change, Russia’s boreal forest is going up in smoke. Large blazes in the Siberian republic of Sakha have broken Russia’s record for a single summer’s emissions of atmosphere-warming carbon from wildfires. Since June, they have emitted about 505 million tons of carbon, according to the European Union’s Copernicus Atmosphere Monitoring Service—more than Mexico’s total carbon output from all sources in 2018. The smoke from Siberia has covered at least 1.5 million square kilometers, twice the size of Texas, NASA estimated, and even traveled 4800 kilometers to the North Pole. Elsewhere, Algeria, Canada, and Turkey have also battled unusually large fires this month. In Greece, a fire that raged across the island of Evia caused the country’s “greatest ecological catastrophe of the last few decades,” Prime Minister Kyriakos Mitsotakis said on 12 August. Even Hawaii suffered its largest ever wildfire this month. The cumulative effect is to put the world on pace for the highest carbon emissions from fires in this century, according to the Global Fire Emissions Database.
