Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

Last month, 44 climate scientists 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!

Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

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. Albedo is the total reflection of incoming solar radiation by Earth.

What Is a Climate Model and How Does It Work?

Union of Concerned Scientists

Climate models are the main tool climate scientists 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.)

How Do ‘Future Climate Scenarios’ Shape Climate Science and Inform Policy? 

Union of Concerned Scientists

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.

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.

Real Climate

As climate scientists 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!) 1981) which can be seen here.

New Climate Research From a Year-Long Arctic Expedition Raises an Ozone Alarm in the High North

Inside Climate News

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.
