Whose understanding?
by Jarl Ahlbeck
"Consistent with our understanding of natural fluctuations..." After digging for many years deep into the climate change scientific literature, I think that the understanding of both natural and anthropogenic climate change still is very poor. Yes, carbon dioxide should cause some warming. But without positive feedbacks (amplifying) from water vapour and clouds the effect should be minute. These feedbacks are poorly known. Not even the total sign is known. It may be even negative (damping). When the El Nino 1998 was very strong (high temperature), the greenhouse industry (Kevin Trenberth) claimed that carbon dioxide emissions causes strong El Ninos. Now when the situation is normal, nobody claims that anymore. The long-term warming started almost 200 years ago, long before the SUV-era that now (fortunately) is coming to an end.
