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. Findings on changes in the private weather industry, 2017.
Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). References. Trenberth, K. & Fasullo, J.
It’s an arresting graphic, and follows in from the record high ocean surface temperatures that were being reported a month ago. Since the seasonal cycle over land is much larger than over the ocean (smaller heat capacity, and less evaporation), that means that the seasonal variations in the north outweigh the variations in the south.
For example, in 2017 nearly 200,000 residents had to be evacuated below the Oroville Dam due to fears of collapse after a rain-on-snow event. Oroville spillway damage in 2017. In past years, supercharged snowmelt has led to flooding and dam safety concerns.
However, on the level of basic physical reasoning, it is of course a no-brainer that warming will cause land-ice to melt (and melt faster as it gets hotter) and ocean waters to expand, so sea-level rise is the inevitable result. meters of rise by 2100. The Long Term Future.
2021) show that the trends in the EEI derived from CERES match what you get from the changes in ocean heat content. Satellite-derived trends in EEI compared to estimates from changes in ocean heat (Loeb et al., Koonin, "Earth's Albedo 1998–2017 as Measured From Earthshine", Geophysical Research Letters , vol. Shoumko, S.
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.
degrees Fahrenheit between 1951 and 2017.” Now, though, climate is changing rivers, lakes and oceans, forcing a renegotiation of our relationships to those bodies of water. ” Moreover, “average temperatures in the Great Lakes region rose 2.3 ” Climate change is hitting home right in the middle of the country.
By Emma Foehringer Merchant When wildfires spread through parts of Northern California wine country in 2017, they melted electronics, combusted cars and exploded propane tanks. The fires sent acrid smoke billowing into the sky, its footprint wafting over the state and extending for 500 miles into the Pacific Ocean.
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.
2020), and can cause an increase in vertical wind shear over the Atlantic ( Kossin 2017 ; Ting et al. 390-393, 2017. Bennartz, "The Role of Aerosols in the Evolution of Tropical North Atlantic Ocean Temperature Anomalies", Science , vol. All three of these factors have a powerful quelling effect on tropical storm formation.
Ocean Conservancy has compiled the data collected during this global volunteer effort on behalf of ocean health since the ICC’s start in 1986. Now, a new collaboration between Ocean Conservancy, PADI AWARE Foundation and scientists at CSIRO has resulted in the first global map of plastic hotspots. Never miss an update.
Meanwhile, less than 100 miles away from the governor’s office as the gull flies, a strong wind was blowing over the ocean south of Martha’s Vineyard. 1 megawatt-hour is 1,000 kilowatt-hours.)
By Deborah Pirchner, Frontiers science writer Image: Rob Lachlan As ocean temperatures rise, corals can lose their color due to heat stress. One of the worst mass bleaching events occurred in 2016 and 2017 on the Great Barrier Reef, causing bleaching on 91% of the system’s reefs.
The idea is to boost the natural process by which carbon dioxide in precipitation reacts with soils and rocks to form bicarbonate ions, which eventually find their way into oceans via rivers.
Based on the most comprehensive winter study to date, conducted in the Southern Ocean during July and August 2017, scientists were able to show that phytoplankton were indeed active during the icy cold and dark winter months. Read the full story from Stellenbosch University.
Six environmental groups launched the proceeding challenging the stay after EPA published notice of the stay in the June 5, 2017 issue of the Federal Register. filed June 5, 2017; emergency motion for stay granted July 3, 2017). June 29, 2017). June 28, 2017). June 28, 2017). filed June 9, 2017).

