More scientific caution at earthtimes.org?

I was pleased to see the word "claim" in this headline at earthtimes.org: "Claim: Global warming will trigger illness".

They've also recently used that word in other headlines, including this one: "Claim: global warming decreases hurricanes".

Note that the word has been absent from many headlines in the past, such as this one: "Scientists find proof that carbon dioxide is leading to global warming".
