Latest sea ice - updated daily.     Latest CO2 - updated monthly.   CH4.    El Niño.
A little rise in temperature as well as a rise in greenhouse gases will push global warming further,
amplified by not well understood feedback loops.
In addition to water vapor, CO2 is the dominating greenhouse gas.
However the concentration of CO2, shown on the graph below, goes in the wrong direction.

Man made activities during the last 100 years is correlated to the sudden rise in CO2 concentration.
Data from ice cores shows "more normal" fluctuations 2000 years back - but what happens right now
is alarming - as it elevate the global temperature shown at the bottom of the page.
The safe level may be 350 ppm CO2, but who is responsible for setting a limit.

  Where should we aim to prevent dangerous climate change?
  To make the decision "not to act" will have severe consequences.
  Just to say that the climate has always been changing is to accept the consequences.

  Methane Hydrates, at present trapped underground, makes things even worse and so do more
  water vapor, as the concentration of methane and water vapor goes up with rising temperature. 
  CO2 produced by soil bacteria and forest fires goes up as well.
  This "positive feedback loop" can suddenly make things go very fast.
  A "Runaway Climate Change" situation is hopeful not yet the case

                    CO2 may have to stay in the atmospheric for thousands of years.
New data shows Warmer oceans. It decreases the take-up of CO2, and  Deforestation makes things worse.
As more than 90% of global warming ends up in the oceans, the rise of sea temperature gives a clear status.
It is also a proof of global warming.  Most of the energy involved per year is calculated and shown here.

Be prepared for severe flooding and climatic change or take action to cut CO2 emission.

More extreme weather can be expected. e.g.
  Longer lasting and more intense heat waves, wildfires, long intense rain showers,
  stronger hurricanes, change in vegetation and more spread of pandemic disease. 

Phytoplankton, a source of Ocean Life and photosynthesis at sea, is already declining.
Plankton is the major CO2 sink as huge as the forests and green vegetation at land.
It also produce half of the oxygen on earth and the volatile organic sulfur gas DMS,
a key element to increase cloud cover.

Military advisers makes recommendations as mass migration, war and conflicts may follow.

The Antarctic ice sheet is next.  -   Rivers emerge beneath the ice. 
Report by a short Video and a new map.
The Ross Ice Shelf, a massive piece of ice the size of France, can collapse without warning.
The much smaller Ice Shelf, Larsen B, disintegrated in 2002.
Meltwater has the last 20 000 years changed the sea level by more than 100 m.
2008: Antarctic glaciers melting more quickly.

A lot of uncertainty remains. 
- Is a reduction of CO2  - wherever possible - enough to stop the rise in temperature ?
- Some scientist says "it is not just us" - maybe it is solar activity.  If so even more
      has to be done to limit the damage created by both man and e.g. the sun.
      Please checkout the recorded sunspot number by yourself - it has been unusual low during 2008 and
      the beginning of 2009 but it is primary a 11 year cycle so it comes up again during the next few years.
      The present deep sunspot minimum and La Nina would normally give a period of cooling.
- The fact is instead Global Dimming.  BBC part1,  part2,  part3,  part4. part5.
- It won't help either to blame water vapor, if we can't remove it.
- To invent climate myths is not ethical - there is too much at stake.  We have
   to investigate the facts very fast to find the right solutions.
- Whatever the causes, we can not afford the temperature to get out of control.
- What is the cost of doing too little too late ?

CO2 cuts, wherever possible, is probably too little to stop global warming,
but CO2 can be pumped under the sea flour in liquid form ²⁾
Methane gas should be collected and used as fuel instead of leaking to the atmosphere.

^{2008: Wilkins Ice Shelf in Antarctic break-up.}

We are dealing with a balance in the earths  carbon cycle and energy budget.
By tipping the balance, temperature are set to rise. Higher temperature will tip the balance even more.
In artic regions with methane trapped under permafrost, temperature goes up faster than shown below.

The temperature will accelerate further up³⁾ for some time until we reduce the concentration of CO2 in the atmosphere⁴⁾ to a level
that brings the energy budget back into balance.
As less CO2 will be absorbed by the ocean due to higher temperature and saturation effects, equilibrium will require very low CO2 emission.

To delay a major cut in CO2 is to allow the temperature to jump and methane to be released - far worse than CO2.
Fatal delay has already been added by Global Dimming, masking Global Warming by air pollution.
The reduction of sunlight in some areas is up to 25% and the main source is Asia's brown cloud.

It will rise the temperature further and trigger CO2 to flush out of the deep ocean through natural ocean currents and CH4 to flush out of the seabed.
Passing a point of no return, temperature will lead and concentrations of CO2 and CH4 will increase further.
A "thermal runaway" situation like the prehistoric global warming episode, called the Paleocene-Eocene thermal maximum, or PETM.

Planet earth survives oscillations between ice ages and periods of extreme warming with a plummeting oxygen level.   However most species do not.

