Global warming: Our Readers conduct Part 2 of the interview with John Christy

J.C. Regarding the Hockey Stick, I indicated on the record in 2001 that I thought it was not a good representation of NH temperature over the past 1000 years. I am even more convinced of that statement now that studies have shown it was based on a poor mathematical technique which inappropriately gave weight to proxies which were not good representatives of temperature (among other problems.)

Q: What is your best guess for the percent of global warming seen in the 20th century due to CO2 and aerosol emissions from humans?

J.C. CO2 acts to warm the atmosphere and aerosols act to both warm and cool the atmosphere. I can only guess (I say guess because no one knows - i.e. there is no thermometer that can measure the cause of a temperature change). Using the UAH temperature trend of +0.14 C/decade since 1979 I would guess a quarter to a half of that amount is due to the net of CO2 and aerosols.

Q: How would you change gov. funding for climate research?

J.C. Observations, observations, observations. Reduced emphasis on modeling.

Van Jones: 'Higher Energy Costs Are Unavoidable'

Of course, Jones loves hyperbole like the other climate change prophets. “If we do nothing, the ensuing climate catastrophe will wreck our economy — including wreaking havoc on our food production systems. All credible scientists agree on this point.”

ANIMAL AUTOPSIES IN GULF yield a mystery. “The vast majority of the dead animals that have been found — 1,866 birds, 463 turtles, 59 dolphins and one sperm whale — show no visible signs of oil contamination.”

Climate Lessons: Wiping the Floor with Albert Gore: sensible DVDs or videos on climate for use in schools

It is a criminal offence to show Gore's propaganda piece, 'An Inconvenient Truth' in schools in England or Wales, without at the same time pointing out some of its more blatant errors or deceptions (1). Elsewhere in the world, there may be no such protection afforded to pupils and staff.
