Am I still allowed to question climate change?

[Cyclone]

If humans hadn’t burnt the fossil fuels, and chopped the trees down there would be less CO2 in the atmosphere and the planet would be cooler.

There would be less CO2.

 

You don't know that the planet would be cooler, because the concentration of atmospheric CO2 doesn't appear historically to be that strongly correlated with the temperature.

 

 

 

I agree, unfortunately many don't because of Japan and chernobyl.

 

Wind is seen as a safer option.

Japan was actually a demonstration of just how safe a modern nuclear plant is. The earthquake and tsunami were about the worse possible things that could happen together to that plant, and yet minimal radiation was released and no one has been harmed by it (measurably).

To come to that conclusion would need significantly more information than is available. High CO2 with low output for the sun could result in a cooler planet than low CO2 and high output from the sun, giving the false impression that CO2 doesn’t cause the planet to warm up. CO2 traps heat which is easily proven.

I agree but that doesn't alter the fact that many people fear nuclear power.

Most climate specialists believe that the current predictions of a maximum 18-59cm rise by 2100 made by the Intergovernmental Panel on Climate Change are likely to be significantly underestimated.

 

Predictions of such a change are highly uncertain due to a lack of scientific understanding.

Ok, where is the water supposed to be comming from then???

 

I am capable (well it's Fking easy) of calculating the effect on sea level of whatever melting or expansion or whatever you propose.

 

Which ice do you think is vunerable to melting? bear in mind that a 1 degree © increase in temperature will alter the snow line/perminent ice line by 100m in altitude. Physics. What the Fk do you think is going to melt by what temperature rise by when???

There has been a 1 degree warming since 1900, I dont know what the weather was like back in 1900, but I know that we had much colder winters back in the 1970s. Perhaps that was just local weather, what about the climate of the rest of the world?

You can remember the temperature of the last several thousand years, shall we call you Methuselah?

The world is hottest it has been since the end of the ice age - and the temperature's still rising

The world is hottest it has been since the end of the ice age - and the temperature's still rising

Apart from the medievil warm period and of course the bronze age warm period. The bronze age one lasted several thousand years, infact 3 ish thousand years.

 

The world appears the have a climate which varies between upper and lower limit (the lower one is unpleasant, frost fairs.. starvation..). Whilst there maybe, or probably, is a heating effect of increased low levels of CO2 (it's a very low level of abundnce), the sensitivity of the climate to it is in question, or if you go with the laterest (or recent.. I hate to try try be more informed.. I'm not.. just a spectator) the degree of heating (thermal forcing) from a doubling of CO2 is less than 1 Watt per square metre. Less than 0.3 degree.

 

This is utterly tiny. And benificial!

 

If the sea level rise associated with such an event is minor to un-noticeable and the benifits of increased fertility, especially in the tropics, and this wonderful lifestyle of world travel, abundante tecnology (like the ipad) which can only happen if there is a multi-billion world market and all the rest why be up-set??? Enjoy the fruits of industry!!! Be happy!!!

Where do you get the basis for your calculations from?

 

There is more than one greenhouse gas!!

Like this one.

 

Thawing permafrost releases methane, a powerful greenhouse gas, but this has not yet been included in models of the future climate. Permafrost covers nearly a quarter of the northern hemisphere at present and is estimated to contain 1,700 gigatonnes of carbon – twice the amount currently in the atmosphere. As it thaws, it could push global warming past one of the key "tipping points" that scientists believe could lead to runaway climate change.

The royal society says that there is a 3.6 watts per square meter thermal forcing from a doubling of CO2. This includes secondary effects of other gasses.

[El Cid]

Which "royal society"?

Probably this one.

There is strong evidence that the warming of the Earth over the last half-century has been caused largely human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.
