How do we measure global warming?

Measuring ocean temperatures seems to be common, but I liken this to measuring the temperature of a glass of ice water. A large amount of added heat will go into overcoming the latent heat of fusion of the ice to melt it, rather than raising the temperature of the water. It takes 4.1813 Joules of energy to raise the temperature of one gram of water one degree Celsius, but it takes 334 Joules of heat to melt that same one gram of ice once it is at 0° C. Do you think that popular science is measuring global warming in a way that does not clearly show what is happening?!

    Ice at zero degree Celsius turns into water at zero degree Celsius without the rise in temperature, due to latent heat of fusion.So, when there's no change in temperature, how could this be global warming?Global warming buffs always say that temperature of the planet rise by so many degrees over a decade or so, but it clearly conflicts the ice melting principles.

    According to me, it's the air temperature.Global warming is nothing, but heat from outer space getting trapped in atmosphere due to the presence of greenhouse gases(just for those who believe in that theory).So, heat is again radiated back from earth and ocean bodies, but get trapped in atmosphere and goes on for a circulation.Hot air coming in contact with any thing, heats it up due to convection.

    Have you seen Waterworld? I think measuring the recession of polar ice is the best way to see how much trouble we're in.
