Guest commentary by Robert Hart, Kerry Emanuel , & Lance Bosart The National Weather Service (NWS) and its parent agency, the National Oceanic and Atmospheric Administration (NOAA), delivers remarkable value to the taxpayers. This efficiency can be demonstrated by its enormous return on investment.
Whats the point of a beach adventure if you cant even go into the ocean? How does raw sewage end up in our oceans and rivers? In some cities, a combined sewer system means that usually both wastewater and stormwater get treated to the same high standards before releasing into the ocean. San Francisco City and County v.
Both hurricanes were exacerbated by warmer ocean surface temperatures, and are examples of “what hurricanes will look more like in the future,” according to Dr. Marc Alessi, an atmospheric scientist with the Union of Concerned Scientists. To put that into perspective, that’s enough to power about 7.5 – 10 million homes. million.
Unlike in years past, there is no longer any serious discrepancy between the records – which use multiple approaches for the ocean temperatures, the homogenization of the weather stations records, and interpolation. Southern Ocean trends. The least visited part of the ocean are the waters around Antarctica. References.
The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level.
There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. CO 2 also has an additional effect: it makes the oceans more acidic when dissolved in seawater. mm increase every year.
Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.
Think about what is involved – biological proxies from extinct species, plate tectonic movement, disappearance in subduction zones of vast amounts of ocean sediment, interpolating sparse data in space and time, degradation of samples over such vast amounts of time. All of which adds to the uncertainty.
A simple statement that masks just how complicated the issues are: mixing politics, economics, livelihoods, fisheries and endangered species in the ocean body that is the Gulf of Maine. He was on to something And the lobsterman was correct: we can blame carbon emissions for ocean acidification and warming in the Gulf of Maine.
The IPCC calls this a “robust acceleration ( high confidence ) of global mean sea level rise over the 20th century”, as did the SROCC in 2019. That’s because huge ice sheets take a long time to melt in a warmer climate, and the ocean waters take a long time to warm up as you go further down, away from the surface.
The Tribunal acted both boldly and conservatively by interpreting UNCLOS as an independent source of international legally binding obligations to address climate change and ocean acidification. The standard of due diligence under article 192 is … stringent given the high risks of serious and irreversible harm to the marine environment” (para.
Seagrasses Turn Back the Clock on Ocean Acidification. Expansive Study Shows Seagrass Meadows Can Buffer Ocean Acidification. Spanning six years and seven seagrass meadows along the California coast, a paper from the University of California, Davis, is the most extensive study yet of how seagrasses can buffer ocean acidification.
For the third consecutive year, Ocean Conservancy will be represented by an NFL-player for the league’s My Cause My Cleats campaign at this Sunday’s game.

1 Average number of named storms by day of the year in the historical record from 1851–2019 (dark blue line). 2019 ; Kossin et al. 1987-2007, 2019. The light blue shading denotes the range between the minimum and maximum number of storms observed by each day. Walsh, and L. Emanuel, and A. 447-458, 2013. 390-393, 2017.
The SWOT mission, as its called, will measure weekly changes in the world’s major rivers, lakes, wetlands, and oceans. For oceans, the satellite will track small-scale currents and eddies that transport nutrients, salt, and heat. The mission will launch before sunrise on December 15. It will gather extensive data.
By now, we all know the damage single-use items can do to our ocean and the creatures that call it home. That’s why thousands of people have taken Ocean Conservancy’s pledges to reduce waste in their daily lives by skipping the straw and quitting the cutlery. Thanks for signing up for Ocean Conservancy emails.
Lead author Adam Gold , a watershed researcher for the Environmental Defense Fund, said the wild uncertainty is because the court arbitrarily created a new standard for federal protection divorced from the science of how wetlands support larger streams, rivers, lakes and the ocean.

Judging from a 2019 report , the drivers of lake level variability are still not well understood. That record lasted just one year: In May 2019, 8.25 Now, though, climate is changing rivers, lakes and oceans, forcing a renegotiation of our relationships to those bodies of water. inches of rain fell. inches soaked the city.
Jumping size brackets, in 2019 a new species called Sato’s beaked whales was identified in the North Pacific , and in 2021, the 40-foot-long Rice’s whale was formally recognized in the Gulf of Mexico.

