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.
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. We need to stop burning fossil fuels immediately. million.
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.
Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
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.
The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).
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.
1 Average number of named storms by day of the year in the historical record from 1851–2019 (dark blue line). The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming. The days of formation for the 2020 named storms are shown by the red squares. Zhang et al.
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 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. 29, citing the Vienna Convention on the Law of Treaties, article 31).
are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. 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.
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.

Heightened flood risk The National OceanicAtmospheric 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. This includes most of the eastern half of the country, the federal agency said.
If the land data was contaminated by urban heating effects, we wouldn’t see similar warming in the ocean. Laut, "Solar activity and terrestrial climate: an analysis of some purported correlations", Journal of Atmospheric and Solar-Terrestrial Physics , vol. 2569, 2019. 27489-27492, 2000. 801-812, 2003. Rendiconti Lincei.
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.
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.
The National Oceanic and Atmospheric Administration awarded nearly $1.5 The tribe sued Enbridge in 2019 to remove a section of the 70-year-old pipeline in Wisconsin. ALGAL BLOOMS : The National Oceanic and Atmospheric Administration awarded $1.5 A federal judge ordered the energy giant Enbridge Inc. Looking Ahead.
Scientific reports on climate issues, as well as reports on the state of the ocean, its ecosystems, and the relevance of the ocean for climate change, play a central role in the opinion. 52-54) and acknowledged the critical role the ocean plays in regulating the climate system (para. 157 as used in para. 52, 54, 60 and 68).
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. By Anders Lorenzen. Photo credit: NOAA NCEI.
The 24-month study process begins with the Colorado Basin River Forecast Center, a team of scientists operating within the National Oceanic and Atmospheric Administration. This scenario is a replication of the years 1988 to 2019, and represents hotter and drier conditions that have settled over the basin. Click To Tweet.
The greenhouse effect is a popular name for the earth’s warming effect which occurs naturally when gasses in the atmosphere trap heat from the sun and prevent it from escaping back into space. C increase, the IPCC report states GHG emissions must be cut back by 43% by 2030 and 84% by 2050 (relative to 2019 levels). F), let alone 1.5°C
Consequently, the response to this advisory opinion request should consider the climate change regime set by the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement (Paris Agreement) concerning the ocean. However, ITLOS is not responsible for implementing the UNFCCC or the Paris Agreement.
Coast Guard icebreaker Healy will travel from the Bering Sea off the coast of Alaska through Arctic waters to the northern Atlantic Ocean. In the past, the Arctic Ocean–and the Northwest Passage in particular—was often choked with thick sea ice that made maritime voyages risky and arduous, even at the most favorable times of the year.
Blue whales, Balaenoptera musculus, make their homes in the planet’s vast open oceans where most migrate thousands of miles annually to feed, mate, and raise calves. There is also the Indian Ocean blue whale, Northern blue whale, and Pygmy blue whale. How Big Is A Blue Whale? One blue whale is approximately the weight of.
Wild-caught seafood from our ocean is no exception. Climate change is making the ocean warmer, more acidic and lower in oxygen. Northern shrimp, found in the northeast, are highly vulnerable to climate change, according to a climate vulnerability assessment done by the National Oceanic and Atmospheric Administration (NOAA).
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
Plastics are harmful pollutants that burden our economy and threaten the health of our environment including our wildlife, rivers, lakes and oceans. The CEPA listing is the first step in Canada’s efforts to curb the fatal flow of plastic into our oceans, and one we’re pleased to support in court.”. Background.
Higher expenditures are yellow, orange, or red” (Climate.gov 2019). National Oceanic and Atmospheric Administration. “This map shows projected changes in U.S. electricity expenditures by 2080-2099 compared to today. Lower expenditures are blue. Understanding rural attitudes toward the environment and conservation in America.
million has been given to pro-fossil fuel think tanks by Tory donors since the 2019 general election. million from fossil fuel interests, highly polluting industries, and climate science deniers since the 2019 election. Lord Moynihan donated £53,000 to Liz Truss in 2022, and £100,000 to Boris Johnson in 2019.
CO 2 levels in the atmosphere hit an all-time high in early May. We are seeing the consequences in bushfires, acidifying oceans and locust invasions – which could push millions of people in East Africa into hunger. Think of the atmosphere as a bathtub, and emissions as the water that flows from the tap.
2019 ) gives a good overview of Manabe’s particular philosophy of climate modeling which was very much focused on getting things to work, and not worrying too much about the details. The basic issue stems from the different timescales of the ocean and atmosphere. Manabe’s Climate Modeling. That paper ( Manabe et al.,
by Lena Beck Dr. Ailene Ettinger joined TNC in 2019 as a Quantitative Ecologist. How is your work contributing to the reduction of greenhouse gases in the atmosphere? Most recently, Dr. Ettinger has been focused on climate change mitigation research of on-the-ground efforts such as planting trees. How is equity showing up in your work?
The only region of cooling is the northern Atlantic, where climate models have long predicted just that due to a slowing of the Atlantic Ocean overturning circulation. The heating of the global ocean has been going on at a steady rate of nine zeta Joules per year for decades , which is 15 times the worldwide primary energy consumption.
In 2019, over 200 environmental activists were killed, according to data from the advocacy group Global Witness. The Global Witness data found that 40 percent of all victims in 2019 were Indigenous, and more than a third of the attacks between 2015 and 2019 targeted Indigenous peoples. ———. Consider this chain of events.
Accompanied by artists’ impressions of volcanic landscapes or storms raging above shimmering oceans, such work makes distant planets feel somehow more real. One is transmission spectroscopy, which looks at the spectrum of starlight that has passed through an exoplanet’s atmosphere. Transmission spectroscopy is limited too.
First, underwater – in the sediments on the bottom of swamps, lakes, and the ocean. OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster.
Hatcheries like the Carson National Fish Hatchery, pictured here, breed millions of salmon and let them grow until they are mature enough to be released so they can try to swim to the ocean. Nearly 250 million young salmon, most of them from hatcheries, head to the ocean each year — roughly three times as many as before any dams were built.
from 1990–2019. Concentrations of CO2 in the atmosphere have risen approximately 47 percent since 1750, mostly from the burning of fossil fuels for energy. Strategies for capturing carbon from fossil fuel power plants, to prevent it from entering the atmosphere, have long lingered on the sidelines. Pennsylvania is banking on it.
Pictures before and after a debris flow event in Colombia between 2018 and 2019. Here, flooding isnt just a threat, its part of the natural cycle, one that now coexists with increasingly intense hurricane seasons driven by a warming atmosphere and ocean. Can you recognize the common locations in the photographs?
For Urban Ocean and the cities they partner with, it is just the beginning. Many cities around the world struggle to create systems to manage their waste, and that can sometimes mean that trash ends up as pollution in our ocean. Thanks for signing up for Ocean Conservancy emails. Please try again or contact 1.888.780.6763.
In the basic physics of climate change, a warmer atmosphere holds more moisture, resulting in heavier downpours, a core ingredient of these events. Research carried out by Climate Central found that climate change increased the intensity of most Atlantic Hurricanes between 2019 and 2023.
National Oceanic and Atmospheric Administration’s (NOAA) annual Lake Erie harmful algal bloom (HAB) forecast shows not enough is being done to save the lake. The Canada-Ontario Lake Erie Action Plan was announced in 2018, but there hasn’t been a progress update since 2019. Algal blooms happen when algae grows out of control.
