Even Hansen is over-reacting to these e-mails, in my opinion.
This is deliberate output of a paid network of climate deniers, deliberately out to screw up the Copenhagen talks.
The real story here is that this cherry picked information from years of correspondence probably did not come from an unassisted private hacker.
A private hacker would have had to comb through years worth of email files to find these apparently damning quotes. The software that the intelligence agencies use to monitor email traffic could have done this in a few minutes, maybe in a few seconds.
So, this appears to me to likely be information from an intelligence service, likely leaked in collusion with the paid denier network funded ultimately by the fossil fuel industries.
The size of this network is much larger than direct funding from ExxonMobil would suggest.
From the Union of Concerned Scientists report from 2007:
Smoke, Mirrors & Hot Air
How ExxonMobil uses Big Tobacco’s Tactics to Manufacture Uncertainty on Climate Science
In 2005, the end use combustion of ExxonMobil’s products—gasoline, heating oil, kerosene, diesel products, aviation fuels, and heavy fuels—resulted in 1,047 million
metric tons of carbon dioxide–equivalent emissions.
If it was a country, ExxonMobil would rank sixth in emissions...For example, the George C. Marshall Institute, a leading paid climate denier think tank, has received six hundred thousand dollars directly from ExxonMobil.
But they have received something over six million dollars from a network of conservative foundations including the Scaife and Bradley foundations. This network of conservative foundations often funds the same organizations that ExxonMobil does, including the Heritage Foundation, the American Enterprise Institute, and other leading denier organizations:
Funding for the George C. Marshall Institute:
Exxon Mobil Corporation $640,000
Lynde and Harry Bradley Foundation $3,590,303
Sarah Scaife Foundation $2,785,000
Funding for the American Enterprise Institute:
Exxon Mobil Corporation $1,625,000
Lynde and Harry Bradley Foundation $~17,000,000
Scaife Foundations $~8,000,000
Funding for the Heritage Foundation:
Exxon Mobil Corporation $460,000
Lynde and Harry Bradley Foundation $~14,000,000
Scaife Foundations $~24,000,000
To see that this network of conservative “charitable” foundations often fund climate denier think tanks in an apparently coordinated manner, go to the Media Matters Action Network, and do a few searches on this list of ExxonMobil funded think tanks in the Union of Concerned Scientists report:

In essentially all of their public statements, ExxonMobil is lying, in my opinion.
They are funding a network of information laundering sites, and are doing so in concert with a much larger network of “charitable” foundations that support conservative causes including the opposition of climate change.
This conservative “charitable: foundation network is a much larger, and much better funded network, as a few searches on Media Action Network shows – and it funds global warming denier information laundering sites in concert with ExxonMobil.
