2008-JAN-12: Indonesia: A report on the UN climate conference:
"This is True #708"1
repeated a report from theSydney Morning Herald:
"Attendees at a United Nations climate conference in Bali, Indonesia,
were disturbed when they noticed that a temporary air conditioning
system set up to keep the 10,000 delegates cool not only used
ozone-destroying CFCs, but the system, which used plastic pipes, was
noticeably leaking. They counted 700 cylinders containing enough of the
refrigerant gas to cause as much damage to the atmosphere as 48,000
tonnes of carbon dioxide -- 'nearly the equivalent of the emissions of
all [of the] aircraft used to fly delegates to Indonesia'."
"This is true" titled the report: "Keep Your Cool."
They commented: "In other news, none of the attendees was able to state the
definition of 'irony'."
2008-MAR-29:Earth Hour was observed in Sydney, Australia during
the evening of
2007-MAR-31 when 2.2 million people and 2,100 businesses turned off their
lights during Earth Hour. Energy consumption in the city was reduced by
10.2% for that hour. On 2008-MAR-29, it is being observed by some cities around the
world. Citizens are urged to turn off their lights between 8 and 9 PM local
time. Brisbane, Chicago, Copenhagen, Manila, Melborne, Sydney, Toronto, Tel Aviv and other cities are
participating. More info.
2008-APR-02: Oceans' dead zones growing in size: The journal
Science reported the results of a study of oxygen-depleted zones in the
central and eastern equatorial Atlantic and equatorial Pacific. The "dead"
areas have expanded over the past 50 years. These observations were
predicted by mathematical models that linked global warming with a decline
in the level of oxygen dissolved in the oceans. As the water temperature
increases, its capacity for absorbing oxygen declines. Warming also
adversely affects currents that mix and move water from the depths to near
the surface where it can absorb oxygen. Frank A. Whitney of Canada's
Institute of Ocean Sciences said: "As oceans lose oxygen, this will
reduce habitat for many organisms. Many species will lose their deep
habitat, meaning competition will become stronger in the remaining favorable
habitat, and increased vulnerability to predation will likely occur. 2
