How has the Paris Agreement impacted global heat extremes?
Since the Paris Agreement was adopted in 2015, global efforts to cut emissions have led to a significant reduction in projected heat extremes. Studies indicate that the world is now on track for a 2.6°C increase by 2100, down from earlier estimates of 4°C. This shows that international climate action has made a real difference in moderating the worst-case scenarios of global warming.

What does 2.6°C warming mean for different countries?
A 2.6°C rise in global temperatures will have varied impacts across nations. Some countries, especially small island nations and those dependent on ocean ecosystems, will face more severe heatwaves and environmental stress. Larger, industrialized nations may experience increased heat days, droughts, and health risks, but the effects will differ based on local climate, infrastructure, and adaptation measures.
-
Which nations are most at risk from rising heat days?
Small island nations and low-lying coastal countries are most vulnerable to rising heat days, as they face the largest increases despite contributing little to global emissions. These nations are already experiencing more frequent and intense heatwaves, which threaten their ecosystems, agriculture, and livelihoods. Developing countries with limited resources for adaptation are also at higher risk.
-
Can current climate efforts prevent dangerous heat waves?
While recent progress has slowed the pace of warming, current efforts alone may not be enough to prevent the most dangerous heat waves. Continued and increased action is needed to reduce emissions further and implement adaptation strategies. Without stronger measures, the risk of severe heatwaves and related climate disasters remains high.

What are the biggest challenges in fighting climate change?
Major challenges include political will, economic interests, and global cooperation. Many countries still prioritize short-term economic gains over long-term climate goals. Additionally, inequalities between nations can hinder unified action. Overcoming these barriers is essential to achieving meaningful progress in reducing heat extremes and protecting vulnerable populations.
