Climate Change Tipping Point Reached

smokestacksHuman-fueled global warming has reached a “tipping point” and will continue even if greenhouse gas emissions were halted immediately. A review of climate science also found severe climate change impacts are evident now and urgent action to minimize damage is necessary. There are many reasonable policy responses that could be implemented now. Every day we wait, the greater the momentum behind abrupt, runaway climate change. 76% of Americans desire leadership to reduce pollution linked to global warming.

    Based on the reports in books,web sites and news outlets,I am of the opinion that our best bet is to adapt to the inevitable,we cannot stop it now.
    We are a species like other species with powerful biological urges especially to procreate.
    Our best bet would be an orderly retreat by deliberately reducing our population,i.e. five couples have two children between them rather than ten,and a halt to all economic growth,that is contracting economies and populations all round the world.
    We need to do this anyway as the world is fast running out of oil,on that basis alone we need to completely
    transform the way we do things.
    By the time climate change really affects us we should be trimmed down to at most 2 billion people living in localised economies with minimal carbon emissions.In that position hopefully we can ride out what ever comes our way.If I were in a position to have children I wouldn't considering these two catastrophes on the horizen:Peak Oil and non linear Climate Change.
    Also if we use up the rest of the oil we will make climate change even worse we might be reduced as Lovelock thinks will happen to a few hundred thousand eking out an existence in parts of the world still inhabitable.
    I agree with the ecologist point of view:we have increased to plague proportions such that the biosphere,Gaia,cannot maintain its stability due to our numbers and actions.Therefore without malice our numbers will be reduced due to this instability as the planet progressively becomes less and less able to support us.
    I'd like to say that none of this thought is original to me this is what I have read since the early nineties.Scientists have been warning us for the last twenty years yet we have gone the opposite way to safety by more and more growth and more and more people!
    We have done what other species have done and overshot our environment and the bills are coming due for payment.
    I like people,not a misanthrope,I think we have just fallen,as ronald wright says,into a progress trap because we aren't as intelligent as we like to think: we still have the primitive make up of our hunter gatherer forebears,we can be forgiven: for we know not whatwe do or can help ourselves,Jesus was of the same opinion :we are doing to the Biosphere what was done to him:crucifying it an the cross of greed and insatiable appetite for more and more.
    Our religions,economics and education system have treated the biosphere as not really part of us its something we use for gain and as a dump for all our wastes climate change is happening because we have used the atmosphere a life giving ocean of air as an emission sewer.When we pray to god the world is just a half way house to our future heaven.In economics there is no recognition of the vtal services provided by the biosphere.
    As Kurt Vonnegut has said among others Prometheus taught fire,combustion,to man and was punished by the gods:That's where all the trouble started we went on to burn wood then coal then gas and oil and their huge trapped energies enabled us to expand our numbers and with machines to devastate the world.

    okay since gov. isn't going to do anything about this. What can I do for myself?

    Australia, is being hit with a cat 5 cyclone, as i post this. Cat 5's are becoming the norm, not the exception. We are heading for a disaster, of epoch proportions. While the U.S., is twildling their thumb's. What's it going to take, a half a dozen Katrina's to wake us up. Yes, we have reached the tipping point, we were warned. Now, we are going to have to pay the price, for ignorance. GOD HELP US! I just read, the Senate, shot down a key global warming initiative, and made it voluntary instead. These people dont get it!

    The shortage of potable water will devastate us before the full impact of climate change hits. Clean drinking water has become a serious health issue related to the increase in air, earth and water pollution. A quality life is impossible for man and beast without water.

    In answer to the question: What can I do? Here are a few suggestions:
    1. Choose your consumer goods wisely – buy local, buy a hybrid car, buy less, buy efficient home appliances, build with green building techniques, reuse your shopping bags, etc.
    2. Use less energy – turn off lights, wash dishes by hand, turn your furnance down, drive less, take the bus, ride a bicycle.
    3. Lobby your suppliers – ask them for ecological products, local products, if they do not stock them.
    4. Lobby your government – demand better urban planning, energy policy, etc.
    5. Vote for people who care about climate change and have a plan.
    6. Educate yourself and those around you – read articles on the internet, books, go to community meetings and lectures.
    7. Do EVERYTHING LITTLE THING YOU CAN IN YOUR BACKYARD – walk the talk, small things start major movements.
    8. Stay positive – what's alternative?

