Interesting to note that....

It is around 45 degrees Celcius that photosynthesis ceases, even for well irrigated plants. If the heatwave continued for more than a week or so, trees would start to change to autumn colors, and leaves would start to fall off trees. I don't know if that happened to any great extent, but it could have.

WOW.
