Last time, I expressed extreme disappointment that fossil fuel executives had any role in leading the climate meeting COP28. This is a classic example of putting the the fox in charge of the hen house. The issue is easily summed up: Setting aside economic self-interest and other human foibles, it is clear from the comments that the science is not as clear to everyone as it is to me. That’s fair;

In 1986, I was a grad student at Princeton, working in the atomic physics lab of Will Happer. It was at a department colloquium that I first heard a science talk that raised serious concerns about our use of fossil fuels potentially impacting the climate. This was not received well. People asked all sorts of questions, with much of the discussion revolving around feedback effects.

Biodiversity and Climate Change Biodiversity is the variety of all living organisms on Earth, from plants and animals to microorganisms. It is an essential part of our planet’s natural systems and provides numerous benefits such as food, medicine, and ecosystem services like pollination and soil health. However, biodiversity is under threat from various human activities, including climate change.

Polar bears are one of the species most affected by climate change. The primary reason is that their habitat, sea ice, is rapidly declining due to rising global temperatures. As the sea ice melts, it becomes more difficult for polar bears to hunt for their primary food source, seals, and as a result, their populations are declining.

Climate change is a pressing issue that is affecting various species across the globe. One of the most affected species is birds, particularly those that migrate. Bird migration is a natural process where birds travel to different locations for breeding, feeding, or overwintering. The changes in the Earth’s climate have caused significant disruptions to these patterns, causing serious implications for bird populations.

Acid rain is a term that refers to a mixture of wet and dry deposits (deposited material) from the atmosphere that contains greater than normal amounts of nitric and sulfuric acids.

Happy World Ocean Day! World Ocean Day is a day of celebration and action to protect our shared ocean. While I already appreciate the importance of protecting sensitive ecosystems, including the ocean ¹ , I found the idea of World Ocean Day especially touching.

I have had the misfortune to encounter many terms for psychological dysfunction in many venues. Cognitive dissonance, confirmation bias, the Dunning-Kruger effect – I have witnessed them all, all too often, both in the context of science and elsewhere. Those of us who are trained as scientists are still human: though we fancy ourselves immune, we are still subject to the same cognitive foibles as everyone else.

I’ve recently released the new package ccafs, which provides accessto data from Climate Change, Agriculture and Food Security(CCAFS; http://ccafs-climate.org/) General Circulation Models (GCM) data.GCM’s are a particular type of climate model, used for weather forecasting,and climate change forecasting - read more athttps://en.wikipedia.org/wiki/General_circulation_model.
