Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

In that year, El Nio added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat. Albedo is the total reflection of incoming solar radiation by Earth. This question was a focus at the 2024 annual American Geophysical Union (AGU) meeting in Washington, D.C.,

The Politics of Geoengineering Are Getting Stranger

Legal Planet

For example, the core provision of the Tennessee law : The intentional injection, release, or dispersion, by any means, of chemicals, chemical compounds, substances, or apparatus within the borders of this state into the atmosphere with the express purpose of affecting temperature, weather, or the intensity of the sunlight is prohibited.

Solar Orbiter Captures the First-Ever Images of the Sun’s South Pole

Scientific American

The smaller views show light coming from charged gas in the sun’s atmosphere at different temperatures. But as the sun spins, the roiling plasma generates sunspots, dark, relatively cool patches on the sun’s surface that are looping tangles of magnetic field lines.

The enigma of Trappist-1 b: a thick atmosphere or airless rock?

Physics World

Located about 40 light years from us, the exoplanet Trappist-1 b, orbiting an ultracool dwarf star, has perplexed astronomers with its atmospheric mysteries. and 15 µm), suggest that the exoplanet could either be bare, airless rock like Mercury or shrouded by a hazy carbon dioxide (CO 2 ) atmosphere like Titan. µm refuted this model.

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

As predicted in 1967 by Manabe and Wetherald , the stratosphere has been cooling. The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. But why is the stratosphere increasingly chill? The basic concept is easy to grasp though.

Can Life Survive the Death of the Sun?

Scientific American

This warming is mostly from natural greenhouse gases, mind you, but we’re adding approximately 40 billion tons of carbon dioxide into the atmosphere every year , significantly increasing the warming effect. On top of that, our planet will lose its atmosphere to space when it gets this hot as well. Our oceans will evaporate.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium.
