Heatwave. It’s all people are talking about. It’s as if a glass dome’s been lowered over the Broads. There’s no escape. It hasn’t rained for a month and Norfolk is already the second-driest county in the country. People seem weighed down. Water levels have dropped leaving ugly stains on banks and sluices, lawns and heaths are yellow and crunchy underfoot, birds mammals and insects are flocking to water. The blackberries are ripe a month early. We’ve bought fans from Amazon and lie sweltering on the bed and sofa with our hot computers on our laps. If this is what it’s like here imagine what it’s like in Delhi, says S., or Riyadh. What’s it going to be like in fifty years? A hundred?
The Anthropocene, environmental scientists call it: the age in which humans have become the main cause of planetary changes. The effects of the horrifying feedback loop we’ve created is now happening in real time they say. The papers report droughts, floods and wildfires all over the world. Polar ice is melting and reflecting less heat from the sun, oceans are expanding and absorbing more. Freshwater around the Earth is drying up, mountains are breaking apart as their glaciers melt. As the seas warm and rise, earthquakes, hurricanes and floods are becoming commonplace. Crops are baking in the sun. Overheated forests are starting to give off rather than absorb carbon dioxide, raising temperatures further.
We can still ignore it for now, still enjoy ourselves, worry about our careers and relationships, raise children. But unless we arrest the loop, extreme weather will dwarf our lives. People all over the world will die of thirst, heat stress and starvation. There’ll be wars for resources. Coastal cities will be wiped out. Millions will flee the uninhabitable lands around the equator. The global north will become more and more fortified against refugees.
