Understanding the Factors Behind Rising Globe Temperatures and Severe Heatwaves
Heatwaves, periods of higher-than-average temperatures in a specific region, are becoming more frequent and longer, posing a significant threat to communities worldwide. These extended periods of high temperatures, particularly in dry regions, contribute to higher risks of wildfires, as evidenced in areas like Siberia.
Recently, temperatures in Lytton, British Columbia, Canada, skyrocketed above 49°C, and hundreds of wildfires popped up across the country. In June 2021, a six-day long heatwave occurred on the west coast of the US, with historic high temperatures recorded in seven different states.
Scientists project that extreme temperatures will increase at higher rates in the future as greenhouse gases continue to be released worldwide. The greenhouse effect, caused by an increase in greenhouse gas emissions since the industrial revolution, is the primary cause of global warming and temperature increase. Greenhouse gas emissions, including carbon dioxide, methane, and nitrous monoxide, are primarily caused by burning fossil fuels, agriculture, land use, and various industries.
Climate change is the root cause of global warming and is linked to the increased intensity and frequency of heatwaves and extreme climate events. Droughts will become more common due to global warming, which can make hot temperatures even higher as drier grounds absorb more sunlight.
Preparation for summer seasons is crucial to mitigate the effects of heatwaves and climate change events, such as droughts and wildfires. It's critical for governments and individuals to prepare measures and safety conditions during summer seasons. Heatwaves tend to occur more frequently in dry conditions with low humidity, but can also have a large impact in high humidity conditions, especially in cities, on livestock, and wildlife.
Wildfires could indirectly endanger residents by affecting infrastructure and preventing people from accessing help. Mortality rates tend to increase during periods of heatwaves and extreme climate events, especially for the elderly and more vulnerable citizens. Heatwaves can have significant impacts on populations, livestock, and wildlife.
The exact impact of climate change on the occurrence of heatwaves is difficult to measure. Heatwaves occur due to high atmospheric pressure that forces warm air downwards and prevents it from rising, creating a heat dome with air trapped underneath. Atmospheric moisture plays a role in the occurrence of heatwaves, with heatwaves more frequent in dry conditions and potentially having a large impact in high humidity conditions, especially in cities, on livestock, and wildlife.
In conclusion, as heatwaves and wildfires become more frequent and severe due to climate change, it is crucial for everyone to take steps to prepare for these events. By understanding the causes and effects of heatwaves and wildfires, we can work together to mitigate their impact and protect our communities.