    The above suggestions are well and good, but the only thing that matters at this point is mitigation of GW effects. Here's why:
    To stabilize our CO2 level in the atmosphere will require cut of as much as 90% in per capita emissions. This means reducing our individual carbon footprints to a ton of CO2 or less. Understand what that means…
    1 kwh of electricity makes about a pound of CO2 currently (in the US). So that means 2000 kwh/year of electricity, and no other fossil fuel use whatsoever. Te average household in the US uses about 600 kwh/month. Good luck…
    Driving a small car (40+ mpg) makes about 1 pound every 5 miles. So this translates into 10,000 miles/year. No electricity or other fossil fuel use. Your average American drives 12,000 miles per year in a vehicle that gets half or less of that mileage. Good luck…
    Heat. Natural gas makes about 4 pounds per therm of CO2. The average household uses about 60 therms/month of natural gas, and about 150 in the winter months. That means you can heat your house for about 2 months, and cook for a couple more. No electricity. No car. Nothing else fossil fuel powered.
    Add all these up and you see why we will never cut back enough to stop global warming from spiralling out of control. Following the above posters suggestions will help delay the tipping point a few years (months?) but will not stop it. Not even close.
    Build your water catchments, your drought resistant crops, put your house on stilts, move away from the coasts, cause it's coming. And given our population and it's desires, there is no way to stop it.
    And don't have kids…

    On a Lighter Note
    Have found a great poem by Rudyard Kipling illustrating the immense power of machines
    powered by fossil fuels.He lived from (1865-1936)and was awarded the Nobel Prize for Literature in 1907.This poem was prescient as to our current predicament.Although of course we also now live in the electronic digital age our machines still wreak havoc.
    (Modern Machinery)
    We were taken from the ore-bed and the mine,We were melted in the furnace and the pit-We were cast and wrought and hammered to design,
    We were cut and filed and tooled and gauged to fit.
    Some water,coal,and oil is all we ask,
    And a thousandth of an inch to give us play:
    And now,if you will set us to our task,
    We will serve you four and twenty hours a day!
    We can pull and haul and push and lift and drive,
    We can print and plough and weave and heat and light,
    We can run and race and swim and fly and dive,
    We can see and hear and count and read and write!
    Would you call a friend from half across the world?
    If you'll let us have his name and town and state,
    You shall see and hear your crackling question hurled
    Across the arch of heaven while you wait.
    Has he answered? Does he need you at his side?
    You can start this very evening if you choose,
    And take the Western Ocean in the stride
    Of seventy thousand horses and some screws!
    The boat-express is waiting your command!
    You will find the Mauretania at the quay,
    Till her captain turns the lever 'neath his hand,
    And the monstrous nine-decked city goes to sea.
    Do you wish to make the mountains bare their head
    And lay their new-cut forests at your feet?
    Do you want to turn a river in its bed,
    Or plant a barren wilderness with wheat?
    Shall we pipe aloft and bring you water down
    From the never failing cisterns of the snows,
    To work the mills and tramways in your town,
    And irrigate your orchards as it flows?
    It is easy! Give us dynamite and drills!
    Watch the iron-shouldered rocks lie down and quake,
    As the thirsty desert-level floods and fills,
    And the valley we have dammed becomes a lake.
    But remember,please,the Law by which we live ,
    We are not built to comprehend a lie,
    We can neither love nor pity nor forgive.
    If you make a slip in handling us you die!
    We are greater than the Peoples or the Kings-
    Be humble,as you crawl beneath our rods!-
    Our touch can alter all created things,
    We are everything on earth-except the Gods!
    Though our smoke may hide the Heavens from your eyes,
    It will vanish and the stars will shine again,
    Because,for all our power and weight and size,
    We are nothing more than children of your brain!
    Kipling understood fully the Promethian power of the Industrial Revolution. Man,because of fossil fuels and their immense trapped energies coupled with machines to exploit these energies quite literally had attained almost god like powers over his situation.
