'Tone-deaf’ fossil gas growth in Europe is speeding climate crisis, say activists - Guardian - Energy
Mar 2 · Just 2% of continent’s gas capacity has planned retirement date despite pledges to decarbonise, study shows
Europe’s “tone-deaf” expansion of fossil gas is accelerating climate breakdown and increasing reliance on hostile regimes, campaigners have warned.
Just four of Europe’s gas-fired power plants have a retirement plan and new projects will increase the continent’s gas generation capacity by 27%, according to analysis from the campaign group Beyond Fossil Fuels.
It argues that the dash for gas contradicts the International Energy Agency’s recommendation that rich countries decarbonise their electricity grids in the next 10 years to stop the planet from heating 1.5C.

'Winners and Losers' as Global Warming Forces Plants Uphill - Science Daily - Earth and Climate
Mar 24 · Some plant species will "win" and others will "lose" as global warming forces them to move uphill, new research shows.
Scientists examined the current range of more than 7,000 plant species in Brazil's Cerrado savanna, and estimated shifts based on warming by 2040.
The fate of plant species will depend on where they live: lowland species can move uphill for cooler conditions, but mountain plants have nowhere to go.
The study was carried out by the universities of Exeter and Campinas, the Royal Botanic Garden Edinburgh and Trinity College Dublin.
"Every plant and animal species has a 'geographical range' -- the area where conditions are suitable for it to ...

A guide to electric car misinformation (part 1) - Heated World
Mar 27 · The closer we get to the 2024 presidential election, the more sketchy information you’re going to hear about electric cars.
Both Joe Biden and Donald Trump have decided to make electric cars central to their campaigns. Biden is doing this by promoting his administration’s efforts to expand EV production and ownership, and Trump is doing this by attacking those efforts.
GOP polling has shown that attacking electric vehicle policy has been “amazing” for Republicans, former Trump energy advisor Michael McKenna recently told the New York Times. And Biden’s EV policies have drawn praise from both green groups and the United Auto Workers union - two important political ...

A microalgae–material hybrid promotes carbon neutrality - PHYS.ORG - Biology
Mar 25 · With the intensification of global warming and the proposal of China's dual carbon reduction goals, the role of microalgal photosynthesis is getting more and more attention. Therefore, exploiting microalgae photosynthetic energy is a promising approach to energy transition for carbon peak and neutrality.
However, the photosynthetic conversion efficiency is a major limitation of microalgae biofuel production. Generally, only about 4–8% of the light energy can be converted into chemical energy in the form of biomass (the theoretical maximum is 9%). Therefore, the microalgae production for biofuels cannot meet the human energy needs.

Climate Change Alters the Hidden Microbial Food Web in Peatlands - Science Daily - Earth and Climate
Mar 24 · The humble peat bog conjures images of a brown, soggy expanse. But it turns out to have a superpower in the fight against climate change.
For thousands of years, the world's peatlands have absorbed and stored vast amounts of carbon dioxide, keeping this greenhouse gas in the ground and not in the air. Although peatlands occupy just 3% of the land on the planet, they play an outsized role in carbon storage -- holding twice as much as all the world's forests do.
The fate of all that carbon is uncertain in the face of climate change. And now, a new study suggests that the future of this vital carbon sink may be affected, at least in part, by tiny organisms that are often ...

Climate change is altering Earth’s rotation enough to mess with our clocks - Washington Post - Climate and Environment
Mar 27 · Climate change is messing with time itself.
The melting of polar ice due to global warming is affecting Earth’s rotation and could have an impact on precision timekeeping, according to a paper published Wednesday in the journal Nature.
The planet is not about to jerk to a halt, nor speed up so rapidly that everyone gets flung into space. But timekeeping is an exact science in a highly technological society, which is why global authorities more than half a century ago felt compelled by the slight changes in Earth’s rotation to invent the concept of the “leap second.”
Climate change is now making these calculations even more complicated: In just a few years it may be ...

Mar 27 · In a strange twist, global warming could even help out timekeepers by delaying the need for history's first "negative leap second" by three years, a study published on Wednesday suggested.
Experts fear that introducing a negative leap second—a minute with only 59 seconds—into standard time could cause havoc on computer systems across the world.
For most of history, time was measured by the rotation of the Earth. However in 1967, the world's timekeepers embraced atomic clocks—which use the frequency of atoms as their tick-tock—ushering in a more precise era of timekeeping.

