How studying clouds can improve climate models

How studying clouds can improve climate models by Elise Gout |November 23, 2022 Associated researcher Kara Lamb grew up reading his father’s American Scientist magazines. She absorbed everything she could about quantum physics and for a time thought she would study it for the rest of her career. But in 2008, after Lamb completed his […]

How well do state-of-the-art climate models simulate sea level?

According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, global mean sea level has risen faster since 1900 than in any previous century in the past 3,000 years. This leaves hundreds of coastal cities and millions of people vulnerable to a threat from higher water levels. State-of-the-art climate models provide a […]

Climate models can more accurately simulate atmospheric conditions by including vapor buoyancy

UC Davis researchers determine lightness of water vapor should not be excluded from climate models By LILLY ACKERMAN — [email protected] A recent study researchers from the Department of Earth, Atmospheric and Aquatic Resources at UC Davis determined that the lightness of water vapor in the atmosphere has significant impacts on clouds and temperature, and should […]

Exploring AI solutions for climate change

AI has already had a substantial positive influence in the fight against global warming. However, quantifying its importance and characterizing its effects remain open issues. This article provides an overview of initiatives and projects leveraging AI to understand and combat climate change, highlights existing research documenting the potential positive impact of AI on climate change, […]

Climate models could help predict future disease outbreaks

Numerous studies over more than two decades have demonstrated a strong relationship between climate and the dynamics of human diseases, such as cholera, malaria and dengue fever. Changes in climate, including long-term warming trends and short-term climate variability, could affect disease patterns. Xavier Rodó, computational ecologist and specialist in climate dynamics at the Institute of […]

How population growth and climate change are linked | New

PA At first glance, the links between global population growth and climate change seem obvious. The more people we have on this planet, the greater their collective impact on the climate. However, closer examination with a longer time horizon reveals relationships between population size and climate change that may help us better understand humanity’s plight […]

Rapid rain squalls are intensifying and climate variability cannot explain it

Powerful, short-lived rainfall events in Sydney are intensifying to new extremes, increasing by 40% over the past 20 years, new research shows. The results, published in Science, suggest that extreme sub-hourly rainfall could be increasing much faster than previously thought. Rapid rain squalls, also known as “intra-hourly heavy rain,” are the most extreme and destructive […]

Fight climate change with the cloud by your side

The Covid-19 pandemic is a cruel reminder that even on the 21st century, our world is just as vulnerable to crises as it was in the early days of human civilization. There is no crisis more serious than climate change. Anant Adya, Executive Vice President of Infosys Cobalt, says if we hope to stop the […]

The United States should lead by example in the fight against climate change

Letters A recent letter to the editor caught my eye. The author was talking about problems for voters. He mentioned inflation, certainly a big problem, although it is a global problem. He also mentioned another global issue, climate change, and said policymakers should recognize that developing countries were not going to ban fossil fuels, but […]

IPCC’s climate change mitigation scenario is inequitable, pre-COP27 study finds

The scenarios envisaged by the Intergovernmental Panel on Climate Change (IPCC) to keep global warming below 2 degrees Celsius are highly inequitable, as rich countries will continue to occupy the largest share of the carbon budget, said a new guidance document released days before the UN conference. climate change summit, COP27, which opened on Sunday […]

Can extreme climate events be attributed to historical emissions? Krishna AchutaRao explains

Krishna AchutaRao, a professor at the Center for Atmospheric Sciences, talks about what modern attribution science can say about loss and damage as well as historical responsibility Until a decade ago, extreme weather events could not be attributed to human activity. But that has changed now. Climatologists can now assess how the frequency and intensity […]

We need to improve climate models to make better policies

Representative photo: Chris Liverani/Unsplash As COP27 approaches, the spotlight is once again turning to crafting a compelling national narrative on climate change – based on what India can do and what India needs. There are many independent estimates of India’s needs, ranging from $1 trillion to invest over the next decade to $10 trillion needed […]
