Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.
As well as the (now) standard set of graphs related to increasing greenhouse gas concentrations , rising temperatures , reducing glacier mass, etc., since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution.
Still, both the National Oceanic and Atmospheric Administration (NOAA) forecast , released on May 24, and the Colorado State University (CSU) forecast , released on April 7, predict a season with above-normal activity— for the seventh consecutive year. This year broke the streak, and that is a good thing.
The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. We can explore the issues and pitfalls of this using the ‘simple model’ of the greenhouse effect we explored back in 2007. The simplest model for the greenhouse effect. A simple model with feedbacks.
Previous attribution research published by my Union of Concerned Scientists colleagues have allowed us to draw causal connections between sources of heat-trapping emissions and resulting impacts, like present day increases in atmosphericgreenhouse gas concentrations, air temperatures, sea levels , ocean acidification , and wildfire burned area.
So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. 128, 2022.

By Anders Lorenzen On the eve of the COP28 UN climate summit, The World Meteorological Organization (WMO), a United Nations (UN) body, has warned that the atmospheric concentration of greenhouse gases (GHG) is forecast to continue the trend that resulted in record-high CO2 measurements last year.
Governor Newsom’s May Revise budget proposal includes this item: Methane Satellites—$100 million Greenhouse Gas Reduction Fund on a one-time basis to expand the number of satellites launched for methane observations, which would provide weekly measurement of large methane emissions in the state and enhance enforcement capabilities.
Source: NOAA Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.

This follows from the need to run for much longer simulation periods (centuries, as opposed to days) (a factor of ~5000 more computation), and to include more components of the climate system (the full ocean, atmospheric chemistry, aerosols, bio-geochemistry, ice sheets etc.) 499-503, 2022. 496-499, 2022. 493-493, 2022.
Most prominently, because the approach is changing from rewarding specific technologies to rewarding anything that meets the greenhouse gas (GHG) emissions threshold of “clean”—hence the “tech-neutral” label—exactly how the government goes about determining whether or not something is actually eligible will be enormously important.
The increase regional VPD is mostly attributed to human-cause climate change (68%) and the rest (32%) is attributed to variations in the atmospheric circulation. High atmospheric “thirst” over multiple seasons or years can lead to drought conditions as vegetation dries out, and water flow in streams and rivers decreases.
Some of you will have heard of John Clauser because he was an awardee of the 2022 Nobel Prize in Physics for his role in the experimental verification of quantum entanglement. Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!) John Clauser’s theory of climate explained. Lyman, G.C.

