Our Proverbial Titanic: Turning Hard Starboard
As we witness the European Union election results and the recent US Supreme Court's Chevron ruling, it feels like our Titanic is making a hard turn to the right. This shift carries deadly implications for our well-being, leaving lawyers and judges in charge of our health—a move that could be considered a death sentence. But let's momentarily indulge in the luxury of the first-class menu, savoring the Mallard Duck, while we assess the grim realities of our mid-year review.
The Climate Crisis: Lingering Heat Waves
June marks the halfway point of the year, and it's time to confront a dire reality: climate change is making heat waves linger longer, exacerbating the effects of extreme temperatures. Last summer, oppressive heat waves swept across large parts of the planet, loitering for days or even weeks. According to a recent study published in Science Advances, each decade between 1979 and 2020 saw the rate at which heat waves travel slowing by about 5 miles (8 kilometers) per day. Heat waves now last about four days longer on average.
Wei Zhang, a climate scientist at Utah State University and one of the study's authors, emphasizes the severe public health impacts of these prolonged heat waves. The longer people are exposed to life-threatening temperatures, the more dangerous it becomes. This slowdown in heat wave movement also affects economic productivity as workers slow down in extreme heat, and it dries out soil and vegetation, harming crops and raising the risk of wildfires.
Regional Differences and Atmospheric Changes
The study found that heat waves are particularly lingering in Eurasia and North America and traveling farther in South America. Scientists have detected a larger pattern of weakening air circulation and upper atmosphere winds, like the jet stream, during summer in higher northern latitudes. This weakening could cause extreme weather events to stall and overstay their welcome. Although more research is needed to determine the exact causes, the harmful effects remain clear.
Dr. Zhang is especially concerned about urban areas, which are often hotter due to the urban heat island effect. He suggests that cities build more cooling centers, particularly for people experiencing homelessness. While waiting for international leaders to make progress on cutting greenhouse gas emissions, local adaptation efforts are crucial to keeping people safe.
The Unseen Dangers of Moderate Heat
Let us stay in the heat of the game changer for the next decade. Climate change is killing more people than most other natural disasters combined. Research shows that it’s not just record-breaking heat waves but also the far more numerous unremarkably hot days that cause the bulk of societal destruction. Even moderately elevated temperatures—days in the 80s or 90s—are responsible for as many excess deaths as the record triple-digit heat waves, according to recent analyses of Medicare records.
A growing body of literature links temperature to cognitive performance and decision-making. Hotter days lead to more mistakes, including among professional athletes, increased local crime, and more violence in prisons. Social media analysis even suggests that a hotter world is likely to be more irritable, error-prone, and conflictual.
Adaptation and Resilience: The Path Forward
At present, our social and economic systems are ill-prepared to adjust to the accumulating damage wreaked by climate change. The impact of climate change on us depends on the choices we make as individuals and as a society. Whether a hot day leads to mild discomfort or widespread mortality comes down to human decisions—like whether to install air-conditioning and collective decisions about the availability of insurance, hospital beds, and work procedures.
Climate change is a complex phenomenon, and its ultimate costs will depend on how quickly we transition away from fossil fuels and how well we adapt our social and economic systems to the warming that is already underway. A proactive stance toward adaptation and resilience is essential for safeguarding both physical and financial security, from homeowners to Fortune 500 company leaders. It is vital for ensuring that economic opportunities do not fray for those climbing the lower rungs of the economic ladder.
Conclusion: Bon Appétit
So, as we enjoy our Mallard Duck, let's not forget the pressing issues that demand our attention. Our proverbial Titanic is indeed changing course, and we must act swiftly and decisively to mitigate the looming dangers of climate change and the implications of our political decisions. Bon appétit, but let us also prepare for the turbulent times ahead.
