Couldn't Stop Laughing

Agreed. I think we might have more pressing problems than the average temperature being a few degrees higher at the end of the century!

a few degrees can be devastating for your great-grand children.

By the time the ocean rises, the seashore will be a solid line of casinos. Just lob some plaster between them and we got it beat!

Okay how exactly being even if 20+ F was added to every single day of the year very few locations on this planet would still have temperatures above what is the limits of what anyone presently deals with.

Where I live that would make the hottest days of the year around 120 - 125 F which by my wife's Turkish summer standards is a normal day there.

20+ degrees F. Your only thinking of yourself. What about other species or plants. They can't adapted. And at 20 degree + change, our food supply diversity diminish to a point of not being sustaining.

Perhaps but with a substantial increase in temperature a huge volume of presently unusable and near uninhabitable land will become highly productive and far more favorable to live in.

As far as I understand it the present temperature changes that are being used to support planet wide warming trends are not coming from hot areas getting substantially hotter but instead large areas of moderate to cool climate gaining a few degrees during their normal cold seasons which has little to no major effects on ability to support plant and animal life other than having at best longer summer growing seasons or less extreme winter lows like what I am seeing in my region.

Living where I do, I could debate that. People in California might too.

That's largely my point. Just because it sucks where you live doesn't mean it's like that everywhere else.

I have no interest in going back to a drought just so California can end theirs and I have a strong suspicion that a lot of people who do live where life has gotten better feel similar as well.

Maybe but I doubt that, And where is that land? How far is it above sea level? And what is the geology of that land. You have to realize, it may not work out the way you think. What was once productive land and now desert, does not mean it will revert back to productive land again. It does not happen in 100 years. What will happen is the over 6 billion on this planet will be reduced to about 3-4 billion.

Local favorite is Canada on the North American Continent and the majority of it's plenty high enough above sea level. Next would be the similar latitudes of Europe and Asia.

Basically anywhere that is presently seen as permafrost or near permafrost regions that are more than 400 feet above present sea level are prime candidates to become new farm land no matter how much polar ice melts.

If it really gets hot Antarctica is a huge untapped presently frozen land resource as well.

It's not that the temperature will be a few degrees higher. It is all that comes with it. Hotter heat waves like the one that devastated Russia in 2003, and 70,000 people died from crop failures and fires. More extreme weather of all kinds, including droughts like the one in California and snow storms like the ones on the East Coast. Storm surges during more powerful storms, like the one that flooded Manhattan.

It's happening now, not just at the end of the century.

If the heat causes enough melting of ice in Greenland, or causes too much evaporation in the Mediterranean making its water saltier and heavier, the North Atlantic thermohaline currents could shut down, leading to massive cold weather in Northern Europe and North America. Presto, an Ice Age just like the last one, caused not by the normal cycles, but by the loss of the heat that the Gulf Current carries North. Those currents did falter briefly in recent years, but resumed again. But maybe if we try hard enough, we can get enough CO2 into the atmosphere to make them stop.

And now it appears that the glaciers in Antarctica are being melted far faster than scientists had believed, by warm water from below, removing the blocks that had slowed their speed in the past, and making it likely that there could be a 10 foot rise in the ocean level by the end of the century. It is not that in 85 years there will be a sudden rise of 10 feet, but maybe 3 feet in 30 years, 3 more in the next 30, etc. Currently we are measuring the ocean rise in millimeters per year. If that happens those glaciers alone would make it rise closer to an inch per year, and the Greenland glaciers are also melting faster than expected.

I've found it is bad for my health to participate in discussions about this, so I probably will only respond to actual technical comments.

You should join Climate Change Threads Anonymous and get some help for this.

With help, you can beat this.

It took a long to convince people that the earth was actually not flat.

It will take a long time to convince people that they can accept something other than what they have been told by big business and its political lackies.

Whenever I feel threatened by Climate Change relapse, I call a friend who comes over and drinks with me till the anxiety goes away.

trust me, its flat

respond to 18 years of unchanged sat data

Slogans in the hands of politicians. "Don't ask, don't tell."

