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.
Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).
So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. You might recall that GWP is defined as the ratio on per-kg basis of the temperature impact of other greenhouse gases compared to CO 2 over a specific time period.
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.
As deeply troubling reports continue to come in about ocean waters hitting historic hot temperatures, sectors like global shipping are trying to understand the consequences of a warmer ocean and what can be done to stop the heating. So, we’re seeing the ocean heat up, lose oxygen and get bigger.
Westlaw searches for “global warming” and “greenhouse effect” pick up only a handful of citations before 1985. But it’s not totally clear what he meant, because “climate change” was used at the time to refer to a range of issues including acid rain, damage to the ozone layer, local weather control efforts, and desertification.
With more than 90% of global trade moving by ocean transport, maritime shipping is a major driver of the world economy. If we are to avert climate catastrophe, the shipping sector must immediately begin to eliminate the 1 billion-plus metric tons of greenhouse gases it emits every year. times more potent than CO 2 over the near term.
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.
However, not only is there an obvious energy imbalance (as seen by the growth of ocean heat content), it’s actually accelerating Loeb et al., Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!)
Whereas the science—synthesized in recent assessments and special reports by the Intergovernmental Panel on Climate Change (‘IPCC’)—emphasizes the deep interlinkages between issues of climate change, marine and terrestrial biodiversity loss, and ocean degradation, the international legal response is fragmented and uncoordinated.
From the ocean oscillations to trade winds, pressure systems that drives temperature, airborne particles that influence local conditions and even the phases of the moon and Earth's wobble all affect the climate (1). The east of the ocean is colder than normal while the west is warmer than average. What Climatology Is.
For example, the ongoing debate over the impact of certain pesticides in agriculture , greenhouse gas emissions are often a battle between the science and industry's attempts to muddy the science and government lobbying to roll back legislation (2). Typically used in conjunction with “greenhouse gas” but some emissions are not GHGs.
Transportation is the largest source of greenhouse gas emissions in California. Particulate matter harms lungs and hearts, while nitrogen oxide compounds contribute to ozone pollution and other health impacts. ← Previous Article: Seagrasses Turn Back the Clock on Ocean Acidification. featured image by Getty.
The California Supreme Court declined to review an intermediate appellate court’s decision upholding the statewide greenhouse gas cap-and-trade program. at its theme park in Jackson Township in Ocean County. California Supreme Court Denied Petitions to Review Ruling That Upheld Cap-and-Trade Program. A-3393-15T4 et al. June 22, 2017).
Oceans and seas cover around 2/3 of our planet. It's a natural resource and an economic one; many problems blight our oceans today, not least of all overfishing and the dumping of waste. This can also include the removal of invasive species. Marine Conservation. They are vital for life and home to thousands of species.
Hescox, Evangelical Environmental Network This guest essay first appeared in the York Daily Record on March 11, 2022 -- “Blessed are the peacemakers, for they will be called children of God” (Matthew 5:9, NIV) While Putin’s war on Ukraine may rage an ocean away, skyrocketing gas prices have brought it to America’s doorstep.
The trained marine biologist guides shared that water pollution in the Pacific Ocean and local bay have contributed to the population’s decline, and they talked about what is being done to improve it. I’ll never forget witnessing how a family moved around hunting their prey—sea lions—and celebrated by springing out of the water.
Circuit found that FERC failed to address the significance of a National Environmental Policy Act (NEPA) regulation that the petitioners argued required use of the social cost of carbon or another methodology to assess the impacts of the projects’ greenhouse gas emissions. Vecinos para el Bienestar de la Comunidad Costera v. 20-1045 (D.C.
EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. Circuit vacated the 2015 rule to the extent that it prohibited continued use of HFCs by companies that previously switched to HFCs from an ozone-depleting substance. In Mexichem , the D.C.
EPA : A draft policy assessment for the reconsideration of current Ozone air quality standards finds that there is insufficient scientific evidence that there would be a public health benefit to stricter ozone regulations. Integrated Ocean Observing System (IOOS®) Advisory Committee Public Meeting (May 11-13). NOAA – U.S.
This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. or 2 degrees without a radical reduction in greenhouse gas emissions and electrifying many of the things that currently run on fossil fuels. NOAA: Greenhouse gases spiked in 2021, with a record methane jump – Axios.
CEQ is also planning to revive guidance on how to factor greenhouse gas emissions and climate change into NEPA reviews, after Obama-era guidance was yanked by the Trump administration. The Bureau of Ocean Energy Management said it anticipates issuing a proposed rule in September updating its regulations for renewable energy generation.
UN seeks input about possible topics for the Ocean and Climate Change Dialogue. White House: President Biden met with the President’s Council of Advisors on Science and Technology after a meeting of the council, which focused on efforts to improve monitoring of greenhouse gas emissions and accelerate innovation in energy technology.
Chellie Pingree (D-ME)’s Coastal Communities Ocean Acidification Act ( H.R. This bill requires the National Oceanic and Atmospheric Administration to collaborate with state and local governments and Indian Tribes on vulnerability assessments related to ocean acidification. Legislative updates: The full House approved Rep.
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 climate change over the hundreds of years it remains in the atmosphere. 4:21-cv-00287-SPM (E.D. March 8, 2021).]] 2019); Birckhead v.
EPA : The draft annual greenhouse gas emissions inventory finds that U.S. The report notes that rates of atmospheric warming and ocean acidification in the Arctic may be as much as three to four times faster than the global average. In 2019, NISC disbanded the ISAC when the Trump administration cut funding for the council by 50%.
Senate Commerce Committee: The Committee voted to advance the Bolstering Long-term Understanding and Exploration of the Great Lakes, Oceans, Bays and Estuaries (BLUE GLOBE) Act ( S. EPA – 2021 Annual Joint Meeting of the Ozone Transport Commission and the Mid-Atlantic Northeast Visibility Union (June 15).
