Questions & Answers

Q: Why did early scientists start considering the causes of climate change?

Early scientists like Louis Agassiz and Joseph Fourier noticed changes in glaciers and temperature that led them to investigate the causes of climate change.

Q: Why was Guy Callendar's research largely dismissed?

Callendar's research was dismissed because he was not a meteorologist, and some scientists questioned the accuracy of his measurements. They also believed that variations in carbon dioxide levels could not significantly impact climate.

Q: What led to a widespread acceptance of climate change?

Charles Keeling's groundbreaking measurements of atmospheric carbon dioxide levels, known as the Keeling Curve, garnered attention and acceptance from climate scientists and world leaders.

Q: What are some proposed solutions to combat climate change?

Solutions include reducing greenhouse gas emissions, implementing clean energy solutions, and finding ways to remove existing emissions. It also involves adapting to a warmer world and supporting vulnerable communities.
