Its a great question, but the warming effect from heat-trapping gases far outweighs the cooling effect from industrial aerosols. Over the last few decades, there has been an observed decrease in total planetary cloud cover , especially over the North Atlantic Ocean off the Northeast US coast.
In an unchanging climate, the random fluctuations would lead to warming in some parts of the world and cooling in others. In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling. I could go on.
There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climatescientists. Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993).
As climatescientists we tend to look at the IPCC reports a little differently than the general public might. 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!) Figure SPM 8.
Tiny particles of plastic in the atmosphere can affect Earth’s climate, according to Laura Revell at the University of Canterbury in New Zealand and colleagues. Although the threats these microplastics pose to natural ecosystems are now being studied extensively, their influence on Earth’s climate is still virtually unknown.
For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Several floating ice shelves – the massive slabs of ice that push back grounded ice from flowing into the ocean – have catastrophically broken up in a matter of days because of such melting.
The discovery by Ladislav Skrbek at Charles University and colleagues could help climatescientists to better understand the flow of heat through Earth’s atmosphere, and may also lead to better designs of heat exchangers. Efficiency booster. They examined different oscillation frequencies in the range 0.006–0.2
An area of high pressure above the Pacific Ocean was driven eastwards through the jet stream by a “Rossby wave” – a planetary-scale fluctuation arising from the Coriolis force. The Rossby wave eventually “broke”, dumping its energy – like an ocean wave hitting the shore – to create an area of high pressure locked over western Canada and US.
The first climate change presentation I saw was back in the 1970s when I was working for the National Weather Service. Murray Mitchell, was the top climatescientist for NWS. While that got the bulk of the publicity, Dr. Mitchell assured us that the warming of the climate would be the biggest problem in the future.
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.
Climatescientists at the Union of Concerned Scientists (UCS) have dubbed the six-month stretch from May through October the “ Danger Season.” Not only has much of what climatescientists have been warning about come to pass, many of the extreme weather events the planet is now experiencing are worse than they expected. “To
The petitioners hope that disaster declarations can unlock federal funds for short-term relief such as cooling centers, water supplies, emergency air conditioning and air filtration systems, and financial assistance for evacuations.
It was a sorry exclamation point on the National Oceanic and Atmospheric Administration’s assessment that 2023 was the Earth’s warmest year on record. Texas A&M climatescientists Andrew Dessler and Jangho Lee told the AP that last year’s real national annual heat death toll may be more like 11,000–and that it could get much worse.
Scientists at the National Oceanic and Atmospheric Administration (NOAA) are responsible for weather forecasts and severe storm warnings, information we likely take for granted. Climatescientist Katharine Hayhoe asserts that talking about climate change is the most important thing we can do.
Each storm made history in its own right: Beryl was the earliest Category 5 storm on record in the Atlantic Ocean, Helene broke rainfall records in Georgia, North Carolina, South Carolina, and Tennessee, and destroyed tens of mountain communities, and Milton was the second fastest intensifying storm since 1979.
Other methods, like tech to suck carbon out of the air or intervening in marine systems to boost the sequestration potential of oceans, are less vulnerable to reversal and don’t pose the same land issues, but most are in their infancy. degrees or try to cool the planet back down through the massive use of CDR.
It needs to be an informed decision with equal input from climatescientists and economists. Report after report, scientist after scientist, they continue to demonstrate that our lack of movement on climate change is leading to stronger and more frequent and dangerous weather patterns and rising ocean waters.
