New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information. What role should scientists play in nuclear weapons policy?
Scientists are sounding the alarm because this warming is shockingly bigbigger than what we would have expected given the long-term warming trend from fossil fuel-caused climatechange. Albedo is the total reflection of incoming solar radiation by Earth. But why were 2023 and 2024 so warm? What is albedo?
The IPCC compiles scientific insights on climatechange, informing policymakers and the public about risks and possible actions. In essence, combined with climate models, they provide a way to envision the consequences of different actions or inactions. What Are Future Climate Scenarios?
Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. But what exactly would cause the AMOC to collapse?
In my blog on the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), which is the conveyor belt of water moving in the Atlantic Ocean, I discussed how regions around the equator are warmer than the poles due to different amounts of incoming solar radiation, that is, energy from the sun. What do I mean by this?
I have a feeling that we are seeing the start of a new wave of climatechange denial and misrepresentation of science. What he hasn’t understood is that the IPCC merely assesses published climate research, much of which is conducted with global climate models that indeed treat the earth as a sphere.
That is long enough to see that there has been a noticeable trend in the Earth’s Energy Imbalance (EEI), mostly driven by a reduction in the solar radiation reflected by the planet, while the outgoing long wave radiation does not appear to contribute much. A paper last year (Goode et al., The total radiative forcing is.
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. .
The Intergovernmental Panel on ClimateChange has concluded that CDR will be needed, alongside deep emissions cuts, to limit global warming to 1.5 Solar radiation management is distinct from CDR. Notably, it would not in any way change the text of the London Convention or Protocol, or the 2013 amendment.
Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climatechange was scant.
What role is climatechange playing? As climatechange increases the frequency or intensity of extreme events such as wildfires, heat waves, and heavy downpours, there is an increase in the potential for different types of risks to coincide or for a climate-related event to trigger a cascade of non-climatic consequences.
Climatechange under other federal statutes. Climatechange as substantial impact requiring discussion in environmental impact statement. Climatechange as reason for threatened or endangered status under Endangered Species Act. SEC rules on disclosure of climate-related risks. Takings issues VII.
The labs – including CERN, the European Space Agency, Fermilab and the Los Alamos National Laboratory – have announced that they will step up their scientific collaboration on carbon-neutral energy and climatechange as well as share best practices to improve the carbon footprint of big-science facilities. Eager to learn.
Solar activity provides no alternative explanation for today’s climatechange Dagsvik and Moen claim that recent research indicates that variations in the sun’s magnetic field are of great importance for long-term fluctuations in solar activity. Our job is to be thorough and verify questionable results. It has taken time.
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.

Now researchers have performed X-ray computed tomography on samples of wood from the hull at the European Synchrotron Radiation Facility in Grenoble, France. How will climatechange affect your part of the world in your lifetime? The research is described in Matter.
The project is also under scrutiny for its contributions to climatechange. The Pennsylvania ClimateChange Act of 2008 acknowledges that fossil fuel production significantly contributes to climate deterioration. Note: There is no present requirement for DEP to make this assessment.] “At
By Bob Berwyn A scientific showdown over whether dispersing massive amounts of reflective particles high into the atmosphere could temporarily and safely mask global warming intensified this week, as a group of more than 60 researchers published a letter Monday calling for accelerated research and small-scale field experiments into what is called solar (..)

Chris Lennard from the University of Cape Town takes us through different aspects of climatechange adaptation. The good news is that there are some initiatives on climatechange adaptation which involve climate scientists such as the Infrastructure and Climate Network ( ICNet Global ).
That’s why gas-powered cars need complex and expensive radiator systems with their associated belts, pipes, and heat exchangers. The post Electric Vehicles Combat ClimateChange appeared first on Global Green. A significant portion of the energy from gasoline is converted to unwanted heat. You’ll feel the loss of energy.
Read out of context, that description fits climatechange too, of course. So why do so many ignore scientists’ predictions about climatechange?!!” The eclipse is also a teachable moment for what is, and is not, causing climatechange. But that doesn’t mean the sun is causing climatechange.”
We’ve published a number of articles over the years (see e.g. here , here , here , here , here , and here ) demonstrating that studies that use such an approach to define the AMO end up mis-attributing to a natural “oscillation” what is actually human-caused climatechange. Now we have come full circle.
Against the backdrop of Chile’s Atacama Desert, the Salar de Atacama Mine radiates with a futuristic blue light—its cerulean pools glow like tessellated computer screens, a stark contrast to the muted landscape that surrounds them. By Laura Gersony, Circle of Blue — January 17, 2022.

