I've often warned the real risk of AI images is giving people the ability to deny the real images more than making them believe things that aren't true.
Trump claims a video showing people throwing bags out a White House window is "probably AI generated." Doocy then plays the clip for him. Trump still insists it's AI.

Rising global temperatures can influence the timing of events, such as when crops are ready to plant and harvest and when flowers and trees bloom.
One example is the timing of the peak cherry tree blossom in Kyoto, Japan, where records stretch back to the ninth century — that’s over 1200 years.

Man, now Saudi Arabia has apparently been caught editing official COP29 drafts, maybe granted edit access by the COP presidency, Azerbaijan. Rough.
