I am most concerned with the width of the current warm period shown on the graph as compared to the sharp peaks shown on previous warm periods. If what happened in the previous periods is what was most likely to have happened in the current warm period we should be halfway to another massive glaciation. This interglacial period has lasted around 10,000 years. The biggest change since the previous warm periods and this period is the presence of humans.
The questions is what did we do and are still doing that kept the planet warm when in previous situations the temperature reached a peak and rapidly dropped to a much lower level. If we are the reason the planet is staying warm we had better figure out what we are doing and keep doing it. It does not take much temperature drop to eliminate the grain growing regions in the Northern hemisphere. Loss of that food in a world of 10 billion people would create substantial difficulties.
Unfortunately, the food growing regions will not be in places where people are living. Our main problem with global hunger is distribution. Since we already pretty much suck at making sure everyone is fed today, when we do have enough food, imagine what is going to happen when the regions of the world where all the population is going to be concentrated (e.g. India, Africa) completely runs out of water for agriculture. Just because Canada can start growing corn (though not at the current yield as our Midwest because their soil is not as fertile) doesn't mean that this corn will ever make it to the people who need it.
These manmade-climate-change fanatics believe we should radically change our lifestyles and devote massive resources (time, money, effort) to trying to make the climate different from whatever it's going to be.
And if any of us don't want to, then the government should force us to.
But whey you ask any of them to prove such a massive project for most of humanity, will have any effect at all... well, you see what happens. They bury you in mounds of "research", but somehow never actually answer the question.
The reason such proof is always missing from their replies, is clear: They have none. Because there isn't any.
Any influence by man on Global Warming, has no factual backing whatsoever.
In truth, climates frequently change.
Sometimes the climate gets warmer.
And sometimes it gets colder.
That's been going on for as long as the planet has been orbiting the Sun. Or, as long as it's had a climate, at least.
And man has never had the slightest influence on it.
Even the leftist loons who scream about how we have to use government to change everything, go back to the stone age, etc., to prevent some unknown catastrophe, have never been able to come up with even ONE study or example that backs up their claims.
What's funny is that, when they do name some study, it invariably turns out to be nothing but a bunch of long-winded claims which, finally, refer to some other "study" for proof. And what is in that other "study"? You guessed it - more long-winded claims, and eventually a reference to yet another study. And you can guess what is in that one, too.
The leftist global-whatever loons have been insisting on impending doom, and the urgent need to give government massive powers to change every bit of our lives to "avoid" that doom, for at least 40 years by my count. Literally billions of dollars have changed hands - usually into their hands - all over the world. And they still haven't come up with one shred of proof that man has had the least bit of influence on the climate changes that happen regularly around us. Nor is there any proof that man can do anything to change it.
***40 YEARS*** of screaming, caterwauling, and doomsaying. All without the slightest proof. Just references to references to references, ad infinitum. And demands that they be given complete power over all of us, to change what they cannot change.
you do understand the difference between the three words
It's not an insult, it's just a fact - do you REALLY think you are as smart and as knowledgeable as folks who have spent - in some cases - decades studying this stuff?
Really?
REALLY??
If so, what are YOUR credentials?
Where did YOU get your degree on the subject?
Where did you train?
What papers on the subject have you had published and sujected to peer review?
What makes YOUR opinion be of ANY value whatsoever when discussing such a complicated technical subject?
The REASON there is CONSENSUS is because they examined the PROOF.
It doesn't matter whether YOU consider it "proof" - people wayyyyyy smarter than you (or anyone on this board) - people who have spent their entire professional lives pursuing science - are in 97% consensus that the results are valid.
Is there a slight chance they could be wrong - sure, but when that HUGE a margin of the people who KNOW the subject BEST are in agreement, that's a DAMN GOOD BET that the results are right. it's rare that ANY subject of scientific study has that degree of consensus.
The problem with you wingnut types is that you clearly have a distrust of ANYTHING that goes against your dogma - and rather than actually CONSIDER the DATA, you just ATTACK the MESSENGER. You did the same thing with Nate Silvers' prediction that Obama would win re-election, the same thing with those saying the stock market had turned around back in 2009, the same thing with those saying the economy is in recovery and the same thing with the BLS numbers showing that the UE rate is dropping - and you've been wrong EVERY TIME.
The fact that YOU don't LIKE the results of the DATA, doesn't make the data invalid - nor does it mean those publishing the data are lying.
Data rules, dogma drools - and the data in this case is VERY CLEAR - the climate is changing and Man is playing a major part in that.
Unfortunately, the food growing regions will not be in places where people are living. Our main problem with global hunger is distribution. Since we already pretty much suck at making sure everyone is fed today, when we do have enough food, imagine what is going to happen when the regions of the world where all the population is going to be concentrated (e.g. India, Africa) completely runs out of water for agriculture. Just because Canada can start growing corn (though not at the current yield as our Midwest because their soil is not as fertile) doesn't mean that this corn will ever make it to the people who need it.
On average, the global average temperature is practically the same. Incoming radiation is equal to outgoing radiation. Yet over millions of years, very insignificant and very minimal daily changes have sent the earth between a ball of ice and a ball of fire.
...Consider the different heat retention properties of things like water and land.
...Consider the physical differences between solid water and water vapor and it's significance to weather.
...Consider the heat retention of the various gases in the atmosphere.
...Consider the fact that the night and day temperatures vary greatly on Mercury and aren't present on Venus.
...Consider the light blocking properties of matter in the atmosphere.
...Consider the temperature inversion in the atmosphere
...Consider the average temperature of the hydrosphere.
...Consider slow moving ocean currents.
And who has been unable to refute any of it... but has proven a pretty good source of excuses and diversions.
I have, multiple times. I think you're looking for more excuses to insult people. Do you treat people like this in real life? Demanding answers but then not listening when they are provided? Do you tell people to "keep up" when they disagree with you? Do you call them "little" when they try to hold a conversation with you? If so, how does that work out for you?
Our conversation has been one sided. I've provided answers, you've just asked the same exact question over and over. And then you scream and yell if I don't reply. It's awfully...annoying to say the least. I do wish that city-data still had the block user feature but I can't seem to find it.
Found it! You have to click on user, then "user lists/ add to ignore list" I knew it was there somewhere. Good to know when you want to delete robo-copy-and-paste users from your list.
