Great Lakes water levels at or above average for next 6 months

NOAA and Army Corps issue forecast, consider El Niño potential impact

Scientists from NOAA, the U.S. Army Corps of Engineers and Environment Canada have issued a six-month forecast for water levels to be at or above average on Lake Superior, Michigan, Huron, and Erie into spring of 2016. Lake Ontario water levels are expected to remain close to monthly averages. However, the impacts of the anticipated strong El Niño and other atmospheric anomalies on the forecast are difficult to predict.

HFC greenhouse gases: a tale of two (or more) futures

New research projects greenhouse effect from substances that replaced ozone-depleting products

new paper appearing online in Atmospheric Environment  coauthored by researchers at NOAA’s Earth System Research Laboratory looked at the climate implications of various proposals for future HFC use that are being discussed this week under the United Nations Montreal Protocol, the global agreement that protects the ozone layer. 

Annual Antarctic ozone hole larger and formed later in 2015

The 2015 Antarctic ozone hole area was larger and formed later than in recent years, according to scientists from NOAA and NASA.

On Oct. 2, 2015, the ozone hole expanded to its peak of 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North America. Throughout October, the hole remained large and set many area daily records.

Warming waters a major factor in Gulf of Maine cod collapse

New study shows how warming complicates fisheries management

For centuries, cod was the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks in the gulf are on the verge of collapse, hovering at 3-4 percent of sustainable levels. Even setting tighter limits on fishing has failed to slow this rapid decline. Now a new

 report in Science concludes that rapid warming of Gulf of Maine waters— warming in the last decade faster than in 99 percent of the global ocean —has reduced the capacity of cod to rebound from overfishing, leading to collapse.

The United Nations Intergovernmental Panel on Climate Change (IPCC) elected NOAA’s Ko Barrett to serve as one of three vice chairs for the international body. The IPCC was created to review and assess the most recent scientific, technical, and socio-economic information produced worldwide that is relevant to the understanding of climate change.

Low-oxygen waters off Washington, Oregon coasts risk becoming large 'dead zones' Read more

A large area of poorly oxygenated water is growing off the coast of Washington and Oregon. Scientists say oxygen levels may fall low enough to create "dead zones."

2020’s Economic Slowdown Provides Opportunity to Investigate Ozone Pollution in the U.S. Read more

When COVID-19 pandemic began in the US, counties and cities across the nation imposed stay at home orders, closed schools or imposed travel restrictions. From March 2020 onward, many Americans hung up car keys and settled into their homes for work and school. Traffic patterns dramatically changed, and previously smog filled vistas became clearer.

Human activities responsible for rapid increase in Earth's heat

Human activities responsible for rapid increase in Earth's heat Read more

A new study by Princeton University and NOAA researchers has found clear evidence of human influence on Earth’s climate in the past two decades of satellite measurements. “Human activity strongly influenced the positive trend in Earth's energy imbalance, causing a significant increase in the heat stored in the planet,” said Shiv Priyam Raghuraman, the lead researcher on the study.
