Testimony To Congress – US Professor

Professor Curry points out the fundamental flaw that we cannot predict future climate when we cannot predict natural climate. Natural climate could easily neutralise “global warming”.

SPACE AND TECHNOLOGY OF THE UNITED STATES HOUSE OF REPRESENTATIVES

” …If all other things remain equal, it is clear that adding more carbon dioxide to the atmosphere will warm the planet. However the real difficulty is that nothing remains equal, and reliable prediction of the impact of carbon dioxide on the climate requires that we understand natural climate variability properly. Until we understand natural climate variability better, we cannot reliably infer sensitivity to greenhouse gas forcing or understand its role in influencing extreme weather events. Natural climate variability refers to forcing from the sun, volcanic eruptions and natural internal variability associated with chaotic interactions between the atmosphere and ocean…. “

Watch it here – Prof Curry starts 15 minutes in – questioning starts 32 minutes in.
Prof Curry is a reformed Alarmist.
There is also testimony from a tame Democrats scientist, following the party line, and from Bjørn Lomborg who pedals his usual commercial global warming is real but it costs to much to fix arguments.
