Not exact matches

[ANDY REVKIN notes: One reason for the statistical gridlock is the murkiness of the data on the things that matter most (hurricane trends over the past century, for instance).

What is fairly hypocritical is to publicly claim that the data over the past few centuries is good enough to support this AMO explanation for hurricane activity, while at the same time claiming that the data is too poor to produce a statistically relevant trend over the past few decades.

Their work encompasses a range of problems and time scales: from five - day model predictions of hurricane track and intensity, to understanding the causes of changes in extremes over the past century, to building new climate prediction models for seamless predictions out to the next several years, to earth system model projections of human - caused changes in various extremes (heat waves, hurricanes, droughts, etc.) over the coming century.

The trend in numbers of major hurricanes making landfall in the United States has been slightly downward over the past century.

The models heavily relied upon by the Intergovernmental Panel on Climate Change (IPCC) had not projected this multidecadal stasis in «global warming»; nor (until trained ex post facto) the fall in TS from 1940 - 1975; nor 50 years» cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005); nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007); nor the onset, duration, or intensity of the Madden - Julian intraseasonal oscillation, the Quasi-Biennial Oscillation in the tropical stratosphere, El Nino / La Nina oscillations, the Atlantic Multidecadal Oscillation, or the Pacific Decadal Oscillation that has recently transited from its warming to its cooling phase (oceanic oscillations which, on their own, may account for all of the observed warmings and coolings over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004 hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.

Although fluctuating sea level rises over the past several centuries have averaged about 7 inches, and continue to rise at that rate with no evidence of acceleration, land subsidence and hurricane risks are ever - present issues that must be taken into account.

Sea level has risen by roughly 15 centimeters (6 inches) over the past century, while hurricanes have become more severe in the Atlantic and North Pacific.