Entanglement entropies of nuclear systems found to grow as the volume of those systems - PHYS.ORG - Earth
Mar 25 · Large entanglement entropies indicate that a system has strong correlations to its environment. In many systems, the entanglement entropies are proportional to the area that separates a system from its environment. This is also true for black holes, where the energy-related entropy growth is proportional to the area of the event horizon. But the nuclei of atoms are different. The complicated interactions in nuclei lead to entanglement entropies that grow like the volume of the system of interest, not like its surface area.

If you've got a dark roof, you're spending almost $700 extra a year to keep your house cool - PHYS.ORG - Technology
Mar 26 · It's very different in Australia. New housing estates in the hottest areas around Sydney and Melbourne are dominated by dark rooftops, black roads and minimal tree cover. Dark colors trap and hold heat rather than reflect it. That might be useful in winters in Tasmania, but not where heat is an issue.
A dark roof means you'll pay considerably more to keep your house cool in summer. Last year, the average household in New South Wales paid A$1827 in electricity. But those with a lighter-colored cool roof can pay up to $694 less due to lower cooling electricity needs. Put another way, a dark roof in Sydney drives up your power bill by 38%.

Mar 1 · February 24, 2024JPEG
Ice coverage on the Great Lakes typically reaches its annual peak in late February or early March. But at that time in 2024, the lakes were conspicuously free of ice. Owing to warmer winter weather and above-average surface water temperatures, ice cover stood at historic lows.
Since satellite-based measurements began in 1973, ice coverage at its maximum winter extent exceeds, on average, 40 percent. In late February 2024, it stood at only about one-tenth of the average maximum. The VIIRS (Visible Infrared Imaging Radiometer Suite) sensor aboard the Suomi NPP satellite acquired this image of the lakes on February 24, 2024.

Satellite data shows how drought changes wildfire recovery in the West - PHYS.ORG - Earth
Mar 27 · The West has been witnessing a trend of increasing number and intensity of wildland fires. Historically a natural part of the region's ecology, fires have been exacerbated by climate change—including more frequent and intense droughts—and past efforts to suppress fires, which can lead to the accumulation of combustible material like fallen branches and leaves. But quantifying how fire and drought jointly affect ecosystems has proven difficult.
In the new study, researchers analyzed over 1,500 fires from 2014 to 2020 across the West, and also gathered data on drought conditions dating back to 1984. They found that droughts make it harder for grasslands and ...

Severe Hurricanes Boost Influx of Juveniles and Gene Flow in a Coral Reef Sponge - Science Daily - Earth and Climate
Mar 24 · Named for its ropy-looking long branches, Aplysina cauliformis, a coral reef sponge, provides a critical 3D habitat for marine organisms and helps to stabilize the foundation of coral reefs. However, these upright branching sponges are highly susceptible to breaking during storms, which increases sponge fragmentation and contributes to population clonality and inbreeding.
Many sponges can survive severe damage and undergo frequent fragmentation, which is considered a mechanism for asexual reproduction. While fragmentation is a commonly utilized reproductive strategy in rope sponges, they also can reproduce sexually by producing larvae. How and whether they recolonize following ...

Study documents slowing of Atlantic currents - PHYS.ORG - Earth
Mar 25 · Mishonov and co-authors Dan Seidov and James Reagan from NOAA discovered that the current system's flow remained stable and consistent from 1955 to 1994. However, in the mid-1990s, AMOC strength began to decline and the current began to move slower, which the scientists attribute to the continued warming of the ocean's surface and the accompanying changes in the salinity of its upper layers.
AMOC, which includes the Gulf Stream, carries warm water toward higher latitudes, releasing heat into the atmosphere and bringing cold waters to the tropics. This forms a continuous loop that redistributes heat across the ocean.
"If AMOC slows down, the heat exchange will be reduced, ...

Study reveals flood mud burden on Moreton Bay - PHYS.ORG - Earth
Mar 25 · Dr. Alistair Grinham from the School of Civil Engineering said recent floods deposited mud across 98% of the Bay, compromising its remaining areas of clean sand and hastening the growth of a muddy "dead zone."
"In 1970 Moreton Bay had about 400 square kilometers of clean sand and now it has just 30 square kilometers," Dr. Grinham said.
"Clean sand is defined as having less than one percent of mud content so some areas may look lovely and white, but the flood sediment is insidiously changing the nature of the seabed and affecting water chemistry.
"While sand is inert, flood sediment contains clay, organic matter and nutrients from rural and suburban areas which ...
