Is Global Warming real?

[Umbran]

What is there agenda?

"Not have all our coastal cities under water in a century," I'd guess.

Or maybe, "Not have massive economic dislocation and famine across the world as crops fail, leading to international strife."

Those climate scientists. Always thinking of themselves.

How does the half life of DNA prevent that? The life span of an organism has nothing to do with the half life of DNA.

Because a given cell sitting at position X.Y.Z in a stationary biological entity is going to be sitting there with a glob of DNA for longer than its half life.

From the sense of the tree growing that long, obviously it didn't matter. But from the sense of there's a tree made of matter that is passing it's half life. That's interesting.

Because a given cell sitting at position X.Y.Z in a stationary biological entity is going to be sitting there with a glob of DNA for longer than its half life.

But that's not quite how it works. While the organism as a whole may live some number of years, no individual cell lives that long - so no individual molecule of DNA has to exist for that long. Each time the cell divides, there's a maintenance on the DNA, where errors or degradation can be corrected.

This, on top of how the living cell environment actively eliminates things that damage DNA, when a dead cell does not. It'd be reasonable to say that half-life number does not apply to DNA in cells that are still actively maintaining homeostasis.

It is like... typically, an abandoned house will crumble after so many years. But it won't crumble at all if someone is living in it and maintaining it.

EN World's sister-site, Circvs Maximvs, has a nice one (in red) named "curses.gif" -- but to use it here, you would need to save it to your file system, them upload it as one of your allowed files to EN World. (Merely copying and pasting doesn't work using Windows 7; I've tried.)

That kind of thing is a bit of work. I have seen such things done, but few users here bother about it.

I don't necessarily believe that the current state of climate change (and that's the term I use, not global warming) is entirely caused by human action, especially when you consider that the amount of pollution caused by volcanic eruptions are greater than the amount caused by human action each year, though I agree that human action has an effect on the situation. Climate change is inevitable and constant, to suggest that altering the activities of humans will somehow stop the climate change from occuring is bunk, IMO. No amount of government decisions, nor curbing of industrial activities will stop the climate from changing - the ice is melting globally and there's nothing we can do about it. Generally phenomena that is completely outside my control (like climate change) is something I don't worry about it. I only worry on those things that my personal actions can alter. If I can't alter it, then it doesn't matter - it's going to happen anyway, so why worry?

I've seen this a few times in this thread some people say that volcanoes release more CO2 in the air than us. It ain't true.

The real point is, short of becoming the absolute ruler of Earth and forcing everyone to stop driving cars, stop creating green house gases through industrial processes, no one can stop the progress from happening - its like trying to stop a volcano from erupting (it ain't going to happen). I still believe there's nothing that can be done, nor will be done. So I still don't worry about it.

But that isn't true, either.

Anti-pollution regulations & technological advances have reduced emissions from automobiles and industrial processes. If not for them, we'd be MUCH worse off.

Have they eliminated the threat? Clearly not. But they have bought us decades of time with which to deal with the issue.

Doing nothing is simply a recipe for creating a second Venus in our solar system...

I don't know, I'm not a scientist, and one can easily find 2 scientists that don't agree with each other on any matter. Will the legislation help, you believe that it does, and maybe it will, but I don't really buy into that. Besides we're liable to be destroyed in any number of ways (over population, meteor strike, pandemic) before Earth becomes another Venus - we're doomed anyway, but as long as that isn't during my lifetime, I'll keep it out of my thoughts.
