From NOT A LOT OF PEOPLE KNOW THAT By P Gosselin on 26. November 2021 Die kalte Sonne reports on a new aerosol study by Liu et al. The results are a major blow to…

Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction “Hampering Climate Change Projections”

By acting as cloud condensation nuclei (CCN), aerosols act as cloud condensation nuclei and thus can alter cloud properties and precipitation. This influences the Earth’s radiation budget and hence climate…

Aerosol formation in clouds

“Our experimental setup allows us for the first time to precisely investigate the distribution of organic vapours at the air-water interface under near-environmental conditions,” says Houssni Lamkaddam, a researcher in…

COVID-19 lockdowns temporarily raised global temperatures

The lockdowns and reduced societal activity related to the COVID-19 pandemic affected emissions of pollutants in ways that slightly warmed the planet for several months last year, according to new…

The natural ‘Himalayan aerosol factory’ can affect climate

“To understand how the climate has changed over the last century we need to know as reliably as possible the natural atmospheric conditions before the industrialization,” says Associate Professor Federico…

Does Universal Mask Wearing Decrease or Increase the Spread of COVID-19?

A survey of peer-reviewed studies shows that universal mask wearing (as opposed to wearing masks in specific settings) does not decrease the transmission of respiratory viruses from people wearing masks…

Ships’ emissions create measurable regional change in clouds

A container ship leaves a trail of white clouds in its wake that can linger in the air for hours. This puffy line is not just exhaust from the engine,…
