Record-breaking heat wave in Texas.

NYC & Chicago recording the worst air quality of major cities in the world due to wildfire smoke.

First US cases of malaria in decades.

#Climate change is the biggest public health threat humanity faces, and it's happening now.

Summers in Texas and Florida were always warm enough to support malaria transmission.

…and the vectors & malaria were there for quite awhile before malaria was eliminated, all while the climate was warming.

It’s odd to find two clusters with no history of travel at once, but odd things happen sometimes.

Anyway, it’s quite a leap to blame climate change for these cases.
