Keith Briffia, who advised the IPCC regarding climate change, had his e-mails hacked (along with others).
Check out what he wrote in one of his e-mails:
"I believe that the recent warmth was probably matched about 1000 years ago" (there were men back then, but no factories, LOL).
and then Malclom Hughes (also an IPCC shill):"I tried to imply in my e-mail, but will now say directly, that although a direct carbon dioxide effect is still the best candidate to explain this effect, it is far from proven. In any case, the relevant point is that there is no meaningful correlation with local temperature.
These are both IPCC alarmists caught red-handed when there e-mails were hacked.
