Shepherd and Knutson capture many facets of the major arguments for “human” and “natural” causes in the “surge” in hurricane activity. Following Hurricane Katrina and the parade of storms that affected the conterminous United States in 2004–2005, the apparent recent increase in intense hurricane activity in the Atlantic basin, and the reported increases in recent decades in some hurricane intensity and duration measures in several basins have received considerable attention.
Following a recent report issued by the World Meteorological Organization, this perspective is much needed because policymakers, the public and media need a balanced perspective and an appreciation for how difficult this problem is.
J Marshall Shepherd comments:
“Hurricanes and related hazards can have significant social, economic, political, and health impacts and as such, there is a vested interested by all in having a clear picture of how these storms will change as the climate system warms.”
This article also provides a summary of theoretical considerations for why hurricanes are likely to be stronger in a warmer climate. The authors conclude that significantly more research - from observations, theory, and modeling - is still needed to resolve the current debate on whether or not a global warming influence on hurricanes is already detectable in the observed record.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
