‘Hurricane Harvey offers a glimpse of a likely global future; a future whose average temperatures are as different from ours as ours are from those of the last ice age.’ |
This is a manmade climate-related disaster. To ignore this ensures our greatest challenge goes unanswered and helps push the world towards catastrophe
In 2016 the US elected a president who believes that human-driven global warming is a hoax. It was the hottest year on record, in which the US was hammered by a series of climate-related disasters. Yet the total combined coverage for the entire year on the evening and Sunday news programmes on ABC, CBS, NBC and Fox News amounted to 50 minutes. Our greatest predicament, the issue that will define our lives, has been blotted from the public’s mind.
This is not an accident. But nor (with the exception of Fox News) is it likely to be a matter of policy. It reflects a deeply ingrained and scarcely conscious self-censorship. Reporters and editors ignore the subject because they have an instinct for avoiding trouble. To talk about climate breakdown (which in my view is a better term than the curiously bland labels we attach to this crisis) is to question not only Trump, not only current environmental policy, not only current economic policy – but the entire political and economic system.
It is to expose a programme that relies on robbing the future to fuel the present, that demands perpetual growth on a finite planet. It is to challenge the very basis of capitalism; to inform us that our lives are dominated by a system that cannot be sustained – a system that is destined, if it is not replaced, to destroy everything.
To claim there is no link between climate breakdown and the severity of Hurricane Harveyis like claiming there is no link between the warm summer we have experienced and the end of the last ice age. Every aspect of our weather is affected by the fact that global temperatures rose by about 4C between the ice age and the 19th century. And every aspect of our weather is affected by the 1C of global warming caused by human activities. While no weather event can be blamed solely on human-driven warming, none is unaffected by it.
We know that the severity and impact of hurricanes on coastal cities is exacerbated by at least two factors: higher sea levels, caused primarily by the thermal expansion of seawater; and greater storm intensity, caused by higher sea temperatures and the ability of warm air to hold more water than cold air.
Before it reached the Gulf of Mexico, Harvey had been demoted from a tropical storm to a tropical wave. But as it reached the Gulf, where temperatures this month have been far above average, it was upgraded first to a tropical depression, then to a category one hurricane. It might have been expected to weaken as it approached the coast, as hurricanes churn the sea, bringing cooler waters to the surface. But the water it brought up from 100 metres and more was also unusually warm. By the time it reached land, Harvey had intensified to a category four hurricane.
We were warned about this. In June, for instance, Robert Kopp, a professor of Earth sciences, predicted: “In the absence of major efforts to reduce emissions and strengthen resilience, the Gulf Coast will take a massive hit. Its exposure to sea-level rise – made worse by potentially stronger hurricanes – poses a major risk to its communities.”
To raise this issue, I’ve been told on social media, is to politicise Hurricane Harvey. It is an insult to the victims and a distraction from their urgent need. The proper time to discuss it is when people have rebuilt their homes, and scientists have been able to conduct an analysis of just how great the contribution from climate breakdown might have been. In other words, talk about it only when it’s out of the news. When researchers determined, nine years on, that human activity had made a significant contribution to Hurricane Katrina, the information scarcely registered.I believe it is the silence that’s political. To report the storm as if it were an entirely natural phenomenon, like last week’s eclipse of the sun, is to take a position. By failing to make the obvious link and talk about climate breakdown, media organisations ensure our greatest challenge goes unanswered. They help push the world towards catastrophe.
