My top 3 impressions up-front: The sealevel projections for the year 2100 have been adjusted upwards again. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100. And here is the key sea-level graphic from the Summary for Policy Makers: Source: IPCC AR6, Figure SPM.8.
Sealevel rise presents numerous climate justice issues. New research that I led as part of my PhD dissertation, which was just published in Earth’s Future , digs deep into the topic of sealevel rise and climate justice. Climate justice research can help inform these conversations.
Three new papers in the last couple of weeks have each made separate claims about whether sealevel rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. 2020) or Sadai et al.
Antarctica’s melting ice sheet is relieving pressure on the land beneath, allowing it to push upwards in a way that could slow sealevel rise in coming centuries – but only if greenhouse gas emissions are low
Half a dozen takeaways from the report from Gavin SeaLevel Rise in AR6 from Stefan (coming soon) A Tale of Two Hockey Sticks by Mike #NotAllModels discusses the use (and mis-use) of the CMIP6 ensemble by Gavin We are not reaching 1.5ºC earlier than previously thought from guest authors Malte Meinshausen, Zebedee Nicholls and Piers Forster.
Sealevel rise is a big deal Use, abuse and misuse of the CMIP6 ensemble The radiative forcing bar chart has gone full circle Droughts and floods are complicated Don’t mention the hiatus. SeaLevel Rise: The previous IPCC reports, notably AR4 and AR5 (to a lesser extent) , have had a hard time dealing with SLR.
My research looks at issues of climate justice internationally, particularly as they relate to sealevel rise and the Paris Agreement. Sealevels will continue to rise for hundreds of years from just the heat-trapping emissions that are happening today, and once they rise the levels will remain that way for thousands of years.
The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans. mm increase every year.
A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). The global sealevel acts like the mercury in a thermometer because warmer water expands.
By Anders Lorenzen On the eve of the COP28 UN climate summit, The World Meteorological Organization (WMO), a United Nations (UN) body, has warned that the atmospheric concentration of greenhouse gases (GHG) is forecast to continue the trend that resulted in record-high CO2 measurements last year.
C and 2°C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades. Many changes due to past and future greenhouse gas emissions are irreversible for centuries to millennia, especially changes in the ocean, ice sheets and global sealevel.
With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.
Human-driven climate change has set in motion massive ice losses in Greenland that couldn’t be halted even if the world stopped emitting greenhouse gases today, according to a new study published Monday. percent … Continue reading Greenland ice sheet set to raise sealevels by nearly a foot, study finds.
The COP28 climate summit kicked off with a report on the many records broken in 2023, including unprecedented rises in greenhouse gases, global temperatures and sealevel
The latest science shows clearly that the infrastructure in Baltimore will be taxed by sealevel rise, extreme heat, and extended droughts. While weather is always variable, a stable climate helps us safeguard against the devastating impacts of extreme weather events, sea-level rise, and disruptions to essential services.
Similarly, there have been increases in other greenhouse gases , which Gavin nicely describes in his recent post Operationalizing Climate Science. In a nutshell, they are responsible for climate change, mainly due to an increased greenhouse effect.
The radiative forcing over such a long time period needs to take into account the increase in solar irradiance (about 4%) and the impacts of paleo-geography on temperature that aren’t linked to greenhouse gas changes. The first factor increases the apparent sensitivity, and the second decreases it. van der Meer, C.R. Scotese, B.J.
term, even for the very low greenhouse gas emissions scenario.” Using carbon capture, we may be able come back to that level even if we temporarily exceed it. The report points out that under all of the illustrative scenarios it considered, “there is at least a greater than 50% likelihood that global warming will reach or exceed 1.5°
Meltwater from Greenland’s ice sheets have caused about a quarter of the rise in the world’s sealevels. It says that by swiftly and drastically cutting greenhouse gas emissions, the worst effects of climate change can be prevented, avoiding worst-case outcomes for water availability. The report, while grim, does offer hope.
In the run-up to the Copenhagen climate negotiations in 2009, President Mohamed Nasheed held a cabinet meeting in scuba gear 20 feet underwater to show what awaited the low-lying island nation of the Maldives if serious action were not taken to reduce greenhouse gases. I have been in the capital, Male, this week helping lead a U.S.
The world is gathering soon in Glasgow to debate how to eliminate greenhouse gas emissions over the coming decades. But what happens when we achieve the goal of zero carbon dioxide emissions from human actions? Does the climate keep warming, stay the same, or even cool?
Previous IPCC reports have concluded that human activities such as burning fossil fuels are the primary cause of climate change: about 70 percent of global greenhouse gas emissions come from burning fossil fuels for electricity, transportation, and industry. As I prepare myself to read about how the world is inching closer to 1.5
Westlaw searches for “global warming” and “greenhouse effect” pick up only a handful of citations before 1985. The other article about nuclear power also observed in passing that “coal combustion may disrupt global weather patterns by increasing the amount of carbon dioxide in the atmosphere, creating a ‘greenhouse effect.’”.
its district, appellate , and supreme courts decided in favor of Urgenda, an upstart environmental organization, ordering the government to more aggressively reduce greenhouse gas emissions. Environmental Protection Agency (2007) forced the EPA to regulate greenhouse gas emissions. Everyone produces greenhouse gases.
