Fresh round of hacked climate science emails leaked online | Environment | The Guardian

[Mann] said, the people behind the release were "agents doing the dirty bidding of the fossil fuel industry know they can't contest the fundamental science of human-caused climate change. So they have instead turned to smear, innuendo, criminal hacking of websites, and leaking out-of-context snippets of personal emails in their effort to try to confuse the public about the science and thereby forestall any action to combat this critical threat. Its right out of the tried-and-true playbook of climate change denial."
