In June 1988, James E. Hansen made one of the first assessments that human-caused warming had already measurably affected global climate. Shortly after, a “World Conference on the Changing Atmosphere: Implications for Global Security” gathered hundreds of scientists and others in Toronto.
Who first used climate change?
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.
Who is known as father of climate change?
James Edward Hansen (born March 29, 1941) is an American adjunct professor directing the Program on Climate Science, Awareness and Solutions of the Earth Institute at Columbia University.

Who is most responsible for climate change?
Rich countries, including the United States, Canada, Japan and much of western Europe, account for just 12 percent of the global population today but are responsible for 50 percent of all the planet-warming greenhouse gases released from fossil fuels and industry over the past 170 years.
When did we first know about climate change?
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified.
Who discovered greenhouse effect?
John Tyndall set the foundation for our modern understanding of the greenhouse effect, climate change, meteorology, and weather. But did he ‘discover’ it? 160 years ago, on 18 May 1859, the Irish physicist John Tyndall wrote in his journal ‘the subject is completely in my hands’.

Who contributes the most to climate change 2020?
China is the world’s largest contributing country to CO2 emissions—a trend that has steadily risen over the years—now producing 10.06 billion metric tons of CO2.
Why did global warming start?
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the “greenhouse effect”1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
Who is the world’s number one polluter?
China was the biggest emitter of fossil fuel carbon dioxide (CO2) emissions in 2020, accounting for 30.64 percent of global emissions. The world’s top five largest polluters were responsible for roughly 60 percent of global CO2 emissions in 2020.