Cyclone Mocha, which made landfall in Myanmar earlier this week, is tied for the strongest storm ever recorded in the North Indian Ocean. Mocha is tied for the strongest storm ever recorded in the North Indian Ocean. Extreme rains and a warmer climate are uprooting fishing and farming in Trinidad and Tobago.
It works for progress on methane pollution, clean electricity, clean transportation, forests, fisheries and oceans, healthy communities, fuels and feedstocks, agriculture, water, food, carbon markets and other critical environmental challenges.

New research implicates emissions from the 2019-2020 Australian fires in the emergence of a three-year super La Niña that fueled droughts in Africa and hurricanes in the Atlantic.
About 80 per cent of the carbon dioxide released by Australia’s huge wildfires of 2019-2020 was captured by ocean algal blooms that grew due to the iron-rich ash
The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other. Furthermore, the volume of the oceans increases from the melting of land ice. The global sea level acts like the mercury in a thermometer because warmer water expands.
The Sabin Center wrapped up Climate Week NYC last Friday with an event exploring the opportunities and challenges posed by ocean-based carbon dioxide removal (CDR). As evidenced by the 150-plus people in attendance, ocean CDR is attracting growing attention as a possible climate change mitigation option. ground rock) into the ocean?
It’s been more than two years since Ocean Conservancy’s Florida Conservation Program launched Shores Forward , our flagship initiative to create positive change for our ocean across Florida. We now bring these successes to Tallahassee where we advocate and help craft legislation that protects our ocean.
In adopting this law, California joins a handful of other states with extended producer responsibility laws on the books, which brings me back to the history: A substantially different version of this bill failed in an end-of-session vote in 2019.
This quote came to mind as we at Ocean Conservancy launched our latest report, Recommendations for Recycled Content: Requirements for Plastic Goods and Packaging. After all, this was not the first time that Ocean Conservancy has looked at the issue of recycled content. Thanks for signing up for Ocean Conservancy emails.
The total forcing from the trace greenhouse gases mentioned in Step 3, is currently (to 2019) about 3.3 The factor that quantifies this effect is called the ‘efficacy’ of the forcing, which for the most part is reasonably close to one, and so doesn’t change the zeroth-order picture (Hansen et al, 2005).
Heightened flood risk The National Oceanic Atmospheric Administration (NOAA) said in a recent outlook that about 44 percent of the United States is at risk of floods this spring, equating to about 146 million people.
See more wonderful ocean animals! Thanks for signing up for Ocean Conservancy emails. It’s dark, freezing cold and animals there are under a lot of pressure literally— the pressure in the deepest ocean trenches is equivalent to having a walrus stand on the tip of your finger. Sorry, but we failed to add you to the list.
In Australia , many of the same areas that endured brutal bushfires in 2019 and 2020 are now drowning in record-setting rainfall. Australia smoldered during the epic “Black Summer” bush fires of 2019 and 2020. The island nation has always been at the mercy of climate patterns such as La Niña in the oceans that surround it.
Ocean scientists and naturalists such as David Attenborough are keen to remind us often of the demise of the Great Barrier Reef and other coral reefs. Audrey Azoulay, Director-General of UNESCO added: “To date, we know the surface of the moon better than the deep ocean. By Anders Lorenzen. It was like a work of art”.

United Nations experts will assess plans to release treated radioactive water into the ocean from a closed nuclear power plant in Japan. million gallons of water during 2020, only one million less than during 2019, when tourism peaked on the island. A Chinese environmental activist devotes his life to a deteriorating lake.
The 2019–20 wildfires generated 700 million tonnes of carbon dioxide—but a lot of that might have been mopped up by phytoplankton in the ocean. -- Read more on ScientificAmerican.com.
They litter our oceans , they have been detected in everything from aquatic life to drinking water, and they take lifetimes or longer to decompose. In 2019, the World Health Organization called for more research on the effects of microplastics to the environment and human health.
On the back of the dark and sombre Intergovernmental Panel on Climate Change (IPCC) cli mate report released last week, the US government agency National Oceanic and Atmospheric Administration (NOAA) has confirmed that this July was the warmest month ever experienced on Earth.

The nice thing about this DAS technology is that it’s very, very difficult to get a traditional ocean-bottom seismometer or even hydrophones running in the Arctic environment. But now, instead of having a few ocean-bottom seismometers for a short period, we have 20,000 channels of seismic data. We hear ocean dynamics as well.
