Earth, Two Degrees Warmer

A recent study in Nature Climate Change predicts a 95% chance of Earth's temperature rising over 2 degrees Celsius this century, with severe consequences like heatwaves and rising sea levels. The study highlights the importance of limiting warming to 2 degrees, though achieving this goal is challenging. Factors like population growth, GDP, and carbon intensity influence climate change. While population growth in sub-Saharan Africa will have minimal impact, reducing carbon intensity is crucial. Technological advances and regulations will play a key role in determining future outcomes. Major efforts are needed to meet climate goals.

What is the significance of the two-degree Celsius benchmark in climate change discussions?

• It represents the average temperature increase since the 1900s.

• It is the threshold beyond which severe climate impacts are expected.

• It is the maximum temperature increase allowed by international law.

• It is the average temperature increase per decade.

According to the new study, what is the likelihood of the Earth's temperature rising by more than two degrees Celsius by 2100?

• 100%

• 50%

• 95%

• 5%

Which region is expected to contribute the least to CO2 emissions by 2100 despite population growth?

• Sub-Saharan Africa

• Asia

• Europe

• North America

What is the main focus to reduce greenhouse gas emissions according to the study?
