Last month, 44 climatescientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. The Earth’s climate system does not like imbalances in heat!
The evidence shows that hydroclimate whiplash has already increased due to global warming, and further warming will bring about even larger increases, says Daniel Swain, a climatescientist with UCLA and UC Agriculture and Natural Resources who led the study. But e xtreme weather is already the context.
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.
Climate models are the main tool scientists use to assess how much the Earths temperature will change given an increase in fossil fuel pollutants in the atmosphere. As a climatescientist, Ive used them in all my research projects, including one predicting a change in Southwestern US precipitation patterns.
Climate models are the main tool climatescientists use to predict how Earth will respond to more heat-trapping pollutants in the atmosphere. But what exactly is a climate model? Lets start off easy by breaking down the phrase climate model.” What causes a circulation? temperature, rainfall, etc.)
It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. The Keeling curve, highlighted with the release of important climate reports and climate summits.
Research with climate models in recent years shows that when carbon dioxide emissions stop, the rise in atmospheric temperatures will likely also stop. The oceans absorb much of the carbon dioxide lingering in the atmosphere, which contributes to ocean acidification. 2C above the preindustrial average.
Skip to main content Scientific American Opinion July 4, 2025 5 min read A Thought Experiment Reveals the Fingerprints of Climate Change Came Early Climate change left its signature on the atmosphere early in the industrial revolution, reveals a thought experiment investigation By Ben Santer , Susan Solomon , David W.
Initially it used four different emission storylines from the Special Report on Emissions Scenarios (SRES) as a scientific basis, however, recognizing the need for a more flexible and policy-relevant framework, scientists developed the Representative Concentration Pathways (RCPs) for the IPCC reports.
In videos and Congressional testimony , Wright portrays himself as a truth teller, while falsely claiming that climatescientists and renewable energy advocates are deceptive. In the last sixty years, the amount of carbon dioxide in the atmosphere has grown 100 times faster than it did at the close of the last ice age.
AAS: How did you come to be a climatescientist? Pursuing that love, I went on to study and earn my PhD in atmospheric science. AAS: How have weather and climatescientists stepped up in fighting cuts to federal agencies like the National Oceanic and Atmospheric Administration (NOAA) and others?
1) People are feeling the impacts of climate change and footing the bill The impending arrival of Danger Season is a stark reminder that climate change impacts are already devastating communities worldwide, intensifying many kinds of extreme weather events, driving sea level rise, and harming human health.
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.
Illinois Public Media recently premiered Weather Realness, a new weekly radio program and podcast in partnership with the Department of Climate, Meteorology and Atmospheric Sciences in the School of Earth, Society & Environment at the University of Illinois Urbana-Champaign.
Its not a genuine effort to engage with scientific facts and listen to climatescientists. After all, the President has called climate change a hoax and many of his cabinet are climate science deniers. This directive shouldnt fool anyone.
The news that started leaking last Friday is that the Trump administration wants to break up the National Oceanic and Atmospheric Administration and essentially end NOAAs climate work by abolishing its primary research office and forcing the agency to instead help boost U.S. Trump wants to Make Weather a Mystery Again.
Heres what else has happened in the last 7 days No Climate Assessment: The Trump administration has unceremoniously dismissed all the expert authors of the next authoritative look at how climate change is affecting the US.
You can imagine my surprise when upon receiving a request to speak at a 2022 Midcontinent Independent System Operator (MISO) meeting to consider how the entity might value the benefits of new transmission investments to avert power outages during extreme weather events, I learned that I was to be the first climatescientist to speak in this space.
Some reporters like Arcelia Martin at Inside Climate News drew the climate connection by the second graph, writing that climatescientists said the torrential downpours on July 4 exemplify the devastating outcomes of weather intensified by a warming atmosphere.
There has been comparatively less attention to the decision by climatescientist Dr. Susan Avery not to seek re-election to the ExxonMobil board of directors. Yet this shift in corporate leadership is significant, marking the end of a chapter in ExxonMobil’s long and ongoing history of climate deception and disinformation.
The rains were the result of a weather phenomenon known as an “atmospheric river,” a narrow column that transports water vapor from the tropics to the poles. Atmospheric rivers are projected to intensify as the climate continues to warm. Atmospheric rivers are not uncommon in the region.
This trend will continue as glacial melting, decreased rainfall, and a “thirstier” atmosphere jeopardize sources of freshwater in some parts of the globe. The Intergovernmental Panel on Climate Change, a group of the world’s leading climatescientists, released its sixth climate assessment on Monday.
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.
This week, Circle of Blue looks at a major new climate report, which finds that a warming planet is accelerating the water cycle. The Intergovernmental Panel on Climate Change, a group of the world’s leading climatescientists, has released its sixth assessment report. The report, while grim, does offer hope.
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.
Last year, I met Dave Schneider, a climatescientist who studies ice sheets and climate systems, work very similar to my own. that’s specifically about climate change and fossil fuel accountability. I checked out the science books, and there were some interesting titles but literally nothing about climate change.
“Optimism and hope are muscles we have to exercise,” climatescientist Rob Jackson says. His new book offers a paradigm for how to think about climate change and the health of the planet.
Warming of the surface of the Arctic is matched by a colder polar vortex high in the atmosphere, which is speeding the breakdown of the Earth’s shield against ultraviolet rays.
New research by Lawrence Livermore National Laboratory (LLNL) climatescientists and collaborators shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have underestimated global warming over the last 40 years. Read more →
The good news is that there are some initiatives on climate change adaptation which involve climatescientists such as the Infrastructure and Climate Network ( ICNet Global ). Such professional debates should include climatescientists, the adaptation community, and prac titioners.
Like other climatescientists, he knew from research papers and worldwide storm patterns that a warming atmosphere is thirstier and sops up more moisture from oceans and the land. By Judy Fahys A question has bothered climatologist Park Williams during the decade he’s been probing drought in the Southwest.
are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.
An “atmospheric river” has pummeled California with weeks of heavy rain, and the Rocky Mountains are getting buried with snow. Climatescientists, though, say the 40 million people who use the river’s water should take the good news with a grain of salt.
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. Organic aerosols are tiny particles that include dust, ash, and pollen.
We live in a world that markets individual action as the singular solution to climate change, instead of corporate and governmental accountability, where multinational companies and the governments that endorse them are largely responsible for the excessive carbon in our atmosphere. Seeing them come to life in court was powerful.
By Amy Green, Lisa Sorg Tropical Storm Debby, a plodding, waterlogged system that has already saturated four southeastern states, bears many characteristics of a warming planet, climatescientists say. It’s reminiscent of other catastrophic tropical cyclones that have battered the United States over the past eight years.
The state’s legendary and beloved “climatescientist-communicator” finds his public outreach isn’t valued by the institutions in America that fund science.
Corporate leadership was informed about advances in climate science and incorporated those advances when its scientists built their own models. Regardless, the company publicly cast doubt on the reality of global warming, attempted to discredit climatescientists and climate models, and tried to block climate action.
I hope we can collectively reckon with another terrifyingly awesome atmospheric event: the hottest year. Communities from Texas to Ohio that are benefiting from this scientifically informed tourism boom are the same places where some people like to question and mock climatescientists. as one writer put it on X.
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.
The Inflation Reduction Act is directing $20B toward climate-resilient agriculture Reducing heat-trapping carbon dioxide (CO 2 ) emissions through policies that drive renewable energy and clean transportation has well known benefits. This, in turn, can help lessen the price shocks that can result when crop and livestock losses occur.
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.
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.
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 →
