How much proof do the global warming deniers need?

"When you stare out over the wave of Weather of Mass Destruction we are unleashing, who looks crazy – the protesters, or the people who have yet to join them?"

Originally published in the UK Independent, by Johann Hari


Thank God man-made global warming was proven to be a hoax. Just imagine what the world might have looked like now if those conspiring scientists had been telling the truth. No doubt Nasa would be telling us that this year is now the hottest since humans began keeping records. The weather satellites would show that even when heat from the sun significantly dipped earlier this year, the world still got hotter. Russia's vast forests would be burning to the ground in the fiercest drought they have ever seen, turning the air black in Moscow, killing 15,000 people, and forcing foreign embassies to evacuate. Because warm air holds more water vapour, the world's storms would be hugely increasing in intensity and violence – drowning one fifth of Pakistan, and causing giant mudslides in China.

The world's ice sheets would be sloughing off massive melting chunks four times the size of Manhattan. The cost of bread would be soaring across the world as heat shrivelled the wheat crops. The increased carbon dioxide in the atmosphere would be fizzing into the oceans, making them more acidic and so killing 40 per cent of the phytoplankton that make up the irreplaceable base of the oceanic food chain. The denialists would be conceding at last that everything the climate scientists said would happen – with their pesky graphs and studies and computers – came to pass.

This is all happening today, except for that final stubborn step. It's hard to pin any one event on man-made global warming: there were occasional freak weather events before we started altering the atmosphere, and on their own, any of these events could be just another example. But they are, cumulatively, part of a plain pattern where extreme weather is occurring "with greater frequency and in many cases with greater intensity" as the temperature soars, as the US National Climatic Data Centre puts it. This is exactly what climate scientists have been warning us man-made global warming will look like, to the letter. Ashen-faced, they add that all this is coming after less than one degree of global warming since the Industrial Revolution. We are revving up for as much as five degrees more this century.

Yet as the evidence of global warming becomes ever clearer...
