Wildfires have erupted across the globe, scorching places that rarely burned before

The wildfires are part of a vicious climate cycle that releases more carbon into the atmosphere and worsens the warming.

But now the city is blanketed in haze as nearby wildfires tear through forests that have been parched by weeks of heatwaves. The fires are so big, and the winds strong, smoke is traveling as far away as Alaska. In the US, the Bootleg wildfire in Oregon has grown into a monstrous complex with its own weather, sending the dense smoke some 3,000 miles across one end of the continent to the other. New York City on Wednesday woke up to an intense red sunrise, the smell of wildfires and a thick brown haze.
