I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on ClimateChange (IPCC) on August 9th. The cause of our changingclimate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
A new paper by Ben Santer and colleagues has appeared in PNAS where they extend their previous work on the detection and attribution of anthropogenic climatechange to include the upper stratosphere, using observations from the Stratospheric Sounding Units (SSUs) (and their successors, the AMSU instruments) that have flown since 1979.
Last week, Senators Schumer and Manchin announced a compromise on a reconciliation bill, called the Inflation Reduction Act of 2022 , that includes significant climate and air quality progress and a goal to reduce greenhouse gas emissions nationwide by 40 percent by 2030. A key step towards addressing climatechange and air quality.
Global net anthropogenic greenhouse gas emissions 1990–2019. Global net anthropogenic greenhouse gas emissions include carbon dioxide from fossil fuel combustion and industrial processes, net carbon dioxide from land use, land use change and forestry, methane, nitrous oxide, and fluorinated gases. billion on advertising.
Today, climatechange is the central, though by no means the only, concern in environmental law. Westlaw searches for “global warming” and “greenhouse effect” pick up only a handful of citations before 1985. I found only one relevant reference using the term “climatechange” before 1985.
As COP26 gets underway this week in Glasgow, Scotland and the World Meteorological Association warns that the past seven years are set to be the warmest on record, we thought this the right time to explore the associated impacts of climatechange on the air we breathe. As average temperatures rise, ozone levels accelerate.
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. See, Weather.
By Phil McKenna Emissions of a small group of chlorofluorocarbons (CFCs), man-made chemicals that destroy Earth’s protective ozone layer and fuel global warming, are back on the rise after their production was all but banned more than a decade ago, a new study concludes.
By Georgina Gustin At its annual conference on climatechange this week, the United Nations released a major report saying the world has little hope of reaching global climate targets without quickly lowering emissions of nitrous oxide, a greenhouse gas that’s nearly 300 times more powerful at warming the atmosphere than carbon dioxide.
No serious person is advocating for any large-scale deployment of solar geoengineering or substituting it for other urgent climatechange mitigations, so the shorthand use of “opponent” or “supporter” is itself misleading and pushes voices to extremes. Anyone can float a balloon. Critics believe it is the path to catastrophe.”
The detection and the attribution of climatechange are based on fundamentally different frameworks and shouldn’t be conflated. But there is a fundamental problem here to which I’ll return below. But first, an easy example: Global mean surface temperatures. As in the previous example, it’s not even wrong.
Climate researchers are learning that warming temperatures and heat waves resulting from greenhouse gas (GHG) emissions could adversely affect air quality in the United States and increase deaths from air pollution exposure. This effect is referred to as the “climate penalty.” Read the full story from U.S.
Costly and Inequitable In addition to emitting greenhouse gases, gas power plants also pollute the air with nitrogen oxides, sulfur dioxide, particulate matter, and volatile organic compounds.
Both of these issues stem from the realization that climatechange is no longer purely a long-term issue for which an assessment updated every decade is sufficient. The End of History A big part of the effort to both understand past climate and project future climate is supported by the CMIP program. Gettelman, and A.
Medium- and heavy-duty vehicles (MHDVs), like the big rigs on our highways and the vans that deliver our packages, make up just over 1 in 10 of the vehicles on our roads, but are responsible for over half of ozone-forming nitrogen oxide pollution and lung-damaging fine particulate pollution from on-road vehicles.
In the last few months he has given two interviews in which he goes into to detail about what he describes as a ‘missing element’ in climate science and what he imagines the consequences are for climatechange. Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!)
For example, EPA rules limiting ozone pollution or carbon from power plants move the first lever, while the combined $1.25 Throughout this year, EPA has heard from numerous stakeholders at many forums and made these interesting changes to the design. Details on eligible applicants and coalitions for this section are available here.
And to zoom out a bit, burning fossil fuels is the primary contributor to global climatechange, which is driving and exacerbating the once-rare extreme weather events that are impacting people across every part of the country—and across the world. It must not respond by watering the protections down based on industry disinformation.
The de riguer environmental imperative of responding to the immediate threat of global warming through reducing greenhouse gas emissions, to the detriment of other environmental impacts, is simply taking one environmental impact too far. This is not my perspective alone.
Trucks and buses on California’s roads and highways are responsible for the majority of lung-damaging fine particulate and ozone-forming nitrogen oxide emissions, and a sizable amount of climate-warming greenhouse gas emissions as well.
In this blog post, we will explore why targeting methane emissions presents a more advantageous strategy for the United States in its quest to mitigate climatechange. Co Benefits for Human Health : Methane is a key precursor of tropospheric ozone (ground level), a harmful air pollutant.
States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S.
Plug gaps to measure ozone-destroying chemicals and greenhouse gases and verify compliance with Paris and Montreal treaties. Read the full story at Nature. Read more →
The CPDW is thought to be affected by the shift in the westerly winds around Antarctica which have increased in recent decades due to a combination of greenhouse gas forcing and the polar ozone hole ( Miller et al, 2006 ). 2020) or Sadai et al. References. Miller, G.A. Schmidt, and D.T. Marshall, M. Russell, L.S. Nazarenko, Y.
