The linked article, not from BP, says that BP accepted there was a problem in 1997. This may be before I started thinking it was serious. BP has its own ethical and environmental problems (negligence leading to large Prudoe (sp?) Bay oil pipeline failure, and I think a refinery explosion that killed people (?).
I have my own ethics problems: my large 2002 Camry is out of gas, I live in a larger house than I need, I fly a lot, and I tend to drive (120 to 140 miles) to the airports rather than take the van shuttle.

Here in my part of the heartland, it is 10 deg, and will be cold all week, but the winter has still averaged out warmer than average. I tried to skate on my shallow pond 4 times last week and it only actually skated 1 time...it was too thin. I'm going to miss either snow or ice late this week because I'll be in warm and sunny Santa Barbara, ironically working on climate-related scientific drilling from the Ross Ice Shelf. The one time I got to go to Antarctica, I left NY 4 days after the Blizzard of 96, and it was warmer (by a lot) at latitude 78 deg south than at 41 deg N...at least around the bare black volcanic cinders of McMurdo station...a 10 minute walk away at Scott Hut it was much colder by the ice-covered McMurdo sound.

Introduction

British Petroleum appears to be fundamentally changing the way it does business. In a groundbreaking speech by CEO John Browne in May, 1997, (1) British Petroleum announced to the world its decision to accept that climate change is occurring and its intention to do something about reducing BP's contributions to it. This action has attracted attention from President Clinton, BP's competitors, environmentalists, and the business press; it also has the potential to raise, considerably, public expectations regarding the actions of other multinational companies.

Browne’s speech was a breakthrough for four reasons.

BP was the first multinational corporation other than re-insurance companies to join the emerging consensus on climate change.
BP committed to reduce greenhouse emissions from all of its own business operations.
The company proposed to join international efforts to reduce greenhouse emissions, and
Solar energy was officially “moved up to the big table”, as president of BP Solar Peter Beadle explains— on par with BP’s three other lines of business—exploration, oil, and chemicals. "
