In 1896, a seminal paper by Swedish scientist Svante Arrhenius first predicted that changes in atmospheric carbon dioxide levels could substantially alter the surface temperature through the greenhouse effect. In 1938, Guy Callendar connected carbon dioxide increases in Earth’s atmosphere to global warming.
When did climate change first become a problem?
Scientists first began to worry about climate change toward the end of the 1950s, Spencer Weart, a historian and retired director of the Center for History of Physics at the American Institute of Physics in College Park, Maryland, told Live Science in an email.
How did global warming start?
The early onset of warming can be attributed to the initial rises in greenhouse gases caused by the Industrial Revolution. The turning point in our climate was probably also influenced by recovery from a massive volcanic eruption (Tambora) in 1815, which caused the infamous “year without a summer” in Europe.

Does war contribute to global warming?
Militaries consume enormous amounts of fossil fuels, which contributes directly to global warming. If the US military were a country, for example, it would have the 47th highest emissions total worldwide. Bombings and other methods of modern warfare directly harm wildlife and biodiversity.
What are the top contributors to climate change?
Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.