Yes, but vigilance is always needed. If the oceans rise too fast the Coast Guard's boats may sink. That's where the water will rise, along the coast, right?

So you don't consider this an immediate threat?

..."the levels of carbon dioxide in the atmosphere are now higher than they have been in 800,000 years. The planet is getting warmer. Fourteen of the 15 hottest years on record have been in the past 15 years. Last year was the planet's warmest year ever recorded."

and how does this impact our Coast Guard??

You might just as well ask how does it impact all of us...This is a commencement speech, generally you talk about what the new graduates will face in their future....Global warming is the largest threat facing everybody...and I think it is important for young graduates to be aware of what's on the horizon that they will have to face in their roles as protectors and custodians of the coasts and waterways....The President is the commander and chief of the armed forces, including the Coast Guard, it is his duty to keep them informed of impending threats.....Whatever role they may be called upon to perform in the future, certainly the effects of Global Warming will be among them...

BALONY

Just checked the Coast Guard's "Local Notices for Mariners" latest weekly issues for District #5, Mid-Atlantic, and #11, mostly California, and they mention the reason for the interest in global warming. They are designing several new cutters for building within the next few years. If all that ice melts and rises the water will be deeper. Water gets deeper and they need longer anchor chains for anchors. This project, code "DEEP SH$T, is being funded by the ACFoA, the Anchor Chain Fabricators of America, with "private" funds so don't be surprised if several congressmen come back with tans and big gift boxes from the investigation and familiarization trips to Bermuda. Also very bad hangovers. The answer is so simple!

Good Luck, Old Salt

the water might get deeper...........I'll have to factor that in my thinking

I'm surprised but still sceptic, to say the least. Just above a century ago we had not any kind of environmental control and basically all the industry was powered by burning all kinds of fuels. Chemicals? Aw, come on, we used some of them as medicines !.

But now that you can't even smoke but in your house (if you're allowed), and with all this green bigotry and prudery, it happens that we are killing our planet.

No one seems to be aware that climate change is inevitable, there's always an ice age on-going (or coming).

Total B. S. and hype!! Follow the money.

The money leads to purchased politicians, lobbyists and lawyers who are all paid to lie about what fossil fuels are/have done to the environment. And what they will continue to do.

The money's in mining/pumping/extracting fossil fuels out of the ground and burning them.

The Earth is not flat, regardless of what you may have been told.

California alone pumps 2,200 tons of hydrocarbons into the air every DAY. That's where the money is.

I prefer to be the anti military type of person.

"I do less all day than most people do by 9 AM."

Yes, you have tirelessly climbed into the abyss of laziness and have finally, triumphantly reached the bottom.

Well someone has to go down and set the marker so that other can know how far down 'down' is.

As far as climbing heck no. I just leaned forward and let gravity do the rest and to be honest if it wasn't for that damned wind resistance I would have gotten here a lot sooner!

Well,

That won't be me. I'm happily mired in mediocrity.

Lost in the crowd.

Never had my 15 minutes of fame.

You've managed to do OK on your own so far.

<As to temperature, I can tell you that if it were 20°F hotter here, we'd all roast.>

-increased risk of natural disasters resulting in humanitarian crises, with the potential to increase refugee flows and worsen conflicts over food and water.

-aggravating conditions such as poverty, political instability and social tensions that can lead to terrorist activity and other violence.

-new threats to the U.S. economy from rising oceans that threaten thousands of miles of highways, roads, railways and energy facilities.

-new challenges for military bases and training areas from seas, drought and other conditions.

"Around Norfolk, high tides and storms increasingly flood parts of our Navy base and an air base," Obama said of military facilities in Virginia. "In Alaska, thawing permafrost is damaging military facilities. Out West, deeper droughts and longer wildfires could threaten training areas our troops depend on."

Preparing for and adapting to climate change won't be enough, he said. "The only way the world is going to prevent the worst effects of climate change is to slow down the warming of the planet."
