If you live in a coastal zone and have looked at maps of future sealevel rise or have read about how climate change could be slowed with policy changes to reduce emissions, youve likely seen these scenarios in action. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.
An expert on sealevel dynamics and climate justice within the UN negotiations, Dr. Sadai is working to ensure that her scientific studies get in the hands of decisionmakers who are shaping our world today. UCS’s new Hitz Family Climate fellow, Dr. Shaina Sadai , is stepping into this emerging area of work.
What are the political implications of the fact that climate change will continue after emissions cease, or even potentially grow worse? First, after carbon dioxide emissions cease, atmospheric carbon dioxide levels begin to decrease, as they are absorbed by natural processes and sinks in the oceans and on land. degrees Celsius.
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.
By Bob Berwyn At the current level of human-caused global warming, extreme rainfall from atmospheric rivers, as well as an extensive network of previously undetected micro-cracks, could degrade large parts of the Greenland Ice Sheet faster than expected and accelerate melting toward worst-case projections for ice loss and sealevel rise, recent research (..)
In particular, he said, “reliance upon coal, on the other hand, could aggravate the ‘greenhouse effect,’ whereby excess carbon dioxide (which accompanies coal burning) traps heat inside the earth’s atmosphere, thus possibly melting the icecaps and raising the level of the oceans.”
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. Sealevels are rising. The Gulf of Maine Research Institute climate dashboard clearly indicates sea surface temperature anomalies.
This methodology is similar to my own work combining climate science, political science, and history to reconstruct how UN climate negotiations have played out and what that implies for climate justice. The present is always being created out of past actions that led to where we are today.
In the 1960s, scientists were warning that the burning of fossil fuels was releasing carbon dioxide into the atmosphere, which could have catastrophic consequences for the planet. States and local governments are suing for damages So why are states and local governments suing the fossil fuel industry now? But the tide is turning.
Basically, I go back to my freshman year geopolitics class from college and the professor who really got us thinking about political geography, but the layers of geography. Political geography of borders and so on, in a complex interplay. Then there’s politics, civil wars, conflicts and so forth. To decarbonize industries.
Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO 2 emissions from human activities to ‘net zero’ – where the amount of CO 2 we emit into the atmosphere is equal to the amount we remove from it. At this point, they remain political. To keep within the 1.5°C
Even before adoption of the 1992 Framework Convention, the Alliance of Small Island States (AOSIS) had proposed an “International Insurance Pool” to pay vulnerable countries based on observed sealevel rise. The first explicit use of the term L&D was in the 2007 Bali Action Plan , in a section on enhanced action for adaptation.
Candidate in the Department of Political Science at Colorado State University If we could predict a flooding, drought, or heatwave event one month in advance, how many lives could be spared with more time to prepare? On longer timescales, the ocean connects global patterns through ocean circulation and sealevel pressure.
Satellites, for example, are used in meteorology to track weather systems and to monitor atmospheric fronts to predict what the weather will do next. Known as ENSO, they are opposite effects of the same process and are defined as an oscillation (a variation in magnitude) between the temperature of the atmosphere and the ocean.
The release of carbon dioxide to the atmosphere by the burning of fossil fuels is, conceiveably, the most important environmental issue in the world today. — "Costs and benefits of carbon dioxide," Nature , May 3, 1979. And along with the economic costs will come social and political side effects. The limits of adaptation.
These latest political misadventures by Governor DeSantis are equal parts ostrich-like, head-in-the-sand behavior; straight out of the Flat Earth Society playbook; and reminiscent of Mad Magazine’s/Alfred E. All in an effort to score some cheap political points rather than serve Floridians’ long-term interests and welfare.
Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity. Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmosphericlevels and rise to the upper levels, destroying ozone.
As a climate scientist recently said on CNN, “Until we stop pumping greenhouse gases into the atmosphere we have no idea what the future looks like.” So I’ve begun to meet presidential candidates… … and ask climate questions that relate to their own political history, past statements, and actions.
Doing research on environmental issues or responses is usually an easy call for policy-makers and gets wide political support, even if there’s disagreement what to do about the issue. The way to do this that now looks most promising would be to spray a fine mist of reflective aerosols in the upper atmosphere.
That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.
Lest one thinks this disconnect is a failure of the global climate architecture, the failure lies much closer to home—in the domestic politics in the US and many other countries that continue to favor the interests of the rich and powerful , and fossil fuel companies, at the expense of the health and safety of everyone else and the planet.
A magistrate judge in the federal district court for the District of Oregon granted motions by three trade groups to withdraw from the lawsuit seeking to hold the United States liable for its actions and inaction leading to the accumulation of greenhouse gases in the atmosphere. Exxon Mobil Corp. Schneiderman , No. June 16, 2017).
