Obama has his work cut out, to repair the damage caused by the previous administration in many areas. In addition he has a global environmental criss to deal with, with species extinction happen at 1000 times the normal rate. partly through GW and partly due to other causes.
Has there been a tougher challenge for a new president?

I'm pleased you said that! I was reading an article the other day saying that in the 70s, the EU passed a clean air bill. Since they did that, EUROPEAN AVERAGE TEMPERATURE has risen 0.5°C per decade. That was 40 years ago - that's an AVERAGE rise of 2°C in the period. Why? Clean air means more sunlight can reach the surface, resulting in increased warming. End of. They have also ADMITTED that climate models do NOT correctly model what has been occuring in the EU over that period. When I find the article, I'll be sure to post a link to it. You like New Scientist - here ya go! This is what the IPCC were saying back in 1992. http://www.newscientist.com/article/mg13318050.600-clean-air-will-expose-europe-to-global-warming-.html
See how their position changes based on the current political climate (no pun intended)? This is what they're saying today: http://uk.news.yahoo.com/22/20090118/twl-environment-us-climate-fog-1202b49.html That's close to the article I read. The BBC ran a similar article.
I presume you're familiar with what happens when data points become skewed in a dataset, that the average can be adversely affected? It would most certainly explain that hockey-stick graph (up to around 2000 at least) where it inexplicably starts rising faster than the past. As I raised at the time, WHAT HAPPENED AROUND THE 70s TO CAUSE THIS SUDDEN INCREASE? Here is our answer: the clean air bill in Europe. It is far too co-incidental for it to be a mistake. Something else not mentioned is the loss of temperature measuring equipment from the former Soviet Union. They had a network of 15,000 stations. Now they only have 5,000, and most of those lost were located in some of the coldest parts of the planet. This will also have the effect of skewing data. Vulcan. |

Yes the Topic is more about species extinction as a result of 'all' causes. The biggest causes of species extinction are not to do with GW. It may well be the main cause in time though.
New Scientist is better than Conspiracy Monthly.
This post wasn't about global warnming but if you insist.
From your link, the bit you conveniently left out...
So thats Western Europe, rather than the entire globe, so localised. There will always be varaibles such as this and the recent La Nina event. The overall upward trend marches on though. By the way, never a good idea to listen to 'A' scientist, listen to them all when they've formed a consensus.
See how their position changes based on the current political climate
Which is of course nonsense, they were talking about a localised event and also acknowledged the warming over the rest of the planet.
It was also 1992 Vulcan a full 17 years ago. Knowledge has increased, models are better, and short term variables have come and gone.
Pity you weren't interested in the poor animals that are becoming extinct [through many causes] like the fact that there are now only white rhinos left that are of non breeding age.

I am interested in them, but I can't do anything about it.
Instead of burning money and resources fighting wars, we'd do better try and ?help? the planet a bit IMHO. GW is one small piece of the overall eco-system. We need to clean up a lot more than we have, in every respect. Best regards, Vulcan. |

Depends on the severity of the issue, where the priority should lie. The ice caps are melting, it is really happening, we must do what we can to stop adding our contribution to the problem. It isn't really something any serious [unbiased] person debates any more, the evidence keeps coming in that we are responsible, it can't all be wrong or a con trick. Species extinction is a serious issue, estimated to be a 1000 times the natural rate of species loss. The northern white Rhino now only exists as examples beyond breeding age. This is a tragedy. Plenty of other species are in dire straits also, because we take their habitat, hunt and generally drive them into extinction. And yes climate change is adding to the issues these animals face. |
