Very disappointing. Can you dilute the problem with a little dihydrogen oxide?

they are destroying US climate science on purpose, and it hurts my heart. but take it from an MIT-trained nerdass:

all most of us need to know is that we have to stop burning stuff

stop burning stuff for heat

stop burning stuff for make car go

stop burning stuff for power

So basically, no-one thinks it's Tylenol.

According to this at ArsTechnica, many anti-vaccine groups are peeved at Kennedy Jr. for not linking autism to vaccines, e.g. –

"We didn’t wait 20 years for Bobby to finally speak and then get served Tylenol as an answer,"

(Tylenol isn’t likely to be an answer either!)

Anti-vaccine groups melt down over RFK Jr. linking autism to Tylenol

“THIS WAS NOT CAUSED BY TYLENOL” Kennedy’s anti-vaccine group retweeted.

Australia’s new emissions target of 62% to 70% reduction by 2035 is a big step up on the previous goal of 43% by 2030.

While a lot of Aussies hoped for a bigger number, this is MUCH more ambitious than New Zealand’s 2035 target of 51% to 55% reduction.

Among the attempts to create hagiographic eulogies of Charlie Kirk, I’ve seen more than a few people suggest that Kirk should be respected for being willing to talk to “those who disagree with him” as a sign that he was engaging in good faith.
