What are the health impacts of extreme heat?
Extreme heat can lead to a range of health issues, including heat exhaustion, heatstroke, and exacerbation of pre-existing conditions like cardiovascular and respiratory diseases. Vulnerable populations, such as the elderly and those with chronic illnesses, are particularly at risk. The report highlights that heat is one of the deadliest extreme weather events, emphasizing the need for awareness and preparedness.

How is agriculture affected by climate change?
Climate change disrupts agricultural productivity through increased temperatures, altered precipitation patterns, and more frequent extreme weather events. These changes can lead to reduced crop yields, affecting food security and livelihoods. Farmers may need to adapt their practices to cope with these challenges, including selecting more resilient crop varieties and improving water management.

What strategies can be implemented to manage extreme heat events?
Effective strategies to manage extreme heat include improving urban planning to increase green spaces, implementing heat action plans, and enhancing public health messaging. Communities can also invest in cooling centers and provide resources for vulnerable populations to stay safe during heatwaves. Policymakers must prioritize climate action to address the root causes of extreme heat.

What are the long-term effects of extreme heat on food security?
Long-term exposure to extreme heat can severely impact food security by reducing crop yields and increasing food prices. As agricultural systems struggle to adapt, food availability may decline, leading to increased hunger and malnutrition. Addressing climate change is crucial to ensuring sustainable food systems and protecting vulnerable populations from food insecurity.

How does fossil fuel consumption contribute to climate change?
The burning of fossil fuels releases greenhouse gases into the atmosphere, which trap heat and lead to global warming. This process exacerbates climate change, resulting in more frequent and severe extreme weather events, including heatwaves. Transitioning to renewable energy sources is essential for mitigating these impacts and protecting public health and the environment.
