"Due to their unprecedented nature, these heat waves are usually linked to very severe health impacts, and can be disastrous for agriculture, vegetation and infrastructure. We're not built for them, and we might not be able to adapt fast enough," says Lamont climate scientist @kornhuber.bsky.social.

The immediate loss of life and property is of course the main concern right now. But when the smoke clears, the risk does not end, unfortunately. If you have access to N95 masks and indoor air filters, now is the time to use them to reduce exposure to toxic air.