Conserve and Sustainably Use the Oceans, Seas and Marine Resources for Sustainable Development. By Val Fajardo, 3L Student at Vermont Law School.
About 90% of its farms are considered “family owned,” according to the 2017 US Department of Agriculture farm census. From 2002 to 2017, the most recent USDA farm census, the number of farms in Kings County declined 16.6%. Like its neighbors, Kings is intensively farmed. The data show that’s already happening.
A high proportion of plastic waste ends up in seas and oceans – estimates suggest that more than 250,000 tons of plastic debris are currently floating around in oceans all over the world. . Plastics are taking over the oceans.
In addition, it stores vast quantities of freshwater that if released to the ocean would rise sea level by tens of meters and interfere with saline-driven ocean currents that transfer heat around the planet. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018. Prof Martin Siegert in Antarctica.
Over a decade, from 2007-2017 , the direct costs of extreme weather events to the federal government was $350 billion. However, during half that time, from 2015-2021, the direct costs to federal government for disasters was $315 billion.
Abandoned, lost or discarded fishing gear—also known as ghost gear—is one of the most visually arresting forms of ocean plastic pollution. That’s why the Global Ghost Gear Initiative (GGGI) first released the Best Practice Framework for the Management of Fishing Gear (BPF) for Capture Fisheries, or C-BPF, in 2017. Never miss an update.

The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. It is even found in the polar oceans and the deepest ocean trenches.” and 10cm in size) for a different study.
In the past few years, physicists have begun to realize that it could have a major role in fluid dynamics – the Earth’s oceans, for example, or plasmas, or the biological cells in fluid-like “active” matter. First of all, the slim layers of the Earth’s atmosphere and oceans can be approximated as 2D. But how many waves?
By Delaney Dryfoos In San Felipe, a fishing town on the northeast edge of Baja California, the use and transportation of gillnets have been banned by the Mexican government since 2017 as a measure to protect the rare vaquita porpoise.
Single-use plastic items persist indefinitely in our marine environment, collecting in rivers, streams and ultimately the ocean, endangering and entangling wildlife along the way. Please try again or contact 1.888.780.6763 Enter Your Email.loading Thanks for signing up for Ocean Conservancy emails.
Wallner’s team has shed new light on this debate by analysing a core sample of Earth’s crust, taken from 1500 m below the surface of the Pacific Ocean. Among the most popular ideas is that r-process nuclides are produced during neutron star mergers – such as the event detected in 2017 by gravitational-wave and conventional telescopes.
We’re on track to see plastic outweigh fish in our oceans by 2050. million tonnes) between 2017 and 2021. The only way to reverse the plastic tide is to make, and use, less plastic in Canada and around the world. . Canada desperately needs an effective and comprehensive plan to tackle the plastic pollution crisis.

The same plastic that becomes the take-out packaging and single-use items that clog up our landfills, natural areas and oceans. There were at least six spills of toxic substances reported at Sarnia-area NOVA plants between 2017 and 2020. It was fined another $125,000 in 2018 for a spill of brine into a Sarnia-area waterway.
Ocean ecosystems, Indigenous cultures, commercial and recreational fishing, and coastal livelihoods and economies—all of these rely on abundant fish populations. It’s clear that in many ways, progress has stalled or even started to reverse entirely: Since 2017, the number of overfished stocks has jumped from 35 to 49.
Candidate in the Department of Chemistry at Colorado State University Every minute, one garbage truck worth of plastic is dumped into our ocean. Between plastics and the health of our oceans? Production, use, and fate of all plastics ever made, Science Advances , 2017 , 7 , 25-29. Why is that a problem? Jambeck, J.,

Deep in the Pacific Ocean, a strange, diaphanous balloon drifts by. Taking inspiration from nature isn’t new, but marine biomimetics is relatively nascent partly because just 5% of the ocean has been explored. Meanwhile, animals such as the ram’s horn squid have inspired better ways to explore the ocean itself. trillion and $5.7
My family and I think octopuses are the most marvelous animals in the ocean. You probably don’t have to worry about encountering one of these enormous creatures as they live about 6,000 feet beneath our ocean’s surface. In 2017, a sister species was discovered and dubbed the frilled giant Pacific octopus.
High crop losses from recent hurricanes, including Maria in 2017, resulted not only from direct impacts from the storms but also from related energy, telecom and water supply outages along with damage to roads and irrigation systems. Extreme events in the Northwest will include storms resulting from atmospheric rivers over the Pacific Ocean.
The two bureaus stated their focus for fiscal year (FY) 2022 would be on the development of regulations to address the IIJA requirement; accordingly, both BOEM and BSEE have budgeted funds for FY 2023 to develop such a framework.
