Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. This has been noted as a source of climate injustice , due to the profound impacts on future generations and low-lying coastal communities.
You might be thinking, if the burning of fossil fuels increases Earths albedo due to additional aerosols in the atmosphere, shouldnt this offset any impact from the effects of increased heat-trapping emissions like carbondioxide?
It shows the atmospheric concentrations of carbondioxide (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.
With the United Nations Climate Change Conference (COP26) coming up next month, it is strange to think that less than 100 years ago global warming was not widely accepted, even among experts. Callendar’s 1938 paper “The artificial production of carbondioxide and its influence on temperature” ( Q. 139 1961 ).
In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climatescientists. Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993).
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.
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. But what exactly would cause the AMOC to collapse?
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.
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. Johnson, A.
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. For the first piece, there needs to be a well-designed, justice-centered plan to reduce heat-trapping emissions.
This is the third year in a row that emissions from energy are flat, yet, climatescientists report that our atmosphere is seeing its carbon content grow faster than ever. The biggest drop came from the United States, where carbondioxide emissions fell 3%, or 160 million tonnes, while the economy grew by 1.6%.
The El Niño–Southern Oscillation ( ENSO ) is one of the most significant, but variable, climate patterns in the world. This tropical Pacific Ocean phenomenon affects weather in South America, Australia, Asia, and beyond. Researchers are also studying how ENSO will be affected by climate change.
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. percent of total emissions. Licker et al.
Each storm made history in its own right: Beryl was the earliest Category 5 storm on record in the Atlantic Ocean, Helene broke rainfall records in Georgia, North Carolina, South Carolina, and Tennessee, and destroyed tens of mountain communities, and Milton was the second fastest intensifying storm since 1979.
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. Bernhardt , No.
In videos and Congressional testimony , Wright portrays himself as a truth teller, while falsely claiming that climatescientists and renewable energy advocates are deceptive. In the last sixty years, the amount of carbondioxide in the atmosphere has grown 100 times faster than it did at the close of the last ice age.
BLM estimates that the project will produce up to 576 million barrels of oil over its 30-year lifetime, resulting in indirect emissions totaling 239 million metric tons of carbondioxide (CO 2 ) equivalent. There are many other pathways through which climate change can affect these species (e.g.,
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.
And in summary, his testimony says, one, joining RGGI will reduce emissions of carbondioxide from Pennsylvania's power generation sector and will also contribute to improved air quality. It needs to be an informed decision with equal input from climatescientists and economists.
Capturing carbon is a must. Countries will also have to extract carbondioxide from the atmosphere to keep global warming in check. Some of those techniques would allow the extended use of fossil fuels, which is why they are backed by industry and extracting countries, but the idea is strongly opposed by climate campaigners.
The SCC is a metric that seeks to capture all of the costs that emitting a ton of carbondioxide (or equivalent amounts of other greenhouse gases such as methane) imposes on society by contributing to climate change over the hundreds of years it remains in the atmosphere.