From more and more days of killer heat , to increased flooding and severe storms , to sealevel rise , to ecosystem impacts in the Chesapeake Bay , Maryland has a huge stake in the climate. million metric tons of reduced greenhouse gas emissions through to 2050. This feasible and commonsense regulation would result in 46.45
establishing that heat-trapping emissions (or greenhouse gas emissions) are air pollutants covered by the Clean Air Act. The 2007 case was brought by petitioners (which included several state attorney generals and NGOs, including the Union of Concerned Scientists) in the context of greenhouse gas emissions from new motor vehicles.
Our Environmental Priorities Coalition partner Futurewise has been leading the charge on passing this bill, which promises to provide strong protections for vulnerable communities in the face of climate change, while ensuring we have sustainable solutions in place to reduce our greenhouse gas emissions.

From droughts to wildfires to rising sealevels and torrential rains, the state has felt the effects of a changing climate in a variety of ways. However, there are actions that we can take to address the issue, including reducing greenhouse gas emissions, investing in forest management, and increasing resources for reducing fire risk.
In an opinion by Justice Stevens, the Court held that the threat of sealevel rise gave a state government standing to bring the suit. The Court then held that greenhouse gases are covered by the Clean Air Act as a type of air pollutant. EPA , the Obama Administration issued a series of regulations dealing with greenhouse gases.
But that doesn’t mean the planet returns to its preindustrial climate or that we avoid disruptive effects such as sea-level rise. Today’s models can more explicitly represent the behaviour of greenhouse gases, especially carbon dioxide.
Their annual ‘State of the Global Climate’ report indicated that the accelerating pace of climate change was to blame for acidification and that the melting of ice sheets contributed to pushing sealevel rises to new heights in 2021. The heat trapped by human-induced greenhouse gases will warm the planet for many generations to come.”
As the risks of sea-level rise, stronger tropical storms and seawater intrusion grow due to climate change , Indonesia is ramping up efforts to protect mangrove ecosystems across the archipelago as part of both its COVID-19 recovery efforts and climate change commitments.

As in previous reports, this one also uses “Representative Concentration Pathways” (RCPs) that show how the world will respond to different trajectories for emissions of greenhouse gases. There is greater emphasis on regional impacts and extreme events.
A new study from North Carolina State University shows that methane, a potent greenhouse gas, is largely generated in the soils below standing dead trees in so-called ghost forests, or coastal forests that are being killed off by rising sealevels. Read the full story from North Carolina State University. Read more →
The Advisory Opinion addresses several key questions regarding application of the United Nations Convention on the Law of the Sea (UNCLOS) in the context of climate change, including the interaction between UNCLOS and the global climate change regime, and the specific obligations of States to reduce climate-damaging greenhouse gas (GHG) emissions.
Some of those predicted changes are already happening such as continued sealevel rise which is now irreversible over a time span of hundreds to thousands of years. And by the end of this century, extreme sea-level events which previously occurred every 100 years could happen every year.
They are indeed valuable indicators for the global or regional mean temperature, greenhouse gas concentrations, both ice volume and area, ocean heat, acidification, and the global sealevel.
The Governor approved a notable slate of climate legislation with a package that includes more stringent greenhouse gas (GHG) emission targets and measures designed to reduce the state’s reliance on fossil fuels. Climate Change Mitigation. A Few Notable Vetoes.
Some in the industry see the warming as an opportunity, as passages through the Arctic open for longer periods, even going so far as to claim there will be lower overall greenhouse gas (GHG) emissions from the shorter voyages. Warmer water also expands and raises sealevels as well as holds less oxygen.
In the face of a changing climate, it’s become clear that the GMA also needs to be updated to respond to the climate crisis by addressing our need to rapidly reduce greenhouse gas emissions and building community resilience. Thanks to the collaborative hard work of many, it has been re-introduced as HB 1181 this legislative session.
And on top of that, the UC Berkeley site in Richmond is likely vulnerable to impacts from sealevel rise from climate change. Which begs the real policy question here – if you aren’t going to increase enrollment in UC Berkeley, where would you do it?
Student in the Department of Civil & Environmental Engineering at Colorado State University The Challenge of SeaLevel Rise Imagine your favorite beach town slowly disappearing beneath encroaching waves. Rising sealevels, a consequence of climate change, pose a significant threat to coastal communities worldwide.
Rising sealevels and increased intensity of storm surges are playing a considerable role in the degradation of coastal regions in the Pacific Islands. Illustrating the variation in sealevels from 1993 – 2018. Ideally, the best way to save these islands is to reduce our greenhouse gas emissions. should be.
