Climate Change and Its Impacts

A new climate change report suggests a 95% chance of Earth's temperature rising over two degrees Celsius this century, with severe impacts like heatwaves and rising sea levels. The study highlights the importance of limiting warming to two degrees, though achieving this requires major efforts. Factors like population, GDP, and carbon intensity influence climate change, with carbon intensity being a key focus for reduction. Despite challenges, technological advances and regulations can help mitigate warming, emphasizing the need for sustained global efforts.
