In 2010 Hansen said that there would artic ice in the summer by in the next 5-10 years.

Googling arctic summer ice "James Hansen" "5-10 years" doesn't turn up any media article.

The sea ice actually increased.

No, it's decreasing

You might be able to cherry-pick periods of up to 7 years where there was an apparent increase, but that would be dishonest.

In 1988 he predicted that the great lakes would dry up.

This article I believe I can find.

The quote is "At the same time, heat would cause inland waters to evaporate more rapidly, thus lowering the level of bodies of water such as the Great Lakes."

Not "dry up"

And it's in an article that talks about Hansen but also Dr. Syukuro Manabe, Dr. George Woodwell, and Dr. Michael Oppenheimer. The quote isn't attributed to Hansen.

Hansen predicted in 1988 that lower Manhattan would be underwater in 30 years (by 2018).

He's probably referring to a misquote of Hansen who was speculating off the cuff about the impacts if CO2 were doubled overnight. https://skepticalscience.com/Hansen-West-Side-Highway.htm

The media are serial liars. Global warming is bullshit.

It appears to me that the denialists are the liars. And that makes a lot more sense, because there's money on that side.
