A new study reaffirming that global climate change is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather. Read more on E360 →
An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2). So in comparison, the cooling effect of a 15 % AMOC slowdown is over 1,000 times larger than the direct cooling effect of the Greenland meltwater. References.
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.
A new study posits that the restoration of lost forest countered warming, keeping the region cool. Over the 20th century, the U.S. as a whole warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). Read more on E360 →
The project will study ways to reduce energy waste, capture heat, and find new fluids for the cooling process. The post Castrol Building Data Center Immersion Cooling Test Site appeared first on Environment + Energy Leader.
Climate change smothered us in heat this season, here in the US and across much of the world , but it has not affected us as equals: some of us can stay relatively safe and cool while many of us cannot and suffer instead. But I had access to a cool room. I had people who brought me cold drinks.
LiquidStack has partnered with colocation data center provider Standard Power to build the first large-scale colocation data center in the US to use 2-phase immersion cooling. The post LiquidStack Builds First Large-Scale US Data Center to Use 2-Phase Immersion Cooling appeared first on Environment + Energy Leader.
More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change. Read more on E360 →
The goal of the project: to better understand how humans might use such gases to cool an overheated planet. scientists have deployed a modified Korean War-era bomber to measure trace gases in the stratosphere that reflect sunlight. Read more on E360 →
As more high temperatures are forecast in the next few days, two of our climate scientists explain how people of color in four cities--Fresno, CA, Miami, FL, Mobile, AL, and Shreveport, LA--are at risk from the effects of urban heat islands.
Areas of rural countryside around cities are intended to prevent urban sprawl, but can also influence the climate within cities - and now researchers have quantified this cooling effect
After over a year of record-high global sea temperatures, the Atlantic is cooling off more quickly than ever recorded, which could impact weather around the world
After over a year of record-high global sea temperatures, the equatorial Atlantic is cooling off more quickly than ever recorded, which could impact weather around the world
A "negative greenhouse effect" means rising concentrations of CO2 and methane have slightly cooled parts of Antarctica’s upper atmosphere, but that could change as the air becomes more humid
An AI-assisted analysis of satellite images suggests the vapour trails produced by aircraft have a net cooling effect in the daytime because they reflect sunlight back into space
We recently received a question from a UCS supporter in Denver about how to best address the urban heat island effect. I forwarded this question to Dr. Juan Declet-Barreto, UCS senior social scientist for climate vulnerability, who is quite familiar with the situation.
The post Cool Green Book Review: October 2024 appeared first on Cool Green Science. New titles on birding, backyard nature, cowgirl conservation and more.
On October 17, the Department of Conservation and Natural Resources issued its fourth Fall Foliage Report saying consistently cold nights and cool days have spurred a very colorful change in Penn’s Woods! Bright color can be found from the southern Poconos though the middle and southern Appalachians.
A heat-pump-like system that relies on a phenomenon called electrocaloric cooling could heat or chill a room almost twice as efficiently as standard air-con units
The post Cool Green Holiday Book Review 2024 appeared first on Cool Green Science. Six books ranging from eels to owls to outdoor adventures that will make great gifts for your loved ones, or yourself.
People have a penchant for slapping Halloween-style names on creatures that are more cool than creepy. The post Goblin Shark & Ghost-faced Bat: Cool Critters with Creepy Names appeared first on Cool Green Science.
and the never-ending insistence of some solar enthusiasts that a dramatic cooling is right around the corner, these are not serious issues. The size of this cooling varies in the records, most of all in the satellite-derived AIRS v7 data, where the cooling is quite pronounced, and not at all in the ERA5 reanalysis.
Instead we made do by putting our perishable food on ice, making coffee with the JetBoil propane burner we have for camping (in an outdoor stairwell), and keeping the blinds closed to keep the apartment as cool as possible.
So-called “cool roofs” would bring down the average air temperature in cities like London during a heatwave more than green roofs, trees or solar panels do
While the IAEA has limited authority over nuclear safety even in peacetime, there are practical steps it could take to help the plant cope with any damage that would disrupt the systems that keep its highly radioactive reactor cores and spent nuclear fuel cool. hours, assuming the vessel remains filled with water. What about the spent fuel?
#WaysToSave Tip: Every degree you raise your air conditioning thermostat above 72 degrees can save up to 3% on cooling expenses. Save Energy Tip: For more energy-saving tips, visit PAPowerSwitch.com and check your utility's website for conservation and efficiency resources.
These areas experience higher temperatures relative to surrounding areas because they have a denser concentration of heat-trapping surfaces and limited green spaces that offer cooling benefits. Some themes that emerged were the lack of shading trees, vulnerable populations, the need to be creative when cooling, and issues related to water.
We would run around all day until we finally needed to cool off, which meant we would go to whoever’s house had the most sodas, ice cream, or popsicles. My dog Henry trying to stay cool during the heatwave. I think about people who are unhoused and unsheltered, and how challenging it is to stay cool and hydrated.
Smoke from the Australian bushfires, on the other hand, blocked sunlight, cooling the planet by around 0.06 They found that the decline in pollution during lockdowns produced clearer skies, allowing more sunlight to reach Earth, thereby warming the planet by around 0.05 degrees Celsius.

The AC doesn’t work (or you don’t run it because there go your wages), but at least the pedestal fan pointed directly at your body and some cool water help. It was simply not comparable to being outside for only one hour of one day and knowing that, at any time, I could go inside my home to cool off. .
Residents of notoriously polluted New Delhi, where half of the population lacks access to air conditioning, describe soaking in contaminated waters to stay cool. . Cooling monsoon rains will moderate temperatures, but not for another month. The infernal temperatures marked the final straw for Pir Koh’s already strained water systems.
That often brings to mind images of people trying to catch some shade under a baking hot sun or city kids cooling off in a fountain while their parents sweat on the sidelines. The types of clouds that have increased—specifically thick, precipitating clouds —reflect sunlight back into space during the day and have a cooling effect.
Nuclear plants hoover up enormous volumes of water for cooling, killing aquatic life and warming rivers in the process. Rivers provide a cooling effect on nearby lands, functioning as a natural air conditioner. Wind turbines and solar power, two sturdy and growing sources of renewable energy, require negligible amounts of water.
Siberia is today among the fastest-warming regions on Earth, but in the 7,000 years prior to the Industrial Revolution it saw summer temperatures steadily decline, according to a new study that underscores the profound impact of human-caused climate change on northern Russia. Read more on E360 ?.
Of the 24 CMIP6 models, a full 23 underestimate the sea surface cooling in the ‘cold blob’ And most of the CMIP6 models even show a strengthening of the AMOC in the historic period, which past studies have shown to be linked to strong aerosol forcing in many of these models (e.g.
What it does mean is that if cooling were disrupted to one or more of the reactors, then there would be a longer period of time—days instead of hours—for operators to fix the problem before the cooling water in the reactor cores would start to boil away and drop below the tops of the fuel assemblies, causing the fuel to overheat and degrade.
