A new study reaffirming that global climatechange is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather. Read more on E360 →
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.
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.
Warming of the surface of the Arctic is matched by a colder polar vortex high in the atmosphere, which is speeding the breakdown of the Earth’s shield against ultraviolet rays.
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.
The American Lung Association’s State of the Air report measures three of the major types of pollutants in the San Joaquin Valley: long-term particle matter, short-term particle matter, and ozone. Ozone, too, poses significant risks to respiratory health. Ozone plays a dual role in our atmosphere.
Today, climatechange is the central, though by no means the only, concern in environmental law. I found only one relevant reference using the term “climatechange” before 1985. In one sentence of a 1975 article, John Barton referred to “climatechange” as a potentially severe long-term problem.
A new study reaffirming that global climatechange is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather. Read the full story from e360.
As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century, a new MIT study predicts. The world’s oceans are a vast repository... The post Oceans may start emitting ozone-depleting CFCs appeared first on successful GREEN.
Readers will recall that the TLT product is nominally a weighted average of atmospheric temperature anomalies from the surface up to 5km or so. The upward trends differ slightly for sure, but they are all recognizably describing the same climatechange. As I understand it (and someone correct me if I’m wrong!), Hao, and Q.
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 (!!)
Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.
The expansion of industrial-scale farming in the basin, plus rainstorms made worse by climatechange, have caused the blooms to surge in recent years. Climatechange promises to raise all of these costs. Climatechange events, and its related impact on nutrient runoff, are not fair in their impacts.
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. Over a 20 year period, methane is estimated to be more than 80 times as potent as carbon dioxide in terms of trapping heat in the atmosphere.
Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone.
In the 1960s climatechange was not really a significant concern, not even amongst environmentalists – this was despite the fact that the Swedish scientist Svante Arrhenius in 1896 was the first to claim that emissions from fossil fuels might eventually result in enhanced global warming. This has since changed many times.
Recent science doesn’t support this optimism, as new studies show that the increased release of Black Carbon, one of the most potent climatechange forcers—as well as soot, carbon dioxide, methane and ozone from more traffic in the Arctic—could lead to a 20% increase in the global heating that is causing warmer ocean temperatures.
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’.
Climatechange is making asthma worse, as hotter temperatures increase ozone pollution and wildfires and make pollen season longer. But asthma, ironically, is also making climatechange worse: Inhalers use chemicals that are as much as 3,600 times more powerful than CO2 at trapping heat in the atmosphere.
The boundaries range from climatechange to the biosphere and deforestation , and from pollutants & plastic to nitrogen cycles and freshwater. The boundary for ozone depletion, for example, while not transgressed globally, was headed for increasing regional transgressions. C planetary climate boundary.
Transportation generates 47 percent of nitrogen oxide emissions in Pennsylvania, contributing to the formation of ground-level ozone. Vehicles alone release 21 percent of carbon dioxide emissions in the state, a known greenhouse gas and direct contributor to climatechange.
GHG Emissions by Sector Climatechanges pollution and pollution changesclimate Another reason to look at the global warming impacts of refineries from a health perspective is that there is an important link between global warming and local pollution. which is formed in the atmosphere from precursor gases such as NOx.
The plan cuts power plant and industrial ozone pollution that wafts from central parts of the nation into eastern states. According to the American Lung Association, nearly 120 million people in the nation—one of every three—lives with unhealthy levels of particle and ozone pollution. A 40-year-old Supreme Court ruling (Chevron v.
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.
But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. Because methane contributes to ozone pollution, emissions cause immediate health effects as well as warming effects. The carbon from those wildfires could stay in the atmosphere a long time, causing additional warming.
Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity. Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone.
But since it became clear that human actions are damaging the environment and changing the climate, it has become much more prominent nationally and internationally with most government departments in most countries having responsibilities to mitigate or prepare for climatechange scenario. Oscillations.
Levels of Ground-level Ozone Pollution Can Increase in Summer. As ground-level ozone requires the presence of sunlight to form, high heat and sunny weather can function to increase concentrations of this particular pollutant. Elevated ground-level ozone may also severely reduce crop yields during their primary growing season.
When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,
To determine the exposure of the local population to harmful hydrocarbon and ozone levels. UCAR - The University Corporation for Atmospheric Research is a nonprofit partnership of over 115 colleges and universities in North America conducting Earth system science research and training.
The developing science of climatology with its understanding of the need for chemistry made scientists concerned for the future on seeing masses amounts of carbon released into the atmosphere (8) , but also (as it was previously) regarding trees as a resource and the potential for depletion. Consider an energy policy degree.
And just three years ago, Reviving the Dead Zone provided the first comprehensive assessment of the Gulf of Mexico dead zone’s economic impact, and warned the root problem—agricultural runoff pollution—will likely worsen due to climatechange. But nitrous oxide is even more insidiously efficient at disrupting the climate.
Methane is a potent greenhouse gas 80 times more powerful than carbon dioxide for the first twenty years that it remains in the atmosphere. Methane pollution is also responsible for more than 25 percent of the climatechange Pennsylvania experiences today.
“The United States is once again a global leader in confronting the climate crisis, and we must lead by example when it comes to tackling methane pollution – one of the biggest drivers of climatechange. can take in the short term to slow the rate of climatechange.
This, along with many other chemicals, like diesel particulates and ground-level ozone that form soot and smog, and metals like lead in paint and drinking water, are regulated by the EPA to keep us safe. PFAS is shorthand for a class of “forever chemicals” that persist in the environment indefinitely.
The emissions make a significant contribution to climatechange because methane is a highly potent greenhouse gas which, in the first 20 years after it is released, traps approximately 84 times more heat in the earth’s atmosphere than carbon dioxide (on a per ton basis). and our citizens.”.
Each month, Arnold & Porter 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. HERE ARE THE ADDITIONS TO THE CLIMATE CASE CHART SINCE UPDATE # 133. By Margaret Barry and Hillary Aidun.
Proposals for geoengineering — reducing warming after carbon emissions are already in the atmosphere — range from being almost literally garden variety to the realm of science fiction. loss of stratospheric ozone); important aspects of regional climate (e.g.,
Attorneys general (AGs) in the five states most vulnerable to climatechange, however, are doing the exact opposite: Instead of defending their constituents, they are defending the fossil fuel industry. By railing against what he calls a “radical climatechange movement” and suing the federal government to protect corporate polluters.
Legislators provide $200 million to NOAA for weather, coasts, oceans and climate research, $100 million for NOAA competitive climate research grants and provides $100 million to NOAA for development and dissemination of climate science information products and services. degrees Celsius. Biden EPA move to repeal Trump WOTUS rule.
report on how world can still stop climatechange. report on how world can still stop climatechange. BRUSSELS — The world can avoid the worst consequences of climatechange, but emissions need to peak by 2025, the U.N.’s s climate science panel said in a major new report on Monday. “We
Nobel Prize recipients urge G7 leaders to take transformative action to address climatechange. Part two , scheduled for a November proposal, will make “broader changes,” according to the agenda. Julia Brownley (D-CA) reintroduced the Marine Mammal ClimateChange Protection Act ( H.R. International. 1816 & H.R.
The SCC is a metric that seeks to capture all of the costs that emitting a ton of carbon dioxide (or equivalent amounts of other greenhouse gases such as methane) imposes on society by contributing to climatechange over the hundreds of years it remains in the atmosphere. What Are the Key Variables Affecting the SCC Amount?
