For comparison, it's almost easier to boil water than to melt it from 0C ice to 0C water.
* 334kJ/kg for water to melt it
* 418kJ/kg for water to raise from 0C to 100C
Let's re-evaluate your statement with the key information that you omitted in your post: * 334kJ/kg for water to melt it * 418kJ/kg for water to raise from 0C to 100C * 2257 J/g is the heat of vaporization of water
You'll notice that the heat of vaporization is an order of magnitude larger than your other metrics. Thus, it is much much harder to boil water than to melt it!
Oh really? Well, isn't it odd that for the first time in history a denier forgets to mention increased water vapor in the atmosphere?
