide through burning fossil fuels. He kicked off 100 years of climate research that has given us a sophisticated understanding of global warming.
How has the international community responded to this knowledge?
Although we have known about the potential impacts of the greenhouse effect for over 100 years, the process of attempting to gear the international community towards climate action has only really happened in the last twenty years and the process has really gained momentum in the last 8 years.
