Anyway, rail should be subsidised if necessary. In fact after British rail was privatised it was getting more government subsidy that before!
In places where there are no trains there isn't than much traffic.[/quote]
Support this. They was an allegation of suppression of a report, and it is dealt with here
This report is a joke. It is not written by climate scientists, it debunks nothing. Realclimate end with..
"Finally, they end up with the oddest claim in the submission: That because human welfare has increased over the twentieth century at a time when CO2 was increasing, this somehow implies that no amount of CO2 increases can ever cause a danger to human society. This is just boneheadly stupid.
So in summary, what we have is a ragbag collection of un-peer reviewed web pages, an unhealthy dose of sunstroke, a dash of astrology and more cherries than you can poke a cocktail stick at. Seriously, if that’s the best they can do, the EPA’s ruling is on pretty safe ground.
If I were the authors, I’d suppress this myself, and then go for a long hike on the Appalachian Trail….
The PETM (Paleocene-Eocene Thermal Maximum) was a rapid heating of the planet at the Paleocene-Eocene boundary. Global temperatures rose by 6°C over 20,000 years, 55 million years ago. Many animals became extinct. The causes are not completely understood and are probably multiple, but what we do know is a lot of carbon was released into the atmosphere. Dunno about ice ages, I dont think there were any in the Paleocene or Eocene. Anyway, nobody really know how much of the warming and CO2 were cause or effect. It is a complex relationship of factors not fully understood.
