September 2020 ENSO update: La Niña is here!

La Niña conditions were present in August, and there’s a 75% chance they’ll hang around through the winter. NOAA has issued a La Niña Advisory. Just how did we arrive at this conclusion, and what does a La Niña winter portend? Read on to find out! By Emily Becker NOAA Checking the boxes Let’s revisit our La […]

Hurricane Laura: Spectacular before and after photos show scope of devastation in Louisiana

From August 27-31, the National Geodetic Survey (NGS) collected aerial damage assessment images in the aftermath of Hurricane Laura. Imagery was collected in specific areas identified by NOAA in coordination with FEMA and other state and federal partners. Collected images are available to view online via the NGS aerial imagery viewer. View tips on how to use […]

Watchdog accuses Trump’s NOAA of choosing extinction for critically threatened right whales by hiding scientific evidence

As the North Atlantic right whale was placed on the International Union for Conservation of Nature’s list of critically endangered species Thursday, environmental protection groups accusing the U.S. government of bowing to fishing and fossil fuel industry pressure to downplay the threat and failing to enact common-sense restrictions to protect the animals.

NOAA: July 2020 ENSO update: La Niña Watch!

ENSO is still in neutral, and likely to continue so through the summer. However, the 50-55% chance of La Niña developing in the fall and lasting through winter means NOAA has hoisted a La Niña Watch. By Emily Becker NOAA What’s a Watch? I’ve been writing these blog posts for more than six years now, and the terminology La […]

How hot will 2020 get? NOAA data shows an even chance of La Nina conditions in the Pacific

After several months of hovering above average, sea surface temperatures in the tropical Pacific have dropped rapidly in recent weeks. The current CPC/IRI ENSO forecast estimates about a 60% chance that ENSO-neutral conditions will remain through the summer. Chances for the fall and winter are about equally split between neutral continuing and La Niña developing, at around […]

Is climate change causing more ‘blocking’ weather events in the Jet Stream?

The past few months have seen some remarkable weather, from the UK’s sunniest spring on record to Siberia’s dramatic heatwave and “zombie wildfires”. Key to this unseasonable weather are persistent high-pressure “blocking” weather systems, which bring clear, dry conditions on the ground below for many days or weeks. By Robert McSweeney Carbon Brief Blocking events bat away oncoming low-pressure systems […]

Climate Change: Link between Earth’s heat and hurricane strength grows

Researchers from NOAA and the Cooperative Institute for Meteorological Satellite Studies have greater confidence that warming surface temperatures and increasing tropical cyclone intensity appear to go hand-in-hand. A new study in the Proceedings of the National Academy of Sciences (PNAS) indicates a significant global increase in hurricane intensity over a four-decade period, showing the emergence of more significant findings than previous […]

NOAA exploring impact of COVID-19 response on the environment

The coronavirus pandemic response has reduced pollution from a large number of sources across many geographic regions. NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans. By NOAA NOAA scientists are using the most advanced atmosphere-ocean models […]

National Climate Assessment: Hurricanes and hospital flooding

Think of a hurricane and you probably picture house-peeling winds. However, flooding usually inflicts the worst damage. Storm surges pose the greatest dangers to human lives and structures, and in damaging hospitals, storm surges can threaten both at once. By Michon Scott Rebecca Lindsey NOAA From Chapter 14 of the Fourth National Climate Assessment (NCA4), these maps show potential hurricane-caused inundation in Miami-Dade […]

Climate Change: 2018’s Billion Dollar Disasters in Context

NOAA’s National Centers for Environmental Information (NCEI) tracks U.S. weather and climate events that have great economic and societal impacts. Since 1980, the U.S. has sustained 241 weather and climate disasters where the overall damage costs reached or exceeded $1 billion (including adjustments based on the Consumer Price Index, as of January 2019). The cumulative cost […]
