They strengthen
over warm water, such as that around Florida, and rising temperatures create more
water vapor in the atmosphere,
intensifying rainfall.
Perhaps all of this newly freed up ice - cold
water at the poles is temporarily acting as a negative feedback, but as it absorbs more of the solar radiation,
over time, it will transform into what we rightly think: a predominately positive feedback system, rapidly
intensifying the
warming.
However, all other factors being equal, many studies and observations reveal that hurricanes
intensify as they pass
over patches of
warm water.
This has been observed when Atlantic hurricanes
intensify as they crossed
warm water rings from the Gulf Stream (Effects of a Warm Oceanic Feature on Hurricane Opal, Shay et al 1999 AMS), as well as in the case of Katrina, which intensified rapidly to Cat 5 over an unusually warm Gulf of Mex

intensified over the Gulf (historically rare behavior for hurricanes to do that).
My own guesstimate starts with events that have either been formally attributed (in a probabilistic way) to climate change — an example is the 2003 European heatwave — or which have a demonstrable link to physical processes consistent with a climate influence — examples include Hurricanes Katrina and Sandy, both of which were observed to rapidly
intensify over unusually
warm waters.
But was it not scientists, with their words printed in the Guardian, repeated by policy - makers, which warned of «Arctic death spirals»; «ice - free Arctic summers»; the proliferation of disease; worsening,
intensifying and increasing frequency of storms, flood, drought and fire; dramatic decreases in agricultural productivity in Africa; increased
