As predicted in 1967 by Manabe and Wetherald , the stratosphere has been cooling. The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. So the net effect is less absorption and more emittence, and thus they give a cooling.
People now really are discussing the possibility of making intentional interventions to change the climate — or rather, to reduce some of the climate disruptions that are happening and coming due to human elevated greenhouse gases. These interventions would not precisely offset greenhouse-gas-driven climatechange.
On April 25, the Department of Environmental Protection announced the release of the 2024 ClimateChange Action Plan Update and 2024 Climate Impacts Assessment Report. Visit DEPs ClimateChange webpage for more information on these and other Pennsylvania climate initiatives.
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.
First, the cooling from the reflective materials they will inject, for which they are already selling carbon credits, charging $10 per gram of SO 2 released (!) Those following debates on active climate interventions have been expecting – and worrying about – something like this for a few years. Could this activity change the climate?
The world is gathering soon in Glasgow to debate how to eliminate greenhouse gas emissions over the coming decades. Does the climate keep warming, stay the same, or even cool? What are the political implications of the fact that climatechange will continue after emissions cease, or even potentially grow worse?
Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (AMO) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. Background.
We’ve been hearing a lot lately about geoengineering – the various scientific theories and governance ideas that could eventually lead to technological interventions to help cool the planet. Take this recent CNN story titled “Supporters of a controversial climate solution say it could be key. Anyone can float a balloon.
California is no stranger to the impacts of climatechange. From droughts to wildfires to rising sea levels and torrential rains, the state has felt the effects of a changingclimate in a variety of ways. Vapor pressure deficit is closely related to temperature and climatechange is causing temperatures to rise.
estimate of no further CO 2 -induced warming or cooling once global CO 2 emissions reach and stay at next zero. ZEC therefore causes no changes between SR1.5 Nature ClimateChange. In: ClimateChange 2021: The Physical Science Basis. IPCC (2014) ClimateChange 2014: Synthesis Report.
Remember ‘satellite cooling’?]. This was before Wentz and Schabel (1998) pointed out that orbital decay in the NOAA satellites was imparting a strong cooling bias (about 0.12 McNider, "Satellite greenhouse signal", Nature , vol. ClimaticChange , vol. K/decade) on the MSU2R (TLT) record. References J.R.
However, much of the attention paid to the flood risk of power plant sites has centered on nuclear plants, which also require a water source for the creation of steam, as well as for keeping the plant cool in an emergency. The link to climatechange is clearer, however, with floods.
Still, Suzie Stranik, the chair of the Seldovia Arts Council, recalls shutting down her greenhouse early and flushing her toilets sparingly. Some people have talked about the possibility of the wetlands drying up due to climatechange. It was quite a time here in our community, she says. It isnt all about drought, she says.
Climatechange adaptation refers to our individual and collective ability to cope with Mother Nature’s more intense weather punches in terms of extreme heat, drought, fire, flood and many other place based risks. I must acknowledge upfront that I have not interviewed either of them about their climatechange adaptation pessimism.
New research, using machine learning, helps project how the buildup of greenhouse gases will change clouds in ways that further heat the planet. By Bob Berwyn Scientists know that global warming is changing clouds, but they haven’t been sure whether those changes would heat or cool the planet overall.
By Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Methane production in the livestock sector greatly contributes to greenhouse gas emissions. Manure stored in the cool-temperate European climate is estimated to be responsible for approximately 12% of total methane emissions from the dairy system.
The AMOC has repeatedly shown major instabilities in recent Earth history , for example during the Last Ice Age, prompting concerns about its stability under future global warming, see e.g. Broecker 1987 who warned about “unpleasant surprises in the greenhouse”. For more on this see my Review Paper in Nature.
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. The second was a podcast with the somewhat troubled Chris Smith , an Australian journalist. .
They tallied 40 “interventions to slow down, halt, and reverse the effects of climatechange in the Arctic and northern regions.” Whether other mechanisms that disproportionately cool the Arctic would have the same effects has yet to be modeled, but seems worryingly plausible.
But this also raises other questions: 1) Can we expect the season to continue to lengthen as global warming from increasing concentration of globally well mixed greenhouse gas (GWM-GHG) continues to warm the Atlantic SSTs? Li, "Past and Future Hurricane Intensity Change along the U.S. 2016 ), could increase again in concentration.
It is also exerting an inadvertent cooling effect that masks a large fraction — perhaps a third to a half — of the climate forcing from previously emitted greenhouse gases that are already in the atmosphere. But cleaning this up will remove its cooling effect, which the IPCC recently estimated as 0.7°C.
Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climatechange was scant. There may also be a contribution from forcing inadequacies and, in some models, an overestimate of the response to increasing greenhouse gas and other anthropogenic forcing (dominated by the effects of aerosols).
Existing global energy projections underestimate the impact of climatechange on urban heating and cooling systems by roughly 50% by 2099 if greenhouse gas emissions remain high, researchers report. Read the full story from the University of Illinois Urbana-Champaign.
In a non-magic scenario, sales will ramp up to 100% electric vehicles between now and 2035 in order to meet state and federal greenhouse gas reduction goals for 2050. You’re out of immediate danger, but you don’t have power to keep warm/cool, refrigerate perishable food and medicines, etc.
Upfront equipment costs can also be lower because heat pumps provide both heating and cooling in one unit and they qualify for a number of government rebate programs. What’s more, switching to heat pumps would reduce a home’s carbon emissions for space heating, cooling, and water heating significantly. What is “Natural” gas, really?
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
But the hydrofluorocarbon refrigerants in these and other cooling devices are potent greenhouse gases and major drivers of climatechange. Summer is in full swing in the U.S., and people are turning up their air conditioners to beat the heat.
Through interviews with farmers, this post highlights both the climate-related challenges farmers are facing and how the IRA investments are building farmers’ resilience. As Doug puts it, “Climatechange is bringing more variability, not a consistent change toward a new pattern.”
As the Arctic is 30 degrees Celsius (50 F) warmer than what it should be right now, finding local solutions to cool down the poles suddenly doesn’t seem this far-fetched anymore. . Years ago I read a short article on how bringing more ice to the poles could help slow down climatechange. Image credits: NASA.
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. Cooling ice rinks. Cooling ice rinks. China, which is hosting the Olympics, have said they are striving to run what they call a ‘green’ Olympics.
“When the outside temperature is hot and humid, just perspiration is not enough to cool down the body since there is no evaporation of sweat,” says Abhiyant Tiwari, lead climate resilience and health consultant at India’s Natural Resources Defense Council. This could mean roughly 78 such days per year.
SB 253, authored by State Senator Scott Wiener, would require any company with over $1 billion in total annual revenue that does business in California to disclose three categories of greenhouse gas emissions: Scope 1 emissions, which are direct emissions from sources a company owns or controls, like on-site fuel combustion; Scope 2 emissions, which (..)
After the record breaking wildfire season that we had last year, it should be a wake up call for everyone that climatechange is here and that it’s only going to get worse. Heat pumps run on electricity and do not emit any greenhouse gasses so using one will be part of your contribution to reducing the effects of climatechange.
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. Until then, the most productive way to reduce uncertainties might just be to reduce emissions.
The August newsletter from the Pike County Conservation District includes articles on riparian buffers and climatechange and forests as part of the District's Forestry month education initiative. While these shifts can have a major impact on the planet’s forests, the forests can also have a major impact on climatechange.
If the sun was driving the warming, we’d see it in the stratospheric temperatures (which are cooling in line with expectations from the impact of CO2, not warming due to the supposed increase in solar activity). But we have mega-oodles (the SI unit) of additional data that tell us this conclusion cannot be correct.
The radiators are, in fact, cooling down, but their stored heat is still warming the air in the room. Emerging research is refining scientists’ understanding of how Earth’s committed warming will affect the climate. Today’s models can more explicitly represent the behaviour of greenhouse gases, especially carbon dioxide.
With the federal government and state of Maryland each having announced within days of each other, the mandated disclosure of greenhouse gas (GHG) emissions, we have received, maybe not surprising, many calls in the last two weeks inquiring “what are GHGs?” greenhouse gas emissions from human activities. emission trends.
“Natural gas”, also known as methane gas or fracked fossil gas, is a potent greenhouse gas that pollutes the environment and causes climatechange when it is burned and when it escapes into the atmosphere during extraction, production, and transportation. Enbridge should be made to stop deliberately misleading the public.”
Upfront equipment costs can also be lower because heat pumps provide both heating and cooling in one unit and they qualify for a number of government rebate programs. What’s more, switching to heat pumps would reduce a home’s carbon emissions for space heating, cooling, and water heating significantly. What is “Natural” gas, really?
This past summer was relatively cool and stormy, which limited the loss of summer sea ice in the Arctic. What’s more, despite the relatively cool temperatures this summer, this year’s Arctic sea ice contained some of the lowest amounts of multiyear sea ice ever recorded. Sorry, but we failed to add you to the list.
New Solid Carbon technology might be able to lock climate-warming carbon dioxide below ocean bedrock. What if scientists could turn back the clock on greenhouse-gas emissions – just a little? Photo credit: Pacific Institute for Climate Solutions. Basalt is a porous rock formed from cooling lava.
