Global warming new thread

All of the energy ever created on earth came from the sun, or the solar system in general.

Solar energy, combined with biology has generated, over thousands of millions of years: trees on land, plankton in seas which have not only created organic fuels but also carbonic rocks (e.g. limestone). And there is a lot of it; each lump, grain and drop, was generated by the sun. Over 1000s of millions of years. All that energy has been trapped in mineral form. Like a battery.
What happens, do you think, when that energy (carbon) is released within a few hundred years as mankind elects to burn coal, oil and make cement from limestone?

Tinfoil hatter nonsense. It's basic science that increased CO2 traps more heat. Refute the science if you wish, but "they are all lying" just gets you laughed at.

ror the last 60 years or so, people have been using things called "thermostats". You might want to look them up. My heating is on 24/7/365, controlled by them.

Carmen not sure to be honest . Its a long time since I studied this area. All I know is that it has changed in relation to polar and magnetic North. You seem to know more than me do you have a link handy so I can brush up my knowledge. ( genuine request)

If you have an OS map it tells you the deviation at time of publishing and the rate of change so you can work out what the deviation will be when you use it.

On a nautical chart it looks like this

this means is that in the year 1999 Magnetic North would have been 12.5 degrees to the West of True North. But it also indicates that there is an annual increase in this variation of 2′ (minutes) every year. If it was E it would decrease.

To work out the variation today you have to add 50 minutes.

Or roughly 13.5 degrees. So if my compass says I’m heading 340 degrees M I plot 353.5 on the chart. T

If I need to head 340 T, I have to steer 326.5 on the compass

Deniers might love the carboniferous period but again it takes a long time. Long time since school so needed a bit of a refresh. It lasted for ~60m years ~360m years ago. CO2, ice cover+ sea level variations in a sort of cyclic manner leading seams of various substances. Coal mostly formed in the latter part of the period. Land masses not where they are today, More on the wiki.

So for some millions of years plant life locks up CO2 as coal and peat etc. We come up and burn up a lot of it in a few hundred years. Actually as far as coal is concerned a lot of the "good stuff" has been used up.

Something else goes on as well. Simply explained here - why we need to dig to explore the past. Plant life and conversion of C02 to other substances did the same thing before we really interfered
 
Another element in the mix is the amount of methane being released in Arctic Russia where some of the world's biggest hidden sources of this greenhouse gas, in the Yamal and Gyda peninsulas, mysterious giant craters have been appearing in the north Siberian permafrost.

Scientists have long recognized the possibility that global warming could ignite a “methane bomb” in the Arctic: the rapid release of huge amounts of methane from thawing permafrost and underwater methane hydrates. Such a release could trigger extinction-level warming.

I'd love to know why he gets a free pass to be abusive to people, and when someone (such as me!) reports multiple such posts, he gets to carry on being abusive while I get banned from posting.

The moderators on this forum are a joke, it's as bad as the SF forum

you got banned from posting because you were abusive

I have never been abusive
 
It's all me me me with not a thought given to people living in Northern and southern extremes who will finally have an ice free and warmer climate to enjoy their lives a bit better
 
The thing is, whether man made climate change is a thing or not, I tend to give more thought to the wider question. Namely, if climate change is a thing, regardless of cause, what's the plan to try and mitigate and in reality, what positive impact are said changes likely to have.

There seems to be a consensus, ok maybe not a consensus but more than a few folk saying it, that we'll need oil for the next 30-50 years. At a basic level and if forced one way or the other, this assertion is either fact or not fact. If it's fact, then what the feck are these just stop oil protestors wasting their time for?

Up here in Scotland, we hear year in year out about how well coastal renewables could do. However in reality, there doesn't appear to be any truly concerted effort to implement this on a large scale. Is that because it's known these solutions would actually be pants, or because 'big business' is protecting its fossil fuel interests, or a combo of both?

And look at it this way. Let's say those who panic about all this are right. Let's say, in reality, we should be making massive significant changes as quickly as possible regardless of what government, business and the public want. What would that actually look like?

Because of the world we've created, the infrastructure, the products, the general way society functions, our economy, it's cloud cuckoo land to assert this can all be changed quickly. It will take decades regardless of the rationale behind such a timescale.

If it's too long it's too long. If it's written in the proverbial stars that we're all doomed by not acting much more quickly, then it's written in the stars.

That's not apathy, it's realism.
