Climate change, a global issue that is primarily driven by the burning of fossil fuels, is causing a progressive increase in the frequency, duration, and severity of heatwaves. This dramatic shift in weather patterns is particularly noticeable in the Western regions of the world. Although there may be occasional cool days and heavy snow, the general trend observed from data is one of global warming. Since 1880, the average global temperature has risen by 2 degrees.

This increase in temperature is not a static phenomenon. Predictions indicate that if carbon emissions continue at their current rate, unchecked, we could see a rise in global temperatures by approximately 5 degrees by the end of the century. More alarming still is the worst-case scenario, which predicts an increase of up to 8 degrees.

The escalation of heatwaves is not a new trend. Indeed, since the mid-1960s, the frequency and duration of these extreme weather events have been on the rise. Comparatively, there has been an almost double increase in the number of heatwave days globally since the 1980s.

Rising temperatures pose a significant threat to both humans and ecosystems. Potential health risks associated with extreme heat include dehydration and cardiovascular problems. The danger to outdoor workers is increasing, recreational activities are being disrupted, and pest infestations are damaging our forests. Moreover, there has been a noted increase in the frequency and severity of wildfires.

California and the western United States are a prime example of regions that are increasingly suffering from the effects of climate change. The accumulation of greenhouse gases in these regions has led to increasingly frequent and lethal heat waves. This increase in temperature is not just a regional problem. Nineteen of the 20 hottest years on record have occurred since 2000, a fact that underscores the continued rise in global average temperature due to our unabated burning of fossil fuels.

Extreme heat events, like the one that occurred in the Pacific Northwest in 2021, have dramatic and deadly consequences. This particular event resulted in the death of hundreds of people and an estimated 1 billion sea creatures. If we continue at our current rate of carbon emissions, events like these could become 20 times more likely. As such, it is imperative that we tackle the issue of climate change head-on, reducing our dependence on fossil fuels, and mitigating the catastrophic effects of global warming.
