Unbelievable

This is Albert's F650's fault.

 

sun spots run in an 11 year cycle, and their radiation directly affects the earths's atmosphere and therefore the weather.

I blame all us American for the current solar activity. We are all just too greedy and that is making the sun all crazy and stuff.

 

So if it is all due to solar cycles then why didn't the same thing happen the last time we were in a similar solar cycle?

The fact is lots of natural things contribute to climate change.

We know that the earth's orbit around the sun isn't constant, and the temperature changes depending on whether we are closer or farther away. Also, the tilt of the axis affects temperature extremes. This is theory is called Milankovitch Cycles, and it is based on climate history and cosmology. If this is part of the problem, it could be a significant contributor, and we can't do squat about it.

The amount of ice is also a big factor since ice reflects 80% of sunlight while water and land absorb 90% of sunlight and turns it into heat. But while this is natural, we can impact this if we can find a way to lower the average global temperature by cutting greenhouse emissions. Higher temperates means less ice (duh!), so if we can slow or stop temperates from increasing it will help.

Also, underground and underwater deposits and sources of methane, a major greenhouse gas, will be released as global temps continue to rise. There is frozen methane trapped under lakes and oceans that will bubble to the surface. And in arctic climates that have been covered by permafrost for most or all of human history are melting now. That melt will also release insane amounts of methane once bacteria begins to process the soon-to-be unfrozen materials in the ground. Technically it has already begun, but it will skyrocket soon. Again, stopping temperature increases will help.

But in the end, we know that CO2 contributes to global warming. The only real question is how much. We should do what we can to curb it as quickly as possible. We already have some technology readily available to help, like compact florescent lights, hybrid cars, and alternative energy sources. And simply cutting down on our use of energy would be a big help. But we need to make a dent immediately, assuming it isn't already too late to stop it.

Will the human race be destroyed by global warming? Probably not. But it will cause serious problems. If the ice caps and glaciers melt, we're talking about current coastal land being permanently flooded. We are talking about dying crops, limited resources, overpopulation, and the inevitable wars that spring up between people fighting for those resources.

 

define "soon" you talkin' geological or human scale soon?

Yeah the frozen methane is certainly a ticking timebomb. Of course it was deposited when it froze during the last ice age. Need to collect it all up and start driving our SUVs with it. Such a course just might delay the next ice age and the certain doom for all.

Earth was overpopulated a few billion humans ago. Do I get too decide which humans are part of the "over" in the population? I say we all fight it out and the last million are the winners.

 

"Soon" as in a handful of years at most the way we are going. Soon, as in the arctic will possibly be ice free or close to it in about 4 years from now based on the past few years continuing as a trend.

Basically, the Earth wobbles on its axis on a 23,000 year cycle as well. I agree with you that there are many contributors to global warming.

In 5 billion years or so, our sun will have matured to the Red Giant stage and the Earth will be toast anyway.

Freeze, Fry or Dry: How Long Has the Earth Got?

 

Nothing like a direct answer :clown:

well then its time to start burning all the dirty coal we can so as too fill the sky with heat blocking filth.

Have you sold all your stocks and bonds and stuff in anticipation of this clatismatic event that will be upon all 7 billion of us in just over 1000 days?



Yet again what about the "hot" earth that produced all the methane that is now frozen at the bottom of the ocean. Did those cavemen's SUV finally tip the scales or did the cavemen burn the forrests to bring on the iceage. Seriously the thought that people are gonna destroy the earth in 1000+ days is just beneath you Starkiller. The possibility that the earth is getting warmer has some merit. When I was a kid the fear was an immenant Ice Age now its golbal warming - both thoughts were/are total and complete demogaguary and do nothing except line the pockets of a bunch of tree hugging PHD in search of government aid - I mean academic research funds.

FWIW the earth gets colder. The earth gets warmer. Its the nature of the beast. The 11/121/1331 year sunspot cycles explain these delta factors simply and do not require a "boogy man" in the form of industralized nations to explain whatever the eggheads decide to measure on any given day.

 

Where are you plucking this "1000 days" crap from? Are you pretending we didn't burn fossil fuels before 2008? The industrial revolution was when this began. It has been going on for roughly 2 centuries now and keeps accelerating every year.

The fact is that we know that increased levels CO2 cause the Earth to retain more heat. We simply don't know how much that contributes to modern climate change.

There is absolutely no scientific or rational doubt that humanity has changed Earth's natural environment. We know that between 1000AD and 1800AD, CO2 levels remained basically constant and never varied by more than 2.5% in that entire 8 century stretch. We know that modern CO2 levels have steadily increased by 40% since the start of the industrial age and continue to rise exponentially.

In the end, greenhouse gas levels in the atmosphere are the only thing humans can directly impact as far as global warming. So we can either choose to do something about it in the event we are part of the problem or we can ignore it entirely and just hope for the best. After all, it's not like we have anything riding on the outcome...

What's more, the things we need to do to cut our CO2 emissions would benefit America anyway. It would cut the need for imported oil, cut pollution, expand American business interests in developing alternate energy.

Yes, the Earth naturally gets warmer and colder. We all know that. The question is how much humans have thrown off the natural order of things. We already know humanity has caused all sorts of un-natural pollution, deforestation, and extinctions. So you can't pretend we can't alter the natural order of things.

 

about 4 years is just over 1000+ days

FWIW I purchased some of those floursecent lightbulbs - had a difficult to reach bulb that needed replaced and those things selling point is that they are supposed too last longer - although they were only rated like 2000 hours. The 100watt version is not even close to the real 100watt bulb it replaced. Hopefully it will last longer but the light quality is not the same IMO.

I refuse to alter my lifestyle - for the worse - just too aleviate some sort of wealth guilt or whatever physological jargon describes this hysteria. When India and China go green then the US can look into it. Until then damn the torpedoes and full steam ahead. USA-USA-USA
