New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information. New studies are being published and commissioned and research gaps are being identified.
Why it matters: The recent Inflation Reduction Act expands the tax credit for capturing carbon dioxide that would otherwise be released into the atmosphere. The post FRESH, October 4, 2022: Carbon Dioxide Storage and Transport Emerges as Political Flashpoint appeared first on Circle of Blue.
Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100. Radiative forcing is the change in energy balance in the Earths atmosphere due to heat trapping emissions. Studies show that high-emission scenarios like SSP5-8.5
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.
A year of financial and political crises have left Pakistan’s economy on a knife-edge. Pakistan, which is already facing political and economic turmoil, has been thrown into the front line of the human-induced climate crisis,” a U.N. statement read earlier this week. .
Such events are becoming more common as Earth’s atmosphere continues to warm. Rehman urged political leaders to act on the issue, advocating for technology upgrades, ecosystem restoration in the Indus River Valley, and enforcing a 1991 accord that governs the distribution of water between Pakistan’s provinces.
(The “for one year” part is crucial: stratospheric aerosols stay in the atmosphere roughly a year, so one gram offsets the heating effect of one ton only for the first year after the ton is emitted. After that, the sulfur is gone but the CO 2 is still there and heating.)
Forever is only a bit of an overstatement: NASA says CO2 stays in the atmosphere three hundred to a thousand years. If we wait to get the stronger policy, we’re accumulating emissions that will stay in the atmosphere for centuries — in other words, doing permanent damage to the climate.
A thirsty atmosphere evaporates or sublimates its share. With increasing temperatures, “we’re seeing places that do have drought, the intensification is more rapid,” says Roger Pulwarty, a senior scientist in the physical sciences laboratory at the National Oceanic and Atmospheric Administration. 4) Drought Is Political.
In the long run, warming will be determined by how much carbon we pump into the atmosphere before we stop. If we can shave down the curve even a little, we reduce the ultimate tonnage of carbon lingering in the atmosphere. The answer is unequivocally “yes.”. In terms of emissions cuts, the basic rule is simple: Every ton counts.
Although atmospheric warming has made severe droughts and heat waves more likely worldwide, the report found that the recent dry spell in Madagascar falls within the natural fluctuations of the country’s weather, which is highly variable. Instead, the biggest factors contributing to widespread hunger are political and economic.
Commissioners bring experience, stature, broad global representation — but crucially, are not presently in political office, so they are not required to advance national positions. They can speak and discuss freely. Getting better, but not very comforting. Current and coming advances in carbon-free technology will help, of course.
Although methane doesn’t linger very long in the atmosphere, increasing methane levels are particularly bad news because it packs a big punch. But its short lifetime in the atmosphere is also a reason for hope. It is 80 times stronger than carbon dioxide (CO2) at trapping heat on short timescales. The planet has already warmed 1.1
China is responsible for about 11% of all the carbon now in the atmosphere, so that would mean paying for that percentage of damage from extreme events caused by climate change. The argument here is that there’s a limit to the total amount of carbon humanity can put into the atmosphere without triggering dangerous climate change.
The latest data from the National Oceanic and Atmospheric Administration ( NOAA ) and the EU’s Copernicus climate service show that the 2024 January-August period is the hottest ever by far, putting this year well on track to be the warmest ever on record. For the next round of NDCs, the U.S.
Burning fossil fuels, cutting down forests, raising livestock, making cement, and using synthetic fertilizers are among the actions that have increased the amount of heat-trapping gases in the atmosphere to the point that the planet’s basic functions are coming undone. The same factors apply to adaptation, especially to water.
of the observed rise in atmospheric carbon dioxide and 52 percent of the rise in global average temperatures between 1880 and 2015. degrees goal is threatened by political inaction. degrees C is scientifically possible; the reason the world might blow past it is political. Why not just start with renewables?
An energetic, bustling atmosphere was partly the point. The conference, however, was constrained by an agreement that no political declaration would be made. That includes a plan to find $30 billion a year for water investment in Africa and a goal to restore 300,000 kilometers of rivers by 2030. Will these initiatives bear fruit?
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.”
It turns out — I’ll bet even most AIs don’t know this — the oxidized carbon byproduct of our fuels has a nasty tendency to pile up in the atmosphere. Even more surprisingly, that changes the atmosphere’s radiation profile. The politics are almost as unstable as the climate system.
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.
But the effect of greenhouse gases is not even investigated in the paper – which suggests the title is politically motivated. Is it sheer incompetence or is it politically motivated? Ed Hawkins, National Centre for Atmospheric Science. Let’s hope it was not political on the part of that institution, but just a bad mistake.
