Global Warming
on: October 11, 2009, 07:06:10 AM
Hottest Year so far was?
1998 not this year or last year.
http://news.bbc.co.uk/2/hi/science/nature/8299079.stm

So what happened to it getting hotter and hotter?
Good read this article.

I think I agree with it not being us, well it is not all us. Yes CO2 levels and what we do to the world is NOT a good thing and we need to keep things down and a do a better job looking after the world but are we destroying the polar ice caps to the scale we are seeing? No, I do not think so.
I agree that the world has cycles and recent times have just been hotter and I agree that there will be colder as well. Things will freeze up and temperatures drop. Another Ice Age will not happen soon and before that the world was like an entire tropical island when the Dinos walked the earth but I think the world does indeed have its hot and cold cycles.
After all we do call it mother earth, lol.

I am sure if things suddenly cool and have a cool period it will still be down to us causing harm to the world from some people.

On another note I still find it interesting how it is you and me, our fault. We are doing the worst damage to the world and we are the ones told to turn off our TVs and we have to pay more taxes and what not. BOLLUX, sort out the companies and the governments themselves who do 1000 times more damage then we do.

Sam stop being a dick, Nexus didnt suggest any such thing and tbh writing anything about global warming is quite a challenge, anyone who doesnt think so is a leading figure in the subject, or does not have a full grasp of the bigger picture. Its like trying to make a decent global weather forecast, you can get a rough idea but its still going to be wrong in places. And I dont claim to have the facts before anyone says anything of the sort.

The world does indeed have cycle, but therere cycles within cycles etc. Ultimately I dont think it matters so long as human kind gets its act together. But I dont think we will, I really do believe the analogy of humans being like a virus on the earth is pretty true. When you consider our advances in the last 150-200 years, the resource usage, and the speed at which this is increasing, I cant help but feel as a virus wed be in the final stages before the host dies. It scares the crap out of me, considering whats happened so far has occurred in what by todays standards is only 2 lifetimes.

Im not being a dick, Im just amazed an intelligent and educated man things global warming isnt caused by us. I dont want to have to lump Nexus in with George Bush and Glenn Beck.

Youd be amazed at the number of "intelligent and educated" doctors and professors of environmental sciences that are skeptics of some sort or another regarding global warming/climate change then. I certainly wouldnt want to lump then in with the likes of George Bush, considering theyve spent decades researching related subjects, rather than getting 2nd hand information from the media.

Let the flaming commence.

its all cycles.. we have some of the hottest sun spots coming our way.. a few hundred/thousand years & it will be cooler anyway.

What happens then? global cooling & everyone is forced to use co2 stuff? & taxed if they dont have big carbon footprints?

probably that is about how stupid all these hippies running the country are.

The UKs entire CO2 emissions are less than the emissions from the worlds 15 Biggest ships, so me turning my tele off standby is going to help isnt it.

Can you back that up with facts as that does seem a rather remarkable statement to make.

Its a media report, rather than a scientific report, so read into it what you will. Wasnt too hard to find either.

The answer is in the article, were in the down part of a natural global cycle which is cancelling out global warming temporarily.

Both sides have very different forecasts. The Met Office says that warming is set to resume quickly and strongly.

It predicts that from 2010 to 2015 at least half the years will be hotter than the current hottest year on record (1998).


Of course being the Met office your guess on this is as good as mine. Overall temperature trends are still up though, and, if this is right, are going to get worse.

you cant believe many scientific reports either, as their budgets depend on climate change.

Carbon credits and swaps is a whole new multi euro/pound/dollar industry now - too much revenue being generated to go back!

Theres no doubt that climate change is happening though. But the extent to which it is happening depends on how much money is changing hands.

They mostly know what affects the system, and have been fairly good at predicting it. Where they have gone wrong is underestimation and local effects which can be difficult.

There are certainly enough of us to put a spanner in the works, we have been doing that for at least hundreds of years. We need to change how we affect the system, there is plenty of power available, all we need to do is change the sources.

It relates to sulphur output, not to CO2 output of the ships. Sulphur dioxide isnt a greenhouse gas, quite the reverse, it cools down the earth by reflecting light back into space.

Eliminating it might reduce effects on health and acid rain but, if anything. its going to increase global warming.

a more relevant link I found that page

as I understand it (limited, I did one module in meterology and atmospheric physics at uni but by no means an expert) the climate averaged over the whole planet is relatively easy to predict compared to local effects, since to predict the latter you have to take a great many more initial conditions into account.