That adds up to something in the ballpark of fifty million tons of CO2 that California kept out of the atmosphere during that decade beyond what happened in the power sector nationally. I used a December 2022 report from the California Air Resources Board as my primary resource. The Picture for Transportation is Less Clear.
Heightened flood risk The National Oceanic Atmospheric Administration (NOAA) said in a recent outlook that about 44 percent of the United States is at risk of floods this spring, equating to about 146 million people. This includes most of the eastern half of the country, the federal agency said.
It has taken 17 months to get a comment published pointing out the obvious errors in the Scafetta (2022) paper in GRL. Back in March 2022, Nicola Scafetta published a short paper in Geophysical Research Letters (GRL) purporting to show through ‘advanced’ means that ‘all models with ECS > 3.0°C 26-29, 2022.
Fortunately, the HS93 reconstruction was extended by our old friend Nicola Scafetta who (partially) used the discredited connection of SCL to global temperature to justify it ( Scafetta et al, 2022 , even citing the paper with the erroneous arithmetic highlighted by Laut back in 2003. 11-21, 2022. 801-812, 2003. Rendiconti Lincei.
Still, Suzie Stranik, the chair of the Seldovia Arts Council, recalls shutting down her greenhouse early and flushing her toilets sparingly. Compared to 2019, the summer of 2022 was significantly wetter. Atmospheric warming, however, will almost certainly affect the waters quality. Looming above town, the reservoir dwindled.
Earlier this month, the Intergovernmental Panel on Climate Change released Climate Change 2022: Mitigation of Climate Change. Nonetheless, here are some of what seemed to me to be important takeaways: Firstly, and most importantly, we’re not doing a very good job at mitigating greenhouse gas emissions.
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). These include the Landfill Methane Regulation , SLCP Reduction Strategy , 2022 Scoping Plan , and SB 1383.
Delayed action on emissions cuts may require even more (and more expensive) CDR – the 2024 United Nations Emissions Gap Report released this week found that 2023 greenhouse gas emissions set a new record, and current emissions reduction pledges for 2030 are insufficient to meet temperature goals.
Atmospheric CO2 levels at record highs. Globally, the levels of CO2 and methane which are the main greenhouse gases continued to climb, and both hit record highs in 2021. Levels of CO2 in the atmosphere reached 414.3 Levels of CO2 in the atmosphere reached 414.3 parts per million in 2021, up by around 2.4
It’s called the Social Cost of Carbon and it quantifies the damages of greenhouse gas emissions on health, the economy, and the environment. Did you know that economists have a tool for calculating the cost to society of continued reliance on fossil fuels? billion.
Human activity adds more than 50 gigatons of carbon dioxide to the atmosphere each year. What if scientists could turn back the clock on greenhouse-gas emissions – just a little? What if scientists could turn back the clock on greenhouse-gas emissions – just a little? Large-scale solutions are urgently needed. By Dr Kate Moran.
Under the LCFS each fuel pathway gets a unique carbon intensity (CI) based on a lifecycle analysis of the greenhouse gas emissions associated with the production and use of the fuel. The data from the 2022 USDA Agriculture Census was released on February 13 th and it confirms that dairy consolidation in California is continuing.
Under most emissions trading systems, regulated industries, which fail to meet their greenhouse gas emission target must make up the shortfall either with a punitive payment or by purchasing emissions trading credits. Regulated parties whose emissions are less than their target will receive credits for that emissions saving.
Guest Post by Julieta Juncosa Calahorrano , 2022-2023 Sustainability Leadership Fellow, and Ph.D. Candidate in the Department of Atmospheric Science at Colorado State University Growing up in Latin America, food was at the center of many family gatherings. greenhouse gas emissions in the year 2020.
Kirsten James – March 22, 2022. As long as greenhouse gases accumulate in the atmosphere, those risks will continue to rise. . “How industry responds to intensifying water scarcity and water quality risks globally will be critical.” Carl Ganter / Circle of Blue.
His research is focused on several topics of the atmospheric physics, the numerical simulation of coastal fronts, and severe meteorological events. In addition, he is currently Deputy Mayor of energy transition, mobility, and city cleaning management in Viladecans, a municipality of the metropolitan area of Barcelona. Dr Jordi Mazon.
The Inflation Reduction Act, President Joe Biden’s signature piece of legislation passed into law in 2022, allocated $19.5 Mechanisms of climate mitigation via soil carbon sequestration At the root of the excitement around soils is their ability to hold on to carbon, potentially drawing it out of the atmosphere and locking it away.
million in Alternative Fuel Incentive Grants (AFIGs) to 18 cleaner fuel transportation projects statewide that will reduce greenhouse gas emissions and other air pollutants. Vehicles alone release 21 percent of carbon dioxide emissions in the state, a known greenhouse gas and direct contributor to climate change.
This free online resource includes a searchable database that catalogues all of the climate change-related provisions in the 2022 Inflation Reduction Act (IRA), as well as a tracker that records actions taken by federal agencies to implement those provisions. The IRA Tracker homepage.
Understanding Climate Change & Greenhouse Gas Emissions. The greenhouse effect is a popular name for the earth’s warming effect which occurs naturally when gasses in the atmosphere trap heat from the sun and prevent it from escaping back into space. 2022: What Does the Latest IPCC Report Say?
While challenging, this could also create an opportunity to build co-benefits including job growth, biodiversity benefits, and equitable growth” (as cited in McKinsey & Company, 2022). These nature-based solutions actively contribute to mitigating greenhouse gas emissions and harnessing the immense potential of forests as carbon sinks.
While the idea of capturing carbon pollution before it reaches the atmosphere sounds good, in reality, it doesn’t actually work. That oil then gets burned, adding more carbon pollution to the atmosphere than what was originally captured. Carbon capture is a greenwashing tactic The new subsidy is for carbon capture projects.
In 2022, hydrogen earned bipartisan support at the forefront of the national clean-energy discussion, particularly as a vehicle for decarbonizing hard-to-electrify sectors like heavy-duty trucking and shipping, or manufacturing industries like iron, steel, and cement. The distinction here is important.
The Advisory Opinion addresses several key questions regarding application of the United Nations Convention on the Law of the Sea (UNCLOS) in the context of climate change, including the interaction between UNCLOS and the global climate change regime, and the specific obligations of States to reduce climate-damaging greenhouse gas (GHG) emissions.
In response to this challenge, public and private sector actors around the world are researching and deploying a variety of technologies designed to remove greenhouse gasses like carbon dioxide (CO 2 ) from the atmosphere. law surrounding CO 2 pipelines is characterized by glaring governance gaps.
Governor Edwards’ Climate Initiatives Task Force, charged with making recommendations to reduce greenhouse gas emissions originating in Louisiana, recently took another step towards that goal. This document contains proposed strategies and specific actions across several priority areas to be considered in reducing greenhouse gas emissions.
While rice yields are expected to decline due to rising temperatures, rice paddies are also among the biggest emitters of methane, a greenhouse gas. million in 2022-23. India is among the largest producers of sugar cane in the world, with the industry impacting the livelihood of nearly 50 million farmers across the country.
Here is a summary of the findings-- Americans continue to favor reducing greenhouse gas emissions as their preferred approach for staving off the worst impacts of climate change, according to new public opinion findings. These findings emerge from the Winter 2022 National Surveys on Energy and Environment (NSEE). & 7:30 p.m.
The recent boost for CDR is linked to an emerging trend in climate policy which understands CDR as supplemental to urgent action on decarbonization and overall greenhouse gas (GHG) emission reductions (rather than a replacement for those activities). Yet, key issues around definitions, guidance, and climate governance remain.