Man has to fight the very powerful forces of nature before passing the point of no return.
The warming has to be stopped using all means known today and additional new
means such as e.g. a reflective non polluting stuff in the atmosphere.
However tests should be monitored by the press in order to share
the expensive research results.
The massive ongoing tests seen in the sky behind some airplanes
shows huge operations but the research results are so far a secret ⁵⁾.

Years from now we hopeful find more means to stop global warming best described by
the rise in Ocean Heat Content.
The major dips in the curve are correlated with volcanic eruptions.
Things are probably much more complicated than known today, but CO2 is an important
factor that can be changed by us.  Other factors may be beyond our reach.

The sun offer us all the energy we need.  Nuclear and wind power is a supplement.
Better batteries and fuel cells are being developed.  However we are short of time.

Some future control of water vapor and clouds could be very helpful and so would bacteria
in converting CO2 into something more useful.  Until then CO2 can be stored underground,
CO2 can be reduced and new CO2 efficient equipment can be used.

A little more "borrowed time" may be available from geoengineering La Nina,
by forcing cold deep sea water up if we have to gamble.
New CO2 free energy sources could be "the solution" - if such technology
is "low risk" and has "a clean" production process.

We are the last generation able to stop a runaway climate change as Tipping Points are passed right now.
 "The point of no return" means no way back even if all economic and all military resources are used.
A 100% CO2 cut will be far too little to stop the forces of nature.
"Runaway" means that the temperature can not stop when we pass year 2050 or 2100 - first stop is "hot house".

If we fail during the next few decades, the setback can be 100 000 years or 1 million years.
During a few decades, we can loose modern technology and the rate of change can be so fast that there is not enough time
to adapt to old technology even stone age technology.
The huge amount of methane hydrate collected since the last major event 55 million years ago can easily set the species of
planet earth further back.
A runaway warming probably stops at a hot equilibrium stage before planet earth heats up like Venus, but we do not know.
Venus has demonstrated what happens when too much greenhouse gas is stored in the atmosphere.

Homo Sapiens: "Endangered Species" or "Invasive Species"  ?

The End

¹⁾  Move the map with mouse + left click engaged.  Adjust sea level and select Hybrid to combine a satellite map with a road map.
    Zoom by using the slider in the left upper corner to show future flooding in your local area.

²⁾  Realize that one kilo fossil fuel mostly consists of carbon atoms - nearly one kilo carbon atoms.
    To form CO2, two oxygen atoms, coming from the air, are added and they are a little heavier than carbon.
    It adds up to extract around 3 kilo liquid to pump underground. Large consumers of fossil fuel should do that right now in full scale
    despite the cost.  However cutting CO2 is cheaper if possible, but it is not enough.

³⁾ Temperature and sea level will go up for decades even if all emissions from fossil fuel were stopped overnight - a 100% CO2 cut. 
    Maybe such an "emergency break" will work after being active each day for a few decades, but we can not be sure as the reduction
    we already made to natural carbon sinks has to be accounted for - se the carbon cycle and energy budget.
    A  backup plan "plan B" could be to extract more CO2 from the air than emitted and pump it underground - a cut of more than 100%
    Low risk 4th generation nuclear power plants burning old nuclear waste could be put into production.
    Collecting leaking methane gas could also be very helpful - oil companies already have the natural gas distribution network.
    Less meat from land animals, especially cows combined with population control.
    White paint on rooftops, cars and roads would reflect some sunlight.
    The good thing is that a small fraction of the sunlight available can cover our need for electricity and heat.

⁴⁾ The spike in CO2 concentration were obtained in less than 100 years, but  the conclusion by David Archer is that the emitted CO2
    will stay in the air longer than previously thought.  His research shows that the CO2 lifetime in the air is around 300 years
    but with a long tail, as the last 25% will take thousands of years to remove.     
    To stop the temperature in time will be difficult as we are late and most humans do not understand how a little rise in
    temperature will speedup a further rise in temperature and might trigger a flip from 10 000 years of stable climate conditions
    to a hot "greenhouse earth" -  not a healthy place for humans especially if hydrogen sulfide is released.

⁵⁾ If the aerosols (not ordinary "contrails" or "steam clouds" after jet engines but huge metallic dust clouds staying for hours) are
    designed to bring the temperature down,  we ought to se results right now.   Even without an "artificial sunshield" the global temperature
    should go down for a few years based on the cold water upwelling in the pacific (La Nina) and based on a a low number of sunspots (zero).
    Warm upwelling water (El Nino) will be back a few years from now.  The number of sunspots is now to rise following a 11 year cycle.
    What will happened if we get a combination of warm El Nino, high number of sunspots and low dust/pollution in the air ?
    Carbon sinks are  destroyed faster than ever.  The concentration of greenhouse gases ( click on the map to select e.g. Greenland and
    Antarctica for the major gases CO2, CH4 and N2O ) are now passing very critical safety levels.
    Another application of aerosols could be to reduce cosmic radiation and UV light in case of a "superwave" from e.g. the galactic center.
