Guest Essay: PA Conventional Oil/Gas Operators Blog: More Carbon Dioxide Is Good, Less Is Bad

PA Environment Daily

People should be celebrating, not demonizing, modern increases in atmospheric carbon dioxide (CO2). In other words, the Earth came within 30 ppm in CO2’s atmospheric concentration of witnessing the extinction of most land-based plants and all higher terrestrial life-forms – nearly a true climate apocalypse.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

Science denial is still an issue ahead of COP28

Real Climate

It is 33 years now since the IPCC in its first report in 1990 concluded that it is “certain” that greenhouse gas emissions from human activities “will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.”

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

Planets in Alpha Centauri could be carbon-rich – if they exist

Physics World

Planets orbiting the Sun-like stars of Alpha Centauri could be carbon-rich worlds with diamonds and graphite littered across their surfaces, say astronomers. Carbon world. Within our Solar System, for example, the carbon-to-oxygen (C/O) ratio is 0.5, meaning that there are twice as many oxygen atoms for every atom of carbon.

Methane emissions rose in 2023 despite reduction initiatives

A Greener Life

By Anders Lorenzen The emissions from methane , a powerful greenhouse gas (GHG) with 80 times the warming potential of carbon dioxide (CO2) rose in 2023 despite several pledges and initiatives to reduce emissions. Graph credit: IEA.
