Last month, 44 climatescientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. Picture Quebec City in Canada and London in the UK.
Sealevels are rising, and science shows they will continue to rise for generations due to heat-trapping emissions that have already been released. This highlights a profound and enduring climate injustice: future generations will face the consequences of todays decisions. What do we know about future sealevel rise?
The rapid meltdown of polar ice could shut down a key ocean current by 2050, triggering catastrophic surges of sealevel rise along the U.S. East Coast and dangerous climate shifts in northwestern Europe.
It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. The Keeling curve, highlighted with the release of important climate reports and climate summits.
Through greenwashing ads, disinformation campaigns, attacks on scientists, and production of fake scientific evidence, the industry has engaged the playbook of deception to undermine climate action. UCS’s new Hitz Family Climate fellow, Dr. Shaina Sadai , is stepping into this emerging area of work.
Climate models and climate impact studies use emission scenariosestimates of potential future changes in heat-trapping emissionsto help us see how choices made about emissions today can shape tomorrows climate. One of the primary applications of IPCC scenarios is in global climate modeling.
As climatescientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Figure SPM 8.
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. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
Presumably Dagsvik and Moen are used to this kind of model, but they seem to be inexperienced with the models used for weather and climate, which on the other hand are based on the laws of physics. The global sealevel acts like the mercury in a thermometer because warmer water expands.
Corporate leadership was informed about advances in climate science and incorporated those advances when its scientists built their own models. Regardless, the company publicly cast doubt on the reality of global warming, attempted to discredit climatescientists and climate models, and tried to block climate action.
1 – People and places are struggling with wildfire As a climatescientist living in California and witnessing the consequences of decades of unchecked climate change, my personal and professional lives often overlap. Last summer, my family and I went on a long, winding road trip through California and Oregon.
The first climate change presentation I saw was back in the 1970s when I was working for the National Weather Service. Murray Mitchell, was the top climatescientist for NWS. While that got the bulk of the publicity, Dr. Mitchell assured us that the warming of the climate would be the biggest problem in the future.
In addition, it stores vast quantities of freshwater that if released to the ocean would rise sealevel 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.
For climatescientists, the war in Ukraine came at the worst possible time as the media attention they would have hoped for surrounding the release of the latest Intergovernmental Panel on Climate Change (IPCC) report was urgently diverted to the breaking news story of Russia invading Ukraine. By Anders Lorenzen.
Since that 2014 study, which laid the foundation of what is called climate source attribution science , UCS scientists have collaborated with Heede on two other studies that pinpointed the major carbon producers’ culpability for specific climate change-related trends. Licker et al.
Climatescientists at the Union of Concerned Scientists (UCS) have dubbed the six-month stretch from May through October the “ Danger Season.” Not only has much of what climatescientists have been warning about come to pass, many of the extreme weather events the planet is now experiencing are worse than they expected. “To
Some of the highest risks can be found in the candidates’ home states: the ocean off of Florida has hit 98 degrees— hot tub temp s! Among mid-Atlantic states, New Jersey is ground zero for climate change. We should expect to hear more, as climate impacts are only going to get worse.
Court Dismissed Counterclaims in ClimateScientist’s Defamation Lawsuit. Superior Court dismissed counterclaims brought by an individual writer against the climatescientist Michael Mann in Mann’s defamation lawsuit against National Review, the Competitive Enterprise Institute, and two individuals. California v.
It makes them ripe for disproportional impacts from climate change, relative to the nation in general. The 2020 study offered an exclamation point: “Without emissions reductions, climate change could increase temperatures across the national parks, up to 9ºC (16ºF) by 2100 in parks in Alaska.
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.
Extreme climate-related disastersincluding heatwaves, storms, droughts, wildfires and floodingare worsening, taking a fearsome toll on people, the economy and ecosystems. Accelerating sealevel rise, ocean acidification and loss of major ice sheets also continue apace, with profound consequences for the planet.
Bernhardt’s reasoning was that it would be impossible to establish the requisite causal link between GHG emissions, global climate change, and specific localized effects on species and their habitat due to the “complex and independent processes active in the atmosphere and the ocean acting on GHGs.”
Extreme climate-related disastersincluding heatwaves, storms, droughts, wildfires and floodingare worsening, taking a fearsome toll on people, the economy and ecosystems. Accelerating sealevel rise, ocean acidification and loss of major ice sheets also continue apace, with profound consequences for the planet.
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). Arizona Court Ordered Production of ClimateScientists’ Emails Under Arizona’s Public Records Law.
A federal district court in the District of Columbia ruled that the Bureau of Ocean Energy Management (BOEM) fulfilled its obligations under NEPA in connection with two offshore oil and gas lease sales in the Gulf of Mexico. Federal Court Rejected NEPA Claims in Challenge to Gulf of Mexico Leases. Delta Stewardship Council Cases , Nos.
It needs to be an informed decision with equal input from climatescientists and economists. Report after report, scientist after scientist, they continue to demonstrate that our lack of movement on climate change is leading to stronger and more frequent and dangerous weather patterns and rising ocean waters.
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. Sarah Kapnick as the agency’s chief scientist. in atmospheric and oceanic science from the University of California, Los Angeles. 13, 2022).
How much will global temperatures and sealevels rise, when will that occur, and exactly what effects they will have all are uncertain. º C, viewed by climatescientists as a critical threshold to avoid catastrophic impacts. The SCC then monetizes those impacts over time.
The full Senate also confirmed Monica Medina to be assistant secretary of state for oceans and international environmental and scientific affairs by a 61-36 vote. During her confirmation hearing, Medina pledged to prioritize addressing biodiversity loss, ocean protection and space policy. Proposals must be received via email by 5 p.m.
A few general resources: Sidelining Science Since Day One: How the Trump administration has harmed public health and safety in its first six months by The Union of Concerned Scientists I Heart ClimateScientists. . pulling out of the Paris climate deal may make China great again. And now the full list: . 2017.06.01.