While the movie might seem pessimistic to many, our hope is that climate tech innovation and rising awareness will assist us all in the creation of a positive, safe and healthy future. ClimateChange is No Laughing Matter. But it’s up to all of us to act. By the 2040s, wildfire numbers could increase by 32% and burn area by 33%.
million commercial trucks on California roads, and although they make up just seven percent of vehicles on the road, these trucks are responsible for more than one-quarter of greenhouse gas (GHG) emissions, more than 60 percent of smog-forming nitrogen oxides (NOx) and more than 55 percent of lung- and heart-harming fine particulate (PM2.5)
China is intent on using the Winter Olympics to showcase how they’re at the forefront of implementing low-carbon technologies and thereby tackling climatechange. This is replacing the traditional hydrofluorocarbons which have been found to damage the ozone layer. Photo credit: Beijing 2022. By Anders Lorenzen.
The Advanced Clean Fleets (ACF) rule has the potential to significantly reduce climate-warming greenhouse gas (GHG) emissions as well as harmful air pollutants like fine particulates (PM2.5) This new regulation would apply to delivery vans, big rigs, box trucks, and buses.
The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. The SCAQMD is the local agency responsible for attaining these clean air standards in the Basin. Facility-Based Mobile Source Measures.
million in Alternative Fuel Incentive Grants (AFIGs) to 18 cleaner fuel transportation projects statewide that will reduce greenhouse gas emissions and other air pollutants. Transportation generates 47 percent of nitrogen oxide emissions in Pennsylvania, contributing to the formation of ground-level ozone.
. -- Air pollutant reductions and human-health improvements – the DEP Electric Vehicle Roadmap indicates that a number of Pennsylvania counties consistently exceed EPA human-health standards for ozone and fine-particulate matter. The burning of transportation fuels, such as gasoline and diesel, is a substantial source of air pollution.
This funding builds on Governor Shapiro’s agenda to create a bold, comprehensive climate and energy plan that will grow Pennsylvania’s economy, protect and create jobs, and address climatechange. It also helps lower the level of carbon dioxide, one of the greenhouse gases heating up the climate, in the air.
The House Environmental Resources and Energy Committee is scheduled to hold a hearing May 1 on cryptocurrency and climatechange. At the hearing, Robert Altenburg, PennFuture’s Senior Director for Energy and Climate presented an overview of cryptocurrency mining in Pennsylvania and its environmental impacts.
Summary: Green-roof zoning laws may provide a solution to the Urban Heat Island Effect, which contributes to anthropogenic climatechange through heat pollution originating from large cities. Green-roofs are an overlooked solution to the complex problem of heat pollution, which contributes to anthropogenic climatechange.
For many, this problem is writ large in the climate context. On one view, this might seem to set the stage for the exacerbation of a fragmented international legal response, ‘undermining the foundations of future cooperation combating climatechange’.
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. Maritime shipping must do its part to tackle climatechange. as a national policy leader.
Shapiro’s agenda to create a bold, comprehensive climate and energy plan that will grow Pennsylvania’s economy, protect and create jobs, and address climatechange. It also helps lower the level of carbon dioxide, helping to address climatechange. It builds on Gov. The deadline is December 15.
In addition to the 22 percent passenger and light duty vehicle requirement, the proposed regulation will also add a greenhouse gas fleet average requirement for Pennsylvania sales. There is no ban on traditional internal combustion engine vehicles.
Hydrofluorocarbons (HFCs) were developed and introduced in the late 1980s to serve as replacements for ozone-depleting substances (ODS) primarily used in the air conditioning, refrigeration, aerosols, fire suppression, and foam blowing industries.
The past two years have yielded unprecedented executive and regulatory engagement in the climatechange discussion. international climatechange agreement. to help reduce greenhouse gas emissions. Furthermore, the specific effects of carbon emissions on global climatechange are also. free market.
Transportation is the largest source of greenhouse gas emissions in California. In order to achieve the state’s goals of carbon neutrality by 2045 and avoid the worst impacts of climatechange, decarbonizing this sector is essential. Health: Transportation is a major cause of local air pollution, as well as climatechange.
Each month, Arnold & Porter Kaye Scholer LLP (APKS) and the Sabin Center for ClimateChange Law collect and summarize developments in climate-related litigation, which we also add to our U.S. climate litigation charts. and non-U.S. The magistrate judge’s order also set the trial to begin on February 5, 2018.
Mitigation – deep rapid cuts to worldwide emissions – is the first, essential element of effective climate response. I don’t think there’s anyone thinking seriously about climatechange who disagrees with this. First, what the Earth system sees and what actually matters for climatechange is net emissions.
True, methane is a potent greenhouse gas. Because methane contributes to ozone pollution, emissions cause immediate health effects as well as warming effects. Before we can take those steps, institutions and public attitudes will themselves have to adapt to the realities of climatechange. According to the U.N., “a
