Agriculture emits greenhouse gases, but less than using fossil fuels, despite recent paper’s claim
A paper used unusual accounting methods by looking only at gross emissions and omitting CO2 sinks through reforestation; climate scientists explain that this method is misleading. It is like evaluating the status of your bank account based only on your income without looking at your expenses.

Do renewables increase the price of electricity? Not necessarily
Adding more solar and wind can increase the price that homes pay for electricity. But energy type is only one piece of the puzzle, and simply because a grid has more solar or wind does not mean it is more expensive.

Global warming doesn’t mean everywhere is warming at the same rate, here’s why
Global warming may mean something different than you think. One misconception is that global warming means ‘all places on Earth are warming equally’, but this is not the case. In reality, global warming means that average global temperatures are rising over decades or more. Earth’s uneven heating means that some places warm faster or slower than the average global temperature rise over a given period.

Cold snaps during global warming are not actually a paradox, here’s why
Why do cold snaps happen if the Earth is warming? Cold snaps are part of Earth’s natural climate variability. However, global warming is causing winters to get warmer, and making cold snaps less frequent or less intense over most land areas globally since 1950.

Training and using ChatGPT uses a lot of energy, but exact numbers are tricky to pin down without data from OpenAI
As the capabilities and adoption of artificial intelligence (AI) continue to grow, so are its energy impacts. Training and ongoing use of AI models requires significant energy due to their use of data centers – one of the most energy-intensive building types.
