    In my opinion best thing would be an agreement among Governments all over the world with precise targets on CO2 concentration in the atmosphere to be achieved in the following, let's say, 40 years.
    If this will not happen you are right, we will be forced to do some geo-engineering to actively remove it from the air.
    Trying our best at a personal level isn't going to do much.

    We need government involvement.

    Agree 100%. In this thread I proposed the establishment of an International Organization giving directions concerning anti-pollution standards to Governments all over the world, but my proposal didn't have much success among TMC Members.

    As I say in my post #232 I also found out that UNFCCC is an International Organization dealing with environmental problems.

    But I think that we should do even better if we want to decrease CO2 concentration in the atmosphere.
    Raffy, it is considerably more complicated due to the diminishing capacity of the oceans to absorb additional carbon dioxide, the formation of carbonic acid in the oceans and positive feedback effects giving rise to further releases of GHGs and warming. The following article from yesterday's Globe and Mail discusses the first two of these issues. See:

    http://www.theglobeandmail.com/techn...02/?cmpid=rss1

    A very large amount of the carbon dioxide that we emit every year by burning the fossil fuels ends up in the ocean … it used to be … probably over the last 200 years as much as 50 per cent is dissolved in the ocean.

    Much less is dissolving now because the chemistry of the ocean is changing. As we add more and more CO2 to the oceans, the ability of the oceans to take up more CO2 goes down. In fact, it’s filling up with CO2 and taking less and less out of the atmosphere.

    That means more and more stays in the atmosphere, which drives more and more climate change. This changes the heat balance of the Earth and is causing our climate to become warmer … there are predictions that with a warmer planet comes more extreme weather conditions.

    What do you hope your research will lead to?

    A better understanding of how much CO2 will remain in the atmosphere 50 to 100 years from now. … If you put something into the atmosphere as a result of deliberate activity, whether that’s driving a car or turning on your TV, then I think you have a responsibility to understand what is happening with that. … CO2 in the ocean is an acid, so we are actually making the oceans slightly more acidic with time and because the ocean acidity has always been … invariant … there are some concerns that what we are doing right now may be affecting the viability of sea water as a habitat for certain forms of life in the future.

    Agreed. The dumping of pollution of any type into the global commons requires government action to either directly regulate the pollution or else to put a price on the pollution such that market forces indirectly regulate the emissions.

    That is correct. The ceiling amount of 450 PPM of CO2 has been widely recognized as a "do-not-exceed" limit, associated with a likely temperature increase of 2 deg C. By way of background, human activity has increased CO2 levels from around 280 PPM to 400 PPM since the beginning of the industrial revolution (when we began to burn serious amounts of fossil fuels). We are currently increasing levels by around 3 PPM per year, and the volumes are still increasing. While the problem is well understood, and the solution, namely putting a price on carbon, is also clear, there are political impediments (principally erected by industry lobbyists and PR types) to effective action. For information on the CO1 levels see:

    I thought it was closer to 2 ppm per year, but regardless, 450 ppm is going to be exceeded by 2050. USA and Europe might be releasing slightly less CO2 this year than we did last year, but we're still releasing lots of carbon from fossil fuels with no realistic end in sight. Temperatures will increase, oceans will rise and become more acidic. Some anthropogenic climate change is inevitable. The question is how much. A 3°C rise would be preferable to a 6°C rise.

    Now all we need is to get Danica Patrick on our side!! We've got Leilani!

    And Leilani's a lot smarter, it seems. Teslas, Vegetarian, etc., etc., and a girl. I know several girls who would claim that such a combination is a winner.

    I'll say it before someone else does:
    "Girls don't know anything about cars."


    ETA til Bonnie arrives with the smackdown...7 posts.

    Leilani, please prove me wrong by letting me ride-along sometime.

    As Bonnie already gave many evidences it is not true that girls don't know anything about cars. Also Leilani gave in this article:

    http://www.huffingtonpost.com/leilan...b_3327721.html

    evidences of being very clever and understand a lot about cars and not only cars.

    Ok in Italy I see women doing unbelievable things while driving . But it's only a matter of getting used to it .

    I think Raffy missed my sarcasm.
