Broadcast September 3, 2019 – America This Week – Eric Bolling
The debate segment took a closer look at Hurricane Dorian and whether storms are getting worse and caused by climate change. More here & here.
Bolling was joined in this debate by hydrologist Fernando Miralles-Wilhelm and, the chairman of the Atmospheric and Oceanic Science Department at the University of Maryland and Marc Morano the founder of ClimateDepot and a skeptic of the climate change consensus. Professor Miralles-Wilhelm is also with The Nature Conservancy.
Extreme weather expert Dr. Roger Pielke Jr.
: On hurricanes – and more generally, tropical cyclones — we are fortunate that there have been two recent consensus statements of experts produced by the World Meteorological Organization (WMO, Part 1
and Part 2
) and the National Oceanic and Atmospheric Administration
(NOAA). These statements, along with the work of the Intergovernmental Panel on Climate Change (IPCC
) and U.S. National Climate Assessment (USNCA
) provide a robust and reliable guide to the current views of relevant experts on the science of hurricanes and climate change.
“an anthropogenic influence has not been formally detected for hurricane precipitation,” but finds it likely that increases will occur this century. Similarly, the WMO concluded
, “no observational studies have provided convincing evidence of a detectable anthropogenic influence specifically on hurricane-related precipitation,” but also that an increase should be expected this century
…The WMO assessment concludes: “anthropogenic signals are not yet clearly detectable in observations for most TC (tropical cyclones) metrics.”
Hurricane Dorian stats:
– 185 mph lifetime maximum sustained winds – tied with Gilbert (1988) and Wilma (2005) for the 2nd strongest maximum sustained winds in the Atlantic basin
since 1950. Allen (1980) had maximum sustained winds of 190 mph.
– 910 hPa lifetime minimum central pressure – tied for 9th lowest pressure
Note: Pressure records are not consistently reported in the Atlantic hurricane
database prior to 1980.

Since 1999, the University of Maryland’s Earth System Science Interdisciplinary Center has collaborated with NASA’s Goddard Space Flight Center to research climate change, the composition of the atmosphere and the carbon and water cycles. On March 15, NASA awarded the ESSIC a $64.8 million five-year cooperative agreement that will allow the center to continue its research on Earth systems science.Fernando Miralles-Wilhelm, interim director of ESSIC and professor of atmospheric and oceanic sciences at this university, said this is the largest of four agreements ESSIC has received from NASA since its formation. He added that the amount of funding awarded by NASA has grown steadily as the ESSIC’s research abilities have expanded.
Fernando Miralles-Wilhelm, a professor at the University of Maryland, agrees that the patterns are due to global warming. He is chair of the university’s Department of Atmospheric and Oceanic Science and a professor in the department.
Miralles-Wilhelm said higher temperatures are drawing more water vapor from the Earth’s surface and dumping it in the form of prolonged rainfall. He used the analogy of a simmering tea kettle to illustrate the point.
As the water in the kettle gets hotter, the boiling bubbles become more rapid. “These storms are essentially like those bubbles,” Miralles-Wilhelm said…
In response, Miralles-Wilhelm said it’s important to “separate the signal from the noise.” The noise may be an isolated weather event that delivers any number of characteristics. But the signal is a long-term pattern showing global warming, Miralles-Wilhelm said. “If you look at the record, it’s clear,” he said.
