The reason why 2016 was so warm was because of a strong El Nio eventa naturally-occurring cycle in the Earths climate systemwhich typically leads to a spike in Earths global-mean temperature. where 30,000-plus scientists gathered to present their latest research.
Researchers in Finland have observed a plant-induced cooling effect in the atmosphere, which strengthens as temperatures increase. Their results could provide important guidance for climate models that include the influence of aerosols in the atmosphere. Land and space observations.
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.
Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). 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. The key aspects were the inclusion of water vapour feedback as temperatures increased, and the use of ‘convective adjustment’ to maintain stability of the lower atmospheric column. 1975) , and Bryan et al.
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. Image: Prof.
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
Someone’s bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences, says climatescientist Kate Ricke. Read the full story in Wired. Read more →
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!) Johnson, A. Lebedeff, P.
As air sunk through the atmosphere, it got squeezed and heated. Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly. Understanding cloud formation is key to improved climate models.
For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Prof Martin Siegert is an award-winning Antarctic glaciologist and climatescientist. The world’s largest ever heatwave (38.5C
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.
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.
But, Michael Mann is a well known climatescientist whose research in studying the “paleoclimate,” or ancient climate, has featured prominently in the politically charged debate about climate change. who referred to an article by Simberg article in his article.
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.
In this blog, I explain the science behind these extreme weather events and pinpoint how additional heat-trapping emissions in Earth’s atmosphere are responsible. The Earth is warming The burning of fossil fuels has led to an increase in pollutants such as carbon dioxide in the atmosphere since the industrial revolution began in the 1800s.
This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. It’s the third chapter in the IPCC’s mammoth sixth assessment report, part of a series of studies that summarize the state of climate science and the planet released roughly every seven years.
It needs to be an informed decision with equal input from climatescientists and economists. In 1970 in the Boston Globe newspaper, there was a scientist from the atmospheric research in Boulder, Colorado predicted that an ice age would be upon us by the 21st century. Pennsylvania must get this decision on RGGI right.
