Is climate a problem?
If living on Mars, will climate be a problem?
I think a priority, would be to stop the global dust storms on Mars.
And it might be pretty easy to do this.
Climate is a problem, but problems can be solved. Hysteria is harder to solve.
Pretty much.
I recommend breathing into a paper bag.
Works fine for self help, not so much for non-cooperative others.
What is the “problem” with “climate”?
Is the current climate optimum, and if not, what is wrong with it. What should the optimum be, and when was the last time that optimum was achieved? Since “warming” is usually described as bad, shall we assume that it should be cooler? By how much, and does that apply everywhere?Since there have been times in the immediate geologic past when the Midwest and Canada were under a kilometer or more of ice, is the goal going to be to keep that under 100 meters, or confine it to Canada this time?
And why wouldn’t a place like Canada, or Siberia, or Greenland, or Iceland, want to be warmed up just a little?
Indeed, it is worse than that – according to models, places that are currently warm will not warm that much. Most of the warming happens where is is sub-optimally cold right now. So the most likely scenario is that the world is a better place after the warming.
Well Raoul, recently in SE Texas; we went from early February days starting in the low 40s then rising to maybe the 60s. Today, the day started in the 60s and will go up to the 80s. That caused a problem because I had to put my coat in the closet rather than wearing it outside. Coat is put away and problem solved.
I might have to go out for a walk this afternoon in the sunshine. Wish me luck.
Any policy to address climate with the intent of changing it, or halting its changes, is doomed to failure because the climate will always be changing. A sensible approach would be to recognize that the future is uncertain and that nature could throw anything at us, just as it always has.
A wealthy and advanced society would mitigate the risks of an uncertain future by making their society more robust and agile and not penalize the populace for the crime of existing.
–SPACE LAW UPDATE: The 1st private moon landing just happened. Is it time for lunar law? “The thing about space is there is very little law.” I see that as less a bug than a feature.

Has to be some laws. But if have laws you need policing and justice system. You could have rules, like if have satellite which is not controllable in region [like low Earth orbit] or it’s space junk, you lose ownership of it {someone can harvest or take your space junk}. And it seems there needs to speed limits if a trajectory gets close to something like L-5 colony and similar idea, if can’t control it, you lose ownership, or your life if on it, if on trajectory going too fast near it.
And it seems policing is just know where every object is, and particularly near places people are living.
But it seems problem of crime in space, is lack of any ability to hide in open space.
But what about storing nuclear waste in your backyard on the Moon? Would it be better to a communal crater
to put radioactive waste into?
What happens to your Lunar claim when the lander signals back, “I’ve fallen, and I can’t get up!”
I tell people to look up the Azolla Event. Our current climate is the result of an ecological catastrophe.
Rather than small green floating plant, I think it was from the dinosaur killing impactor.
In terms of heat created from the impactor, it was far too small to boil our oceans. It would need to be at least ten times it’s diameter for that to happen.
But it was big enough to have large geological effects.
And the issue of arctic being mostly being freshwater lake was factor.
In our current climate we have vast amount of cold water flowing out of arctic cooling bottom water of all the oceans, but you need saltwater in arctic, for this to happen.
A greenhouse global climate needs the ocean average temperature to warmer than 10 C, and our icehouse global climate has average ocean temperature of about 3.5 C.
And it’s this cold, due to antarctic and arctic cold water falling into it.
And whenever our entire ocean warms up to 4 C or more, you get interglacial periods, though most of the time we are not in an interglacial period. And also the interglacial periods are related to Milankovitch cycles- as is commonly accepted.
All the available evidence suggests you’re wrong. Climatological events post Cretaceous lead up to the PETM. The climate crashed after the Azolla event, when 80% or more of C02 was removed from the atmosphere and deposited on the floor of the Arctic Ocean. We’ve been living in an unstable icehouse since then.
On the Azolla event, it’s worth noting that there’s a fair bit of evidence for it.
This is a bit verbose, but it establishes some of the basic facts of the PETM (Paleocene-Eocene Thermal Maximum). There’s fossils of reptiles at high latitudes indicating an unusually warm period. There’s a 6 meter thick Azolla fossil layer in an ocean core (see fig. 3) demonstrating that the plant was indeed packing away significant carbon at that location (and Azolla too favors warm conditions). While not discussed in the above paper I believe Azolla fossil layers are commonly seen in cores through the Arctic Ocean basin indicating that the amount of CO2 drawdown would have global effect.
Finally, the study was about an experiment to determine growth rates under different CO2 concentrations. Azolla showed massive increase in growth rate. I gather constrained by the usual secondary nutrients like sulfur, phosphorus, and iron. It has efficient nitrogen fixing so that isn’t a constraint (and leads to its astounding growth capability).
