What dictates a hurricane’s strength?
There are many ways to categorize a hurricane. The storm’s central pressure is one way. The height of its storm surge is another. How much rain it drops is another. And, of course, the strength of its wind is another. But what causes a hurricane to strengthen or weaken? The answer is simple enough, but multifaceted.
"Alarming year for extremes": 2021 saw record-high greenhouse gas, ocean heat and sea levels rise, new report finds
"With many communities hit with 1,000-year floods, exceptional drought and historic heat this year, it shows that the climate crisis is not a future threat but something we must address today," one NOAA administrator said.cbsnews.com
Managers of New York Fish Dealer Plead Guilty to Fishing Fraud Conspiracy
On April 20, a federal grand jury indicted Christopher Winkler, Bryan Gosman, Asa Gosman and Bob Gosman Co. Inc. with one count of conspiracy, among other crimes. Bryan and Asa Gosman admitted that this fish was then sold to a now-defunct company, an unindicted co-conspirator, in the New Fulton Fish Market in the Bronx, New York. Both Asa Gosman and Bryan Gosman had an ownership interest in the defunct company. In court documents, Bryan and Asa Gosman admit that the sales of illegal fish (to both companies) totaled at least $240,000 wholesale. Bryan and Asa Gosman stated that part of the conspiracy was to falsify both FVTRs and dealer reports to cover-up the fact that fish were taken in excess of quotas.justice.gov
New York Fisherman and Fish Dealer Charged with Conspiracy, Fraud, and Obstruction
Today, a federal grand jury in the Eastern District of New York unsealed the indictment of one fisherman, a wholesale fish dealer, and two of its managers for conspiracy to commit mail and wire fraud and obstruction in connection with a scheme to illegally overharvest fluke and black sea bass. This fish was then sold to a now-defunct company and unindicted co-conspirator in the New Fulton Fish Market in the Bronx. The overages of fish included at least 74,000 pounds of fluke, and the overall over-quota fish (of all species) were valued at least $250,000 wholesale. Similarly, the first company that buys fish directly from a fishing vessel is termed a fish dealer, and fish dealers are required to specify what they purchase on a federal form known as a dealer report, which is transmitted electronically to NOAA. An indictment is only an accusation, and the defendants are presumed innocent until proven otherwise before a jury at trial.justice.gov
Greenhouse gas levels surged in 2020, NOAA says

2020 is "effectively tied" for warmest year on record
The conclusion: 2020 was nearly tied with 2016 for the warmest year globally on record. Global temperature departures from average in 2020 Berkeley EarthNOAA concludes the United States had its fifth warmest year on record, with all five of the warmest years occurring since 2012. NASA's GIS dataset shows 2020 as the warmest year, but only by a minuscule margin, whereas the NOAA and Berkeley Earth data show 2020 a hair behind 2016 for the warmest year globally on record. Comparison of various datasets on global temperatures Berkeley EarthAlthough we have come to expect each new year to be one of the warmest on record, 2020 should not have been able to reach such heights. Rohde from Berkeley Earth says 87% of the Earth was significantly above normal in 2020 and 10% saw record average annual warmth.cbsnews.com
Climate change is responsible for billions of dollars in flood costs, study says
Now a new study from Stanford University puts a number value on the portion of the increasing costs caused specifically by the rise in floods linked to climate change. That's important because, with the impacts of climate change continuing to mount, there's an urgency among scientists and economists to quantify how much climate change is costing us and how much it may cost us in the future. A series of studies after Harvey found that climate change resulted in the storm dumping up to 38% more rainfall than it otherwise would have. Together, these analyses revealed that climate change has contributed substantially to the growing cost of flooding in the U.S. That's because as the planet gets warmer, the impacts of climate change increase exponentially.cbsnews.com
"Alarming" and "extraordinary" rate of change as the Arctic warms, NOAA report says
That's according to an international team of 133 researchers from over a dozen countries who contributed to the 15th annual NOAA Arctic Report Card, released on Tuesday. In the a video accompanying the report, NOAA says there have been "alarming rates of change observed" since the 2006 Arctic Report Card, and adds, "the rate of change has been extraordinary." That was part of a several months long heat event which climate scientists said was made 600 times more likely by human-caused climate change. NOAAThe cause of the rapid warming is straightforward and well understood: It is human-caused climate change. Since 1981, June Arctic snow cover extent is decreasing at a rate of 15% per decade.cbsnews.com
NOAA releases 2020-2021 winter forecast, expecting warmer temperatures in the South
Your Local Weather Authority is in the process of making its forecast for the upcoming winter. Experts at NOAA are forecasting warmer than average temperatures across the southern half of the United States. What the La Niña typically meansThe main reason for a forecast like this has to do with the La Niña, which is described as cooler than average temperatures in the Pacific Ocean. What a La Niña meansWe reconstructed a map from the North Carolina Climate Office to show what a typical La Niña looks like across the U.S. during the winter months. In fact, one out of every four La Niña winters exceed expectations.

Roanoke fighting urban heat island through city-wide temperature mapping project
ROANOKE, Va. Studies have shown that afternoon temperatures in cities rise 15 to 20 degrees higher than surrounding rural areas. This is known as the urban heat island and it can cause an increased risk for respiratory illnesses, heat exhaustion and stroke and other factors. Why we should care about urban heat islands (WSLS)The city of Roanoke has identified this as a problem and applied for a grant from NOAA to work toward a solution. NOAA Climate and Health Project manager Hunter Jones said the city will be able to use that information to combat the urban heat island. How to fight urban heat islands (WSLS)Jones said the mapping process will take a few months and he expects the data to be ready by late fall or early winter.
NOAA joins Colorado State University by upping its 2020 hurricane forecast
ROANOKE, Va. The National Oceanic and Atmospheric Administration issued an update to its forecast for the rest of the Atlantic hurricane season. Similar to Wednesdays forecast from Colorado State University , NOAA is forecast an extremely active season ahead. The warmer the water is, the more conducive it becomes for tropical systems to grow and intensify. Wind shear refers to the difference in wind speed and direction from the ground up. If we make it beyond 21 named storms, storms will take on Greek letters as their names.
