The warmest days in modern history occurred across the planet this month.
Scientists say the planet is entering a multiyear period of exceptional warmth. “We are going to see things happen this year around Earth that we have not seen in modern history”. Expect damaging heat waves, floods, droughts, wildfires and hurricanes.
Greenhouse gas emissions, mostly from the burning of fossil fuels, have already heated the Earth by an average of 1.2 degrees Celsius compared with preindustrial levels. Now a powerful El Niño system in the Pacific Ocean is releasing a torrent of heat into the atmosphere.
In the past week Delhi recorded its wettest July day in 40 years, North Africa has seen temperatures near 50C, Beijing residents flocked to underground air raid shelters to escape the heat, and floods carried away cars in Spain.
But even more shocking: the record-breaking air temperatures are the result of only 1% of the extra heat trapped inside the climate system by all the carbon pollution we produce. The vast majority of that heat is going into the ocean, which is also reaching record high temperatures.
Sea surface temperatures in the northern and central Great Barrier Reef are now 2 degrees Celsius hotter than the 2002-2011 average. In June, the North Atlantic Ocean reached its highest temperatures in over 170 years of record-keeping, surpassing the average by as much as 5 degrees Celsius.
The need to decarbonise the world economy can be seen as the biggest collective action in human history. This requires the remaking of the world’s entire energy and transportation systems, not to mention vast overhauls of modern life. And it all needs to happen as a matter of urgency as the planet heats up.
