We
are now in a low CO2 period
20th century increase
insignificant
4 Jul 10 - "Looking back 600 million years, atmospheric carbon
dioxide was likely 18 times today’s concentration during the
Cambrian period when life’s diversity was at its greatest expansion
(red circle)," says Burt Rutan. "It was 4 times the current level
when the dinosaurs were killed by an asteroid. The only other
extended time CO2 was low, (like today) was a period 300 million
years ago."
"In the big picture we are now in a low CO2 period," says Rutan.
"The 20th century increase shows as an insignificant dot
at this scale."
"Do we risk runaway greenhouse
warming if our CO2 concentration gets too high?" asks Rutan. "It has
never significantly driven temperature before."
"Venus may have runaway greenhouse
warming, but its CO2, at 96.5% is 2,500 times the level of CO2 in
the earth’s atmosphere."
Rutan will give
a version of this presentation at the International Experimental
Aircraft Convention, world's largest convention, at 11:15 am, July
31st, Pavilion 7.
Who is
Burt Rutan?
Burt Rutan was Time
magazine's "100 most influential people in the world, 2004" and
Inc. Magazine's "Entrepreneur of the Year." Newsweek
called him "the man responsible for more innovations in modern
aviation than any living engineer." (After this, Time may
call him the greatest persona non grata of the year.)
Rutan has received hundreds of awards including: Presidential
Citizen's Medal, Two Collier Trophies, Academy of Achievement Golden
Plate and the Charles Lindbergh Award. He has developed 44 new
aircraft types since 1972 including; Voyager (1986 RTW-non
refueled), SpaceShipOne (2004 Funded by Paul Allen, winner of
X-prize) and the first commercial spaceship - SpaceShipTwo (2009
Funded by Sir Richard Branson).
