Dedicated to the balanced discussion of global warming
US Senate Committee on Environment & Public Works – March 21, 2007
Senator Boxer chairs the US Senate Committee on Environment and Public Works. She gave an opening statement upon the arrival of Mr. Al Gore, former Vice President of the United States. Her statement confirms her belief in global warming, that it is caused by human activity, and that it is imperative that the US take steps to prevent it.
Mr. Vice President, we are honored and privileged to have you here with
us today, to discuss one of the most important challenges facing
humankind – global warming.
Professor Roger Ravelle, who began making the first measurements of CO2 in the atmosphere, was your spark. And from that, you became a spark that has ignited the global warming debate in
Personally, I believe your work has made all the difference for the future of our planet and for our children and grandchildren.
The recent report by the Intergovernmental Panel on Climate Change
(IPCC), written by hundreds of scientists from around the world and
reviewed by many more, including NOAA scientist Susan Solomon, confirms
conclusively that the earth is warming due to human activity.
The IPCC report tells us that “warming is unequivocal,” that CO2
levels are higher than anytime in the past 650,000 years and that there
is a 90% certainty that most of the warming is due to human activity.
It also tells us that since 1961 the average temperature of the ocean
has increased, that the ocean is absorbing about 80% of the heat added
to the climate system and that the ocean is becoming increasingly
acidic from absorbing carbon dioxide.
But the President of the National Academy of Sciences, testified before
Congress that “changes in the Sun cannot explain the warming
observed over the past 25 years.”
But the IPCC says that “losses from the ice sheets of Greenland and
Antarcticahave very likely contributed to sea level rise over 1993-2003.”
The time for action is now and the next decade will likely tell the
tale of whether we, as a species, have been able to act decisively to
protect our planet.
