Joanne Nova claims that Global Warming has been disproved and lists 9 “Major Flaws” – or so she says.

  1. The missing heat is not in the ocean.
  2. Satellites show a warmer Earth is releasing extra energy to space.
  3. The models get core assumptions wrong – the hot spot is missing.
  4. Clouds cool the planet as it warms.
  5. The models are wrong on a local, regional, or continental scale.
  6. Eight different methods suggest a climate sensitivity of 0.4°C.
  7. Has CO2 warmed the planet at all in the last 50 years? It’s harder to tell than you think.
  8. Even if we assume it’s warmed since 1979, and assume that it was all CO2, if so, feedbacks are zero — disaster averted.
  9. It was as warm or warmer 1000 years ago. Models can’t explain that. It wasn’t CO2.  The models can’t predict past episodes of warming, so why would they predict future ones?
