Notes on Storms in a Warming Climate
Storms on a Warmer Earth
Energy Source of Storms:
The energy that drives hurricanes and storms originates from the solar heating of tropical oceans.
The sun's energy warms the ocean water, and this warm water subsequently provides the energy for storms.
Initial Hypothesis vs. Reality:
One might logically assume that a warmer Earth would lead to more frequent and/or more energetic storms.
However, this straightforward assumption may not necessarily be accurate due to complicating factors.
Complexity Introduced by Wind Shear:
The relationship between a warmer Earth and storm activity is made complex by shifting wind patterns, which are themselves a consequence of global warming.
These changing wind patterns can result in an effect known as "wind shear."
"Wind shear" has the potential to reduce the energy of storms, counteracting the expected increase from warmer waters.
NOAA's Role and Findings:
The National Oceanic and Atmospheric Administration (NOAA) is a U.S. federal agency tasked with monitoring climate and the environment and implementing preservation efforts.
NOAA has conducted extensive studies on the relationship between warming and storms but has not yet reached a definitive conclusion regarding the overall impact.
NOAA Projections on Regional Hurricane Activity:
A summary of many studies by NOAA indicates regional differences in projected hurricane activity:
West Pacific and Indian Ocean: Climate models consistently project an expectation of more and stronger hurricanes in these regions.
Atlantic and East Pacific Ocean: The models are less conclusive, and it remains unclear whether these areas should expect more frequent or stronger storms.
Implications for North and South America:
For populations living in North and South America, further data collection is necessary to ascertain if these regions will experience an increase in storm frequency and/or intensity.
Impact of Rising Sea Levels on Storm Damage:
Increased Damage: Regardless of whether storms become more frequent or violent, rising sea levels are projected to cause significantly more storm damage.
Storms are already having a more severe impact due to elevated sea levels.
Exacerbated Situation: Should it be confirmed that storm frequency and/or severity do increase due to higher global temperatures, the overall situation regarding storm impacts would become "much more severe."
Financial Costs of Hurricanes in the U.S.:
According to Bloomberg News, hurricane damage in the United States reached in 2005.
Scientific Debate on Climate Change Link:
While scientists largely agree that human activities are warming the planet, there is less consensus regarding the exact resulting effect on hurricanes.
There is also considerable debate concerning the degree to which rising storm costs in the U.S. can be attributed to climate change.
Storm costs in the U.S. have reportedly increased at an average rate of million per year over the last century, according to Estrada.