Award-winning atmospheric scientist Katharine Hayhoe will discuss how to build hope in the face of the devastating impacts of climate change during a special event at Dickinson College in Carlisle, Cumberland County. Her talk will take place Wednesday, Dec. 4, at 7 p.m. in the college’s Anita Tuvin Schlechter Auditorium.
The petitioners who brought this case include state-level political officials and coal companies who are single-mindedly determined to block climate action and perpetuate fossil fuel dependence to serve their narrow political or business interests. There is no time to waste.
Katharine Hayhoe, an atmospheric scientist and evangelical Christian, has written a book that lays out strategies for discussing the climate crisis in a divided country. Read the full story in the New Yorker. Read more →
It stressed the need to reduce the release of heat-trapping gases into the atmosphere, and to limit global warming to 1.5 As Henk Ovink, the Netherlands’ special envoy for international water, put it, “The moment you want to bring water to a political table, there is no political table.”. degrees Celsius.
The political dimension is a huge part of the solution to the water crisis,” said Federico Properzi, chief technical adviser of UN-Water. He said that game changers will be those supported by money or political power, or those that can be applied at scale, across multiple areas.
The US National Oceanic and Atmospheric Administration says it is discontinuing its regular update calls due to staffing problems, but its researchers may also fear political retaliation for discussing climate change
I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. It’s a fascinating story of technology, creativity, hubris, error, imagination, rivalry, politics, and (for some) a search for scientific consilience – worthy of movie script perhaps?
If governments bypass or undermine science and public comments in policy making, our health could be in jeopardy from increased pollution, cases of foodborne illnesses, politically-driven medicine approvals or disapprovals, and more. It was not a catchy slogan to write on a cardboard sign, but the message is important to all of our lives.
Unsafe Yield – Severe drought, dead well, and political division push Arizona steadily closer to water supply peril. According to the latest forecast from the National Oceanic and Atmospheric Administration (NOAA), drought will continue in more than half of the continental United States through at least the beginning of summer.
Climate models predict with near unanimity that more atmospheric warming will increase annual rainfall in Michigan and Ohio: a trend that is already making algae blooms worse. And political power with it. Just lack of political capital. Climate change promises to raise all of these costs. Carl Ganter/ Circle of Blue.
A recent atmospheric river in British Columbia leaves nearly 20,000 people stranded and thousands of animals dead. HotSpots H2O: In Afghanistan, Political Upheaval Aggravates Drought-Fueled Famine – Well before Afghanistan’s political upheaval this summer, drought was pushing the country to the brink of a food crisis.
There are even indications that near-term cuts might be easier to achieve for methane than for CO 2 , for a mix of technical, economic, and political reasons. Atmospheric concentrations. That small concentration of methane in the atmosphere makes an outsized contribution to global heating. Climate impact.
The issue has begun changing minds about climate change among recreational fishermen, a demographic that leans politically conservative. As the atmosphere continues to warm, severe weather events have gone from occasionally urgent to relentless assault. . The root cause of the issue is global climate change.
By Phil McKenna and Peter Aldhous Preliminary atmospheric monitoring data from a remote South Korean island off China’s east coast shows elevated concentrations of hydrofluorocarbon-23 (HFC-23), a greenhouse gas 14,700 times more potent than carbon dioxide on a pound-for-pound basis, according to the World Meteorological Association.
Management approved her shift in emphasis, hoping that she would prove that aerosols in the atmosphere (including those from auto exhaust) would completely offset the greenhouse gas effect. She met a visiting physicist from Princeton on her very first week on the job. He talked her into studying climate change.
Methane has a comparatively short life in the atmosphere (about 12 years, as opposed to 100 years or more for CO2) and high potency (84 times stronger than CO2, averaged over 20 years). Right now, oil companies have political power sufficient to preclude a change in liability that would result in oil industry obligation.
They are slow to begin but can last indefinitely, some “megadroughts” upending social and political stability over several decades. Specialists like Pulwarty, who is currently a senior scientist in the physical sciences laboratory at the National Oceanic and Atmospheric Administration, use the word “cascade” to describe the long reach.
The WMO’s GHG bulletin’s headline takeaways are stark: Atmospheric concentrations of three major heat-trapping gases, carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) hit all-time highs in 2021 (see table below). Source: UNEP 2022 Emissions Gap Report. The World Meteorological Organization Greenhouse Gas Bulletin.
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. But climate litigation is an important step in holding the fossil fuel industry accountable for its role in the crisis and determining who should pay.
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.