EPA’s Climate Pollution Reduction Grants (CPRG) On September 20, 2023, EPA announced the Climate Pollution Reduction Grants (CPRG). Administered by the Office of Air and Radiation, this program is $4.6 Throughout this year, EPA has heard from numerous stakeholders at many forums and made these interesting changes to the design.
eV, use back surface reflectors to divert unusable sub-bandgap radiation back to the source, and are optimized for heat sources at temperatures of 1900–2400°C. They also hope to further improve the cells’ efficiency to 50% by increasing the fraction of unusable radiation they reflect to 97-98%. New efficiency of 41.1%.
By Bob Berwyn Antarctica’s vast ice fields and the floating sea ice surrounding the continent are Earth’s biggest heat shields, bouncing solar radiation away from the planet, but two studies released today show how global warming is encroaching even on the sunlight reflector in the coldest region on the planet.
Almost 20 years later, the 2020 and 2021 wildfires seasons saw those orange skies spread across the West and gave me new insight into how climatechange will make that glow an increasingly present reality for more people around the world. For one, plants rely on solar radiation to grow, and the U.S. Since so many major U.S.
By Bob Berwyn After sampling the atmosphere above the Arctic for more than a year during the MOSAiC research voyage , climate scientists say the ozone layer, Earth’s protection against intense ultraviolet radiation, is at risk, despite the progress made in protecting atmospheric ozone by the 1987 Montreal Protocol , the global treaty that banned ozone-harming (..)
Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room. The radiators are, in fact, cooling down, but their stored heat is still warming the air in the room.

Guest Post by Philip Cafaro , Professor in the Department of Philosophy at Colorado State University Scientists and climate ethicists argue that more attention needs to be given to population growth’s role in the climate crisis. Addressing population, therefore, must be part of humanity’s response to global climatechange.
Even more surprisingly, that changes the atmosphere’s radiation profile. We were shocked to discover that we had destabilized the climate on Planet X. It turns out — I’ll bet even most AIs don’t know this — the oxidized carbon byproduct of our fuels has a nasty tendency to pile up in the atmosphere.
But this simplified pathway misses a key step in cloud formation–and one that could help us combat climatechange. But if they are thin and transparent, they reflect very little sunlight and instead trap a lot of the heat radiating from the Earth, resulting in a net warming effect. C temperature target. 2010, November 2).
Without the Montreal Protocol, more solar radiation would have destroyed plants, lessening the CO2 they absorb. -- Read more on ScientificAmerican.com.
This knowledge can help with solar radiation management in marine ecosystems, including the Great Barrier Reef. As frequency and severity of mass bleaching events are expected to increase in the future, researchers are looking for ways to protect corals from excessive radiation and temperatures.
” Tony DeBrum, Marshallese politician and government minister Nuclear testing spread radioactive material across the islands, in some cases causing immediate radiation poisoning, and in the long term leading to persistent health problems across generations, including cancers and reproductive issues like miscarriages and stillbirths.
Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in … Continue reading How fast can we stop Earth from warming? If people everywhere stopped burning fossil fuels tomorrow, stored heat would still continue to warm the atmosphere.
NIF can also be used to generate x-rays and gamma-rays which are used to study radiation hardness of weapons components and assemblies. Thus, this result should not distract us from the fact that urgent action to develop clean energy sources and combat climatechange is required in this decade. A bumpy road to fusion.
Of all the troubling headlines emerging from the release of the Intergovernmental Panel on ClimateChange (IPCC) WG1 report, one warning will surely dominate headlines in the next days and weeks: Earth is likely to reach the crucial 1.5?