To meet these goals, the state is facilitating burgeoning carbon capture and sequestration (or storage) (CCS) technologies that capture carbon from point sources to store, as well as carbon dioxide removal (CDR), which removes carbon from the atmosphere. A Few Notable Vetoes.
Anchoring ourselves in a fuller understanding of the web of global politics, special interests, and principled voices that have been shaping the climate movement for over 30 years is a great step, and I recommend this short video to deliver those goods. Babauta of the Northern Mariana Islands; Queen Quet Marquetta L.
Downsize the Office of Oceanic and Atmospheric Research…’ And then it goes on to spread disinformation: ‘OAR is, however, the source of much of NOAA’s climate alarmism. It is not a political document. The preponderance of its climate-change research should be disbanded.’ energy security.’
Earlier in his political career, Bettencourt served as Republican House Majority Leader, and as the public face of the conservative agenda in the state’s House of Representatives. The costs of increased risks from natural hazards—wildfires, floods and sealevel rise— are driving insurers away.
The National Oceanic and Atmospheric Administration (NOAA) is one of the foremost federal science agencies whose foundational work has wide implications and immense value for peoples daily lives and for our economy. We use NWS weather alerts for our Danger Season mapping tool.
Project 2025, the far-rights playbook for systemically reshaping the federal government, specifically calls out the National Oceanic and Atmospheric Administration (NOAA) to be dismantled, downsized, and eliminated. It helps individuals, leaders, and businesses make decisions based on science, not politics, alternative facts, or speculation.
While the pursuit of accountability should consider their role in creating and spreading disinformation and their deception around climate science and research, their contributions of heat-trapping gases to the atmosphere are an important place to start. When visualizing data, clarifying the units used is critical.
At least partly—if not largely—because the AGs and their political organization, the Republican Attorneys General Association (RAGA), receive substantial financial support from fossil fuel companies, electric utilities, and their respective trade groups. Meanwhile, the state has suffered 79 tropical or subtropical cyclones since 2000.
Project 2025, the Heritage Foundations playbook for systemically reshaping the federal government, specifically calls out the National Oceanic and Atmospheric Administration (NOAA) to be dismantled, downsized, and eliminated.
Plaintiffs aim to hold the federal government accountable for worsening the dangers of climate change through increased reliance on fossil fuels and for breach of its fiduciary obligation to protect the atmosphere and oceans under the public trust doctrine.
The plaintiffs alleged that Peabody (and a number of other fossil fuel companies) caused greenhouse gas emissions that resulted in sealevel rise and damage to their property. National Oceanic and Atmospheric Administration , No. Republican National Committee , No. 3:17 -cv-00123 (W.D. Center for Biological Diversity v.
CLF’s allegations included that the landfill’s coastal location “makes it extremely vulnerable to climate change impacts, including sealevel rise and damaging storm surge, creating a significant risk of erosion and of pollution from the Landfill washing into the surrounding rivers and coastal wetlands.” California v. Bernhardt , No.

Several rivers meander through the flat, swampy county and overflow after intense downpours, the kind that are occurring much more frequently as a warmer atmosphere leads to more intense rain events. O’Leary didn’t start out as a flooding expert or a political leader. It’s the very nature of the low-lying landscape.
The next update to the Plan, due in 2022, will outline how the State will reach carbon neutrality by Meeting this target requires immediate actions to reduce GHG emissions and remove carbon from the atmosphere. State Adaptation Strategy.
Congress also found that these processescould contribute to significant global warming, altering world climate patterns and increase global sealevels. For instance, naval bases are generally located at sealevel, and thus structures are at risk from sealevel rise.)
would still result in a rising sealevels, the bleaching of coral reefs, and an increase in heatwaves, droughts, floods, fiercer storms and other forms of extreme weather, but these would be far less than the extremes associated with a rise of 2C. They found a vast difference between the damage done by 1.5C An increase of 1.5C

But in nearly every instance, Rose listened politely, refrained from challenging Tillerson on the facts, and went on to his next question. There is, in fact, substantial scientific evidence that there’s a strong link between global warming and heat waves and coastal flooding from sea-level rise,” I said.
The court stated: “Plaintiffs’ claims for public nuisance, though pled as state-law claims, depend on a global complex of geophysical cause and effect involving all nations of the planet (and the oceans and atmosphere). It necessarily involves the relationships between the United States and all other nations. BP p.l.c. , 18-cv-182 (S.D.N.Y.
Next week, the House is expected to consider another six spending bills, including a bill funding the National Science Foundation and the National Oceanic and Atmospheric Administration. in atmospheric and oceanic science from the University of California, Los Angeles. Comments must be submitted by July 28, 2022. She has a Ph.D.
Labeling these findings as “political” risks concealing climate realities from decision-makers who need accurate, independent science to make informed and accountable decisions. Further, the plan targets the Office of Oceanic and Atmospheric Research (OAR), dismissing it as a source of “climate alarmism” and calling for cuts.
