How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.25, 26,27,28

Water vapour, carbon dioxide, methane and nitrous oxide — the so - called greenhouse gases (GHGs) in the Earth's atmosphere - create a natural «greenhouse effect» by «trapping» heat between the Earth's surface and the Troposphere (the atmospheric layer 5 to 10 miles above the surface).

Methane and nitrous oxide emissions from agriculture and other human activities add to the atmospheric burden of heat - trapping gases.

Unfortunately, atmospheric concentrations of heat trapping gasses are still rapidly rising due to an increasingly dangerous emission coming from global fossil fuel burning.

How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.18, 25,26,27 So the link between hurricanes and ocean temperatures is complex.

Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.

As their atmospheric concentration has increased, the amount of energy «trapped» by these gases has led to higher temperatures.
