Better and longer satellite data about the Sun Improved assessment: a) no observed trend in solar irradiance since 1978 using high quality inter-calibrated data; b) spectral information c) solar magnetic flux model rather than proxy data; d) re-evaluation of variations in Sun-like stars. No observed trend in this data. Solar forcing much less than greenhouse gases.

Explosive Volcanic Eruptions: Proof of Fast-Response Climate Change Due to Forcing Changing forcing changes the temperature (and water vapor, etc.). If volcanoes can cool, then GHG must warm….
Deltas and megadeltas: hotspots for vulnerability Nearly 300 million people inhabit a sample of 40 deltas globally, including all the large megadeltas. Average population density is 500 people/km2 with the largest population in the Ganges-Brahmaputra delta, and the highest density in the Nile delta. Many of these deltas and megadeltas are associated with significant and expanding urban areas
