Notes: In a speech to the Foreign Relations Council in New York on June 28, 2012, Exxon CEO Rex Tillerson admitted that global warming is real. However, he stated "Changes to weather patterns that move crop production areas around — we'll adapt to that. It's an engineering problem, and it has engineering solutions."
However, Mark Lynas, who wrote the 2008 book, Six Degrees: Our Future on a Hotter Planet, would probably strongly disagree with Tillerson's assessment. In the concluding chapter on page 282, he wrote, "It should be clear that the business as usual trend (which we are currently on...) yields a chance of reaching four, five and even six (celsius) degrees of warning (above today's average global temperature) by (the year) 2100."
In 2008, National Geographic created the video, Six Degrees Could change the World, which is based on the Lynas book. The video states a 4 degree average global temperature rise by the end of this century would result (among other factors) in "West Antarctic Ice Sheet in danger of collapse as warming oceans penetrate underneath, flooding coastal cities with sea level rise."
At a five degree rise, "hundreds of millions of climate refugees are on the march searching for food and water."
At a six degree rise, "huge unihabitable areas span the entire global surface, human civilization collapses due to the pressure of conflict and diminishing resourcs."
Rex Tillerson may think that we will just "adapt" to climate change with "engineering solutions." However, as Mark Lynas came up with his projections from studying the scientific peer reviewed literature, he showed climate change could be quite chaotic for civilization. If we do not act now not to reduce the threat of climate change, the result could be very dangerous for future generations and even threaten civilization itself.
