re: are there still people who still believe the earth is warming and man caused it?

We know that we are adding to the amount of CO2 in the atmosphere, and numerous experiments and calculations indicate that CO2 contributes to global heat retention.

---

Plants also create CO2 correct? We have more trees in the US than we did 100 years ago. It is possible that conservation might be responsible for the increase in CO2 levels?

In the United States, which contains 8 percent of the world's forests, there are more trees than there were 100 years ago. According to the Food and Agriculture Organization (FAO), "Forest growth nationally has exceeded harvest since the 1940s. By 1997, forest growth exceeded harvest by 42 percent and the volume of forest growth was 380 percent greater than it had been in 1920." The greatest gains have been seen on the East Coast (with average volumes of wood per acre almost doubling since the '50s) which was the area most heavily logged by European settlers beginning in the 1600s, soon after their arrival.





This is great news for those who care about the environment because trees store CO2, produce oxygen — which is necessary for all life on Earth — remove toxins from the air, and create habitat for animals, insects and more basic forms of life. Well-managed forest plantations like those overseen by the Forest Stewardship Council also furnish us with wood, a renewable material that can be used for building, furniture, paper products and more, and all of which are biodegradable at the end of their lifecycle

But CO2 is absolutely essential to life, it's neither toxic nor a pollutant under normal circumstances.

Yeah it's amazing just how many people don't seem to realize there would be no life on Earth without CO2.

Not so much - "CO2" isn't really created or destroyed - it's just a carbon atom attached to an oxygen molecule. What happens is that, generally, animals breathe in air and use, primarily, the O2 molecules in the blood stream. Exhalation usually produces a higher concentration of CO2 gas (the waste byproduct of carbohydrate metabolism) than was there before, which is this attachment of carbon to the O2 molecules in the bloodstream. Conversely, plants "take in" (breathe) air and strip that carbon atom off and ultimately produce a waste product of H2O. The byproduct of this is that plants generally increase concentrations of O2 and decrease CO2, all other things being equal.

The good news in all of this is that plants like CO2 and higher concentrations should spur plant growth.

Look up "little ice age."

I have, many times.

Also, since you seem to know so much about it, maybe YOU can tell me what the Earth's global temperature is SUPPOSED to be.

---

It's not SUPPOSED to be any particular temperature, and I have no doubt that the earth will survive and recover from whatever we do to it. The only question is how long that will take, and how hard it will be for life on earth.

quote:

---

You see, the paleoclimatic record reflects that the Earth's been a shitload warmer that it is right now (or even where the most dire AGW/CC prediction models claim), as well as a shitload cooler (which is why we don't have a mile+ ice sheet on top of Chicago right now) - ALL of this without a single SUV or coal burning power plant.

---

But, you see, it took 100,000 years to go from "a shitload cooler" to "a shitload warmer", and we have no record of what may happen if such a change happens 100 times faster, OR if cooling takes 100 times longer.

quote:

---

In fact, the temperature variances show that the northern hemisphere was substantially warmer than it is now (or is projected to be in most AGW/CC models) within the last 1000 years (Medieval Climate Optimum), which is why Greenland was called that, and why you used to be able to grow wine grapes in Britain.

---

Temperatures in the northern hemisphere were probably close to what they are today, with regional spots that were warmer. Globally, temperatures were lower than today. And Greenland was named that because it needed an attractive name. Greenland during the MWP was very similar to today's Greenland.

quote:

---

So, again, what is the "global" temperature SUPPOSED to be? Because it seems THAT is the question that MUST be answered before we start wringing our hands.

---

Again, there is no "right" temperature, but the fact that we don't know what might happen if temperatures continue to rise at an accelerated rate is exactly the reason why we ARE wringing our hands.

which is why Greenland was called that

lol, no

quote:

---

One Viking in particular, Erik the Red was very good at raiding and pillaging. Although history is somewhat sketchy, it is believed that he discovered Greenland after being sent away from Iceland in exile. This was rumored to have been his punishment for committing murder. He was able to settle in Greenland and survive there for several years. Finally, his exile was ended and he found that he wanted to settle the island more fully. For that, he needed to convince others to come with him. Erik the Red is believed to have lived from circa 950 to 1003CE.

Of course, when you tell someone that they will be travelling with you to a place that is barren, cold and inhospitable you may have trouble convincing even a Viking to come with you. So instead, Erik (according to popular legend) called the island Greenland and instead painted the island as being a wonderful place to settle

What are you disputing? Are you saying that the world is adding trees faster than we are cutting them down today? That might be true, but I doubt it.

Surely you aren't suggesting that the world has more trees than it had 50 or 100 years ago.

Because human beings are part of nature. Just as larks, wrens, chaffinches, jaguars, wolves, dromedaries, badgers and otters.

So, because humans are part of nature, anything we do is "natural".

Except for when a man fricks another man, then that is "unnatural".

Just making sure I get my Poli-board facts straight.
