The latent heat of fusion for water is 330 Joules/gram
It is obscenely exothermic This means that Hydrogen Peroxide is releasing heat to the surrounding environment, thus increasing the temperature.
in an endothermic reaction the reacting substances are releasing energy, making them feel cold. i don't know what you mean by evaporating heat, but you cannot create or destroy energy if that helps.
It is exothermic because it is releasing heat.
Combustion is another word for burning. It means a chemical reaction with an oxidising agent, usually oxygen itself, producing new substances and releasing heat.

moderates the climate by absorbing heat via evaporation and releasing it at higher latitudes as rain
