A new analysis of satellite cloud observations finds that global warming causes low-level clouds over the oceans to decrease, leading to further warming. The work, led by researchers at Lawrence Livermore National Laboratory (LLNL), in collaboration with colleagues from Scripps Institution of Oceanography and the NASA Langley Research Center.
Study Finds 6⁰C Cooling on Land during the Last Ice Age, With Implications about Future Global Warming
Prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth’s climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates.
ALBANY, N.Y. (May 6, 2021) – A new report released this week by the National…
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study. But if global warming exceeds the target – 2 degrees Celsius (3.6 degrees Fahrenheit) – the risk of ice shelves around the ice sheet’s perimeter melting would increase significantly, and their collapse would trigger rapid Antarctic melting. That would result in at least 0.07 inches of global average sea-level rise a year in 2060 and beyond, according to the study in the journal Nature.

Should humans use technology to put the brakes on global warming? Stratospheric aerosol intervention (SAI) is a climate intervention that has been studied as a way to help cool the Earth. But what would be the consequences to natural systems of SAI? This question is being examined by a large scientific research team.
As the planet heats up, are lakes releasing more carbon dioxide into the atmosphere? With a prestigious National Science Foundation Faculty Early Career Development (CAREER) grant, researcher Kevin Rose will examine large-scale patterns in concentrations of carbon dioxide (CO2) and dissolved oxygen to answer the question.

Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.

Even if all countries meet their Paris Agreement goals for reducing emissions, Earth has only a 5% chance of staying below 2 C warming this century, a 2017 study showed. But reductions about 80% more ambitious, or an average of 1.8% drop in emissions per year rather than 1% per year, would be enough to meet the agreement’s stated goal, analysis shows.
Climate change is bleaching and killing corals, but researchers from Michigan State University and the University of Hawaii are investigating how some can stand up to a warming world.

Global warming. Climate change. Coral bleaching. These are a few issues that are negatively impacting our marine world. And now you can add underwater heatwaves to the list – something an NSU Researcher is studying.
Scientists have resolved a key climate change mystery, showing that the annual global temperature today is the warmest of the past 10,000 years – contrary to recent research, according to a Rutgers-led study in the journal Nature. The long-standing mystery is called the “Holocene temperature conundrum,” with some skeptics contending that climate model predictions of future warming must be wrong. The scientists say their findings will challenge long-held views on the temperature history in the Holocene era, which began about 12,000 years ago.
Obamacare will get retooled, not repealed. A national mask mandate will boost consumer spending, research shows (though don’t expect much from homeowners, they’re strapped). The $300 billion for R&D should go to D, not R. So forecasts an array of WashU experts.

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.
A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education.
The 19-nation study is the largest investigation to date of the relationship between our changing climate and children’s diet diversity.
Of the six regions examined–in Asia, Africa, and Central and South America–five had significant reductions in diet diversity associated with higher temperatures.
The three-part tool offers an interactive way to view up to two millennium’s worth of paleoclimate data around the globe.

The planet is committed to global warming in excess of 2 degrees Celsius (3.6°F) just from greenhouse gases that have already been added to the atmosphere. This is the conclusion of new research by scientists from Nanjing University, Lawrence Livermore National Laboratory (LLNL) and Texas A&M University, which appears in the latest edition of Nature Climate Change.
Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study.
Conservation of fish and other marine life migrating from warming ocean waters will be more effective and also protect commercial fisheries if plans are made now to cope with climate change, according to a Rutgers-led study in the journal Science Advances.

A new report evaluating the efficacy of climate action plans and commitments of the 100 largest U.S. cities finds the leadership of these municipalities stands as an important counter to the federal government’s rollback of climate policies and departure from the Paris Agreement. Yet, despite genuine achievements by some, roughly two-thirds of cities are currently lagging in their targeted emissions levels, and, on average, all cities in the report need to cut their annual emissions by 64% by 2050 in order to reach their respective goals.

In unprecedented times like this, we often reflect on what we as humans can do to better our world. In terms of climate change, there are many ways we can make a difference, whether on a small or large scale, in order to create a sustainable and healthy environment for all.
Irvine, Calif., Oct. 8, 2020 – An international team of researchers – including Earth system scientists at the University of California, Irvine – recently completed the most thorough review yet of nitrous oxide from emission to destruction in the planet’s atmosphere. In addition to confirming that the 20 percent increase in the amount of the greenhouse gas since the start of the Industrial Revolution can be totally attributed to humans, the team expressed doubt about the ability to reduce emissions or mitigate their future impacts.
A new study shows that rising nitrous oxide emissions are putting reaching climate goals and the objectives of the Paris Agreement in jeopardy.
The University of New Hampshire will lead research as part of a $1.5 million award from the National Science Foundation to better understand how interactions between plants, microbes and soil minerals in permafrost, a subsurface layer of frozen soil covering a fourth of the Northern Hemisphere, stimulate the release of carbon which adds to the warming Arctic.
A new study shows that coordinated international action on energy-efficient, climate-friendly cooling could avoid as much as 600 billion tonnes CO2 equivalent of greenhouse gas emissions in this century.

Enteroviruses that make their way into surface waters can be inactivated by heat, sunshine and other microbes, reducing their ability to spread disease. But researchers report that global warming could cause viruses to evolve, rendering them less susceptible to these and other disinfectants, such as chlorine.
