Rise in CO2 has 'greened Planet Earth'

Rise in CO2 has 'greened Planet Earth' - BBC News

Carbon dioxide emissions from industrial society have driven a huge growth in trees and other plants.

A new study says that if the extra green leaves prompted by rising CO2 levels were laid in a carpet, it would cover twice the continental USA.

Climate sceptics argue the findings show that the extra CO2 is actually benefiting the planet.

But the researchers say the fertilisation effect diminishes over time.

They warn the positives of CO2 are likely to be outweighed by the negatives.

So they say that the positive effects get less better over time. OK. We'll just take the good and not expect it to get that much better than now but not go back to the bad old days.

Those negative effects though.. those would be the ones which show no signs of actually happening....
 
But if the earth gets greener, the governments have less control over the world's food supply.
 
Makes me wonder if the Earth's climate has a very long lived CO2 cycle, on the order a millions of years, as I recall there was a time in the Earths' history were CO2 levels were far beyond what we have today.
 
I am concerned about global warming for practical and personal reasons, not because I believe we are destroying the planet.

The planet will go on existing right up until the Sun goes nova or it is destroyed by some other cosmic catastrophe, even if every living thing on it dies off. Our planet has existed for billions of years before any life appeared, and will continue to exist after all life is expunged from it's surface.

Moreover, we know from the fossil record that life has changed many times since it first emerged on this planet and will likely continue to change until completely eradicated.

What we do will not destroy this planet. That is pretty clear.

However, what we do will have a direct effect on life as we know it and that is the concern expressed by Global Warming advocates. People who believe that we need to act on those things within our control that are clearly detrimental to the environment that maintains OUR continued existence on planet Earth.

What practical, scientific solutions are being promoted by AGW believers?

The worst case scenario, as predicted by the IPCC, is for a 4.2c rise over pre-industrial temperatures by 2100. We already have had 0.8c and have not seen the 0.3c per decade rise needed to achieve this since the graph that predicted it came out 18 years ago.

So what do you think is so bad about it all?

This is the question I have asked another on this forum 8 times so far with no answer. I see that you do not expect the earth to boil but what negative effects do you think are going to result from a small increase in temperatures?


From the link in the OP;
The scientists say several factors play a part in the plant boom, including climate change (8%), more nitrogen in the environment (9%), and shifts in land management (4%).

But the main factor, they say, is plants using extra CO2 from human society to fertilise their growth (70%).

The main change so far seems to be a huge increase in plant fertility. 70% more plants (well, leaves) now due to CO2. I think that's a good thing.
 
Makes me wonder if the Earth's climate has a very long lived CO2 cycle, on the order a millions of years, as I recall there was a time in the Earths' history were CO2 levels were far beyond what we have today.

The "cycle" is caled CO2 sequestration and yes it took millions of years for plants to lock all that carbon up. We are releasing it all back into the atmosphere in a few hundred years. What could go wrong with that, right?

The last time there was this much carbon dioxide (CO2) in the Earth's atmosphere, modern humans didn't exist. Megatoothed sharks prowled the oceans, the world's seas were up to 100 feet higher than they are today, and the global average surface temperature was up to 11°F warmer than it is now.
As we near the record for the highest CO2 concentration in human history — 400 parts per million — climate scientists worry about where we were then, and where we're rapidly headed now.

Maybe for plants...

But recall, plants were the first things to successfully populate the surface of the earth filled with CO2 from vulcanization. While THEY thrive in a CO2 rich environment, WE don't.

Also, as we grow in population we also cut back on plant life to make more room for our homes and businesses. This growth is not a problem when the human population is small. But it becomes one when we reach a critical mass where there aren't enough plants to feed us or convert the production of CO2 to oxygen needed for our respiration. Killing off plankton does not help this situation either for the atmosphere balance or the maintenance of the ocean's food chain. What then?

Think "Soylant Green is people." Or imagine the hive cities in the "Warhammer 40K" series for you science fiction fans. ;)

Increased crop yields and a greener planet. Oh the horror. :roll:

We were supposed to reach this "critical mass" of population decades ago. When is the new projection? Maybe we should adopt the Chinese, one child per family policy. :eek:

Just because critical mass has not happened yet does not mean it won't ever happen. I'm not making any projections of a specific date. I am not that arrogant.

I just recognize that if we keep acting like there is no problem and there is nothing we can or need to do...then we are setting ourselves up for failure.

Eh?? Your thinking seems all over the place.

You do understand that the room you are in has vastly higher levels of CO2 in it than the general atmosphere just because you are in it breathing. CO2 is not harmful to humans untill you get to extremely high levels that are not at all possible unless you are locked in an air-tight room for too long.

That we can now grow more food from less land is surely a good thing and set to get better. Even more food from the same land. Good thing.

So for the second time [2];

I see that you do not expect the earth to boil but what negative effects do you think are going to result from a small increase in temperatures?

The Last Time CO2 Was This High, Humans Didn't Exist | Climate Central

The CO2 sequestration cycle that you've identified is something well beyond mankind's ability to significantly influence much less control, such as what the AGW movement is claiming needs to be done and can be done.
 
What practical, scientific solutions are being promoted by AGW believers?


So far all there has been is 1960's-like babbling about wind power and varying degrees of hysterical predictions all leading to "we need more research". In another forum I read an incredible excuse: "there hasn't been development of solutions because scientists have to fight off deniers"

That's right, the people who question their god state are to blame, never mind the fact not one solution or even protection has even been presented let alone discussed.

There are studies that suggest warming may not be a bad thing. As week speak Canadian farmers on the prairies have added several days to their growing year and can now grow better strains of wheat, canola etc.
 
We are just practicing out terraforming skillz for Mars..

If you mean we can't put the genie back in the bottle that is correct. But burning and releasing all the sequestered carbon is quite with in our reach and we can certianly send Earth back to the Carboniferous age as far a CO2 goes and once it is out we are stuck with it for millions of years. We also can choose to leave the bulk of sequestered carbon in the ground where it will not effect our climate or the oceans.

Climate during the Carboniferous Period

So you don't want to have a boom in plant growth and a climate very similar to ours... OK.

Probably the greatest source of CO2 from the human race is in all the people breathing. Good luck with curbing that. :screwy:

To be blunt, we can pollute the atmosphere and water and make the planet temporarily less safe to live on....for instance the smog in many large US cities, however we do not have the destructive power to alter the planet's climate cycles. The global warming alarmists are just coocoo for cocoa puffs.

All that carbon in the ground- coal, oil, whatever, used to be in the atmosphere. It was drawn out of the air by the enormously lush growth in the Mesozoic (or whatever) Era and those plants died and underwent some magical juju that I've forgotten since elementary school and became, yes, fossil fuels. All we're doing is returning that carbon to the atmosphere so the planet can warm up again. None of which is a problem except where we have a lot invested in the status quo and stand to lose big bucks if there's any basic changes.
Me, I could do with less winter, even the pseudo-winters we get here. So long as there's no dinosaurs in the deal.

:agree: Guaranteed to totally end the discussion! :lamo: It's good to keep in mind that there are some redeeming factors in suggesting that if it's such a great idea they should be the first to apply! We really should use it more often, IMO! :thumbs:
