Well, yeah. We have a lot of desert on our planet.

[Putnam]

The main problem is the ice, I think.

[Lagslayer]

It's about liquid water and sunlight. Our planet has a lot of ice, and several areas with relatively little water. Additionally, our oceans are quite deep, so the sea floor tends to get little sunlight even a short way off the coast. High temperatures draw up more water, and therefor, more nutrients from the soil. Places with high temperatures, lots of sunlight, and plenty of water have the densest vegetation. Add all 3 together and you get rainforests, the most miserable places on earth.

Why am I babbling on about this?

[Descan]

I was trying to think of things that a exo-planet has that would affect vegetation-ability that we would be able to know about.

I.E. size of planet(maybe), and distance from the sun.

Though I don't know if we're too close to the sun, thereby heating up the equator and giving us deserts, or too far from the sun, thereby freezing water and locking it up to prevent in-land regions from getting to it.

I'm thinking it's the latter, based solely on the fact that in this context, we have no real way of knowing how much water is on those other planets. At best, we can tell how much water is in the atmosphere, and I think that's only a recent thing we can do. So without knowing how much water is in it's hydrosphere, the "higher vegetability" would be a planet that has no chance of having frozen water.

Is my thinking, at least~

*Note: Since we don't know the land-areas and water-content of most of these planets, it's totally possible for a planet to have a thin film of water on a barely-bumpy planet, or have a pangaea-like continent. One would make it so EVERY place on that planet is within a few hundred miles of water, so very few deserts, and the other would almost certainly create a massive in-land desert. These two scenarios would skew a planet that would otherwise be poor/rich in vegetation to the opposite end, simply because of geography that we can't actually see from earth.

According to this(companion calculator here), we are actually too close to the Sun. There's some atmospheric effects that keep us habitable, but we're definitely on the hot end.
This is in terms of insolation only, mind you, as the planet could have the same average temp and be much farther, as long as there were strong greenhouse effects.

You misspelled "none".

Have you actually been in a tropical rainforest? I have, and in summer, they're much cooler than the open areas.

Aren't we too far?

[Il Palazzo]

Aren't we too far?

No. As discussed in the paper, we're on the inner edge of the Goldilocks zone.

I've posted this just about everywhere else, but I may as well post it here too:
The new Cosmos series with Neil deGrasse Tyson starts within the next day. So be sure to watch it.

[10ebbor10]

The Great American wall?

[Dutchling]

As long as they're made of ice and are filled with bi-curious cons, I'd be okay with that.

[Gentlefish]

WTF? Did I miss something?

[Darvi]

Most likely referencing the A Song of of Ice and Fire books.

[Sheb]

I think Dutchling only ever read ASOIAF fanfiction.
