The real question is why haven't you availed yourself of it .

Btw just so you know the data is on a 2 hour lag time .

The areas with high are those spewing out CO2 from fossil fuels.

And those of forcings are exactly what?

Getting back to ocean acidification:

Alterations to seabed raise fears for future

Normally the deep sea bottom is a chalky white. It's composed, to a large extent, of the mineral calcite (CaCO3) formed from the skeletons and shells of many planktonic organisms and corals. The seafloor plays a crucial role in controlling the degree of ocean acidification. The dissolution of calcite neutralizes the acidity of the CO2, and in the process prevents seawater from becoming too acidic. But these days, at least in certain hotspots such as the Northern Atlantic and the southern Oceans, the ocean's chalky bed is becoming more of a murky brown. As a result of human activities the level of CO2 in the water is so high, and the water is so acidic, that the calcite is simply being dissolved.

The McGill-led research team who published their results this week in a study in PNAS believe that what they are seeing today is only a foretaste of the way that the ocean floor will most likely be affected in future.

"Because it takes decades or even centuries for CO2 to drop down to the bottom of the ocean, almost all the CO2 created through human activity is still at the surface. But in the future, it will invade the deep-ocean, spread above the ocean floor and cause even more calcite particles at the seafloor to dissolve," says lead author Olivier Sulpis who is working on his PhD in McGill's Dept. of Earth and Planetary Sciences. "The rate at which CO2 is currently being emitted into the atmosphere is exceptionally high in Earth's history, faster than at any period since at least the extinction of the dinosaurs. And at a much faster rate than the natural mechanisms in the ocean can deal with, so it raises worries about the levels of ocean acidification in future."...

Antarctic sea ice below its normal levels.

really you keep believing that .
If that is the case then explain why the majority of the southern half of Africa is at least 420 up to 450 ppm so Africa is burning more fossil fuels than China or the U.S. ?

Did you look at the locations I posted ? ( it is easy just plug the coordinates into just about any mapping program )

Take some time to refresh your memory a bit .
It's not my issue I know you will never believe the truth .

sorry but the Danes show things a bit differently.

CO2 values fluctuate seasonally. They go down in the growing season when plants are building cellulose from CO2 taken from the air. In winter, when plants are not growing, the CO2 levels rise. It's winter in the southern hemisphere, so values there are now higher than they are in their summer.

Also, because there is more land mass and more vegetation in the northern hemisphere, the seasonal variation of the northern hemisphere dominates that of the southern hemisphere. In other words, the opposite variations of the two hemispheres do not cancel each other out.

Are you on crack? On both charts, the current line shows about 16.5 millions of square km.

jack specifically stated it was due to the burning of fossil fuels .
Stay on point . Showing the facts that there is seasonal variation is 1) counter to your its all mans fault mantra . 2 ) the majority of the region I showed as being well over the 420 mark is in the tropics so the seasonal vegetation signal is in fact minimal to non existent .

16.73 to be exact and the sea ice this year is by the Danes data is well within the normal variance over the longer term .
Btw no I'm not on any mind altering substances .
But thanks for asking about my welfare.

Absolutely not. Nobody (intelligent) disputes that there are natural, seasonal variations. The point is that the human contribution is now becoming more influential than the natural/seasonal variations and cycles.

that is not what he said .

I don't believe that. It's just you taking something out of context.

You stated that the southern half of Africa is showing elevated levels of CO2. The southern half of Africa contains quite a bit of non-tropical land.

Here is a NASA video that shows the fluctuation of CO2 throughout the year. Note that south Africa does show significant seasonal variation, though not as much as the northern hemisphere.
