Organic aerosols from forests could help cool the planet

Physics World

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.

Plastic aerosols in the atmosphere could affect the climate

Physics World

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.

Climate-Fueled Extreme Weather Events Are Worsening. We Need Action at COP29

Union of Concerned Scientists

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.

Think climate change is messy? Wait until geoengineering

Environmental News Bits

Someone’s bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences, says climate scientist Kate Ricke. Read the full story in Wired. Read more →

Science denial is still an issue ahead of COP28

Real Climate

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.

Oscillating temperature gradient boosts heat flow in fluids

Physics World

The discovery by Ladislav Skrbek at Charles University and colleagues could help climate scientists 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

A Nobel pursuit

Real Climate

In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climate scientists. 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.
