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.
McNider and Christy, Feb 19th 2014, Wall Street Journal Most of the op-ed is a rather tired rehash of faux outrage based on a comment made by John Kerry (the then Secretary of State) and we can skip right past that. Remember ‘satellite cooling’?]. The version of the MSU2R product at the beginning of 2014 was version 5.5,
The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans.
It is not as though people have not tried – we discussed this here in 2014, where we made a plea for better graphs of the global temperature. All of which adds to the uncertainty. Now, 10 years later, we finally have something. The first factor increases the apparent sensitivity, and the second decreases it.
Source: Data from IPCC (2014), Rogelj et al (2018), and IPCC (2021). Source: Data from IPCC (2014), Rogelj et al (2018), and IPCC (2021). estimate of no further CO 2 -induced warming or cooling once global CO 2 emissions reach and stay at next zero. IPCC (2014) Climate Change 2014: Synthesis Report. Leitzell, E.
After the EPA proposed the Clean Power Plan in 2014, for example, fossil fuel interests and their backers tried to argue that the proposal’s 2030 emission-reduction targets were completely unrealistic, and that the country would see astronomically high costs and blackouts due to the rule.
The radiative forcing bar chart has gone full circle: Almost every IPCC report has a version of the radiative bar chart showing the contributions over the historical period of all the different forcings (greenhouse gases, aerosols, solar, etc.). 1, SPM, AR5.
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. Here a quote from Liu et al.
The Chicago City Council makes new cooling rules after a heat wave killed three people in an apartment building. The expansions to the cooling requirements will help keep our most vulnerable residents safe as we continue to see the impacts of climate change.”. A case before the U. Maria Hadden, 49th Ward Alderman. Other News.
This past summer was relatively cool and stormy, which limited the loss of summer sea ice in the Arctic. Since 2007, only 2009, 2013 and 2014 had more ice at the end of the melt season. Thanks for signing up for Ocean Conservancy emails. That’s equivalent to the combined size of Texas, California and Montana.
The challenge forms part of the UK’s National Quantum Technologies Programme (NQTP) , which was set up in 2014 to fund and spur on the rapidly growing UK quantum industry. Operating at room temperature – how cool is that! – They can monitor leaks of methane – a potent greenhouse gas – from gas and oil wells. Award winners.
SG would cool the Earth, temporarily and imperfectly offsetting some of the climate effects of elevated greenhouse gases, by reflecting a bit (around 0.5% But there is now one big exception: research on solar geoengineering (SG). to 1%) of incoming sunlight.
To date, BlocPower and its contractor partners — which include Augmented Construction , Urban Energy , VRF Solutions , Super Cool HVAC and Ch! Buildings contribute 67 percent of New York City’s greenhouse gas emissions , with apartment buildings representing the biggest share of that. Roughly a third of U.S.
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.
Utilizing manure nutrients efficiently means that risk of loss of nitrogen, phosphorus, sediment, and greenhouse gas is minimized. It complements Phoenix Contact’s Combined Cooling, Heating, and Power (CCHP) system, which generates about half of the facility’s electric requirements.
Subsequently, Japanese greenhouse gas emissions and electricity costs for industrial and residential consumers have skyrocketed. The country had planned a massive expansion of its nuclear power program in a bid to reduce greenhouse gas emissions, with its. due to a malfunction in a secondary cooling system. 2010 Energy Plan.
A second bill would require annual reporting of the greenhouse gas (GHG) emissions caused by a covered firm’s operations. The Environmental Protection Agency (EPA) has adopted a Greenhouse Gas Reporting Rule [25] requiring facilities that emit more than 25,000 metric tons of carbon dioxide equivalent to report their direct GHG emissions. [26]
