You know how hospitals are huge contributors to carbon emissions? Well, let's zoom in on surgical care, a major part of the problem. This study is all about finding out where the most carbon comes from in surgical care and why. Researchers used a tool called the Congruence Model to understand these
At a recent climate conference in Baku, countries agreed to increase climate finance for poorer nations to $300 billion annually. This new target replaces the previous goal of $100 billion per year by 2020, which was met two years late. The agreement is seen as a way to keep the clean energy boom gr
Air pollution, especially PM2. 5 particles that can cause serious health issues, is a major global problem. Knowing where to place sensors to monitor this pollution is a big challenge. It's like trying to find the best spots in a huge city maze, considering things like traffic, population, and weath
You might not think ozone, which is usually talked about in the context of Earth's protective layer, would affect rainfall and wildfires. But scientists have found a surprising connection in West Siberia. Over the past few decades, changes in summer rainfall have greatly influenced wildfire activity
Did you know that some herbicides can have a big impact on our water plants? We're talking about stuff like indaziflam, sulfentrazone, clomazone, and tebuthiuron. These chemicals were tested to see how harmful they are to two common water plants, duckweed (Lemna minor) and water ferns (Azolla caroli
Imagine trying to fix a global problem like climate change. One of the biggest issues at the recent climate summit was money. Rich nations offered $300 billion towards the $1. 3 trillion needed, but they wanted the rest to come from private investors and new taxes. Countries that are less wealthy di
Ever wondered how tiny pieces of rock from a gold mine can cause big problems? In Tanzania, waste rocks from gold mining are a real headache. Scientists tested different sizes of these rocks - from little ones smaller than a pea to big ones like a chicken egg. They found that tiny rocks can make the
COP29 brought together people from 200 countries, all hoping to make a difference on climate change. But the conference ended in gridlock, with the huge challenge of finding money to fight climate change looming large. Wealthy nations only pledged $250 billion by 2035, while poorer countries needed
Electronics are piling up, and so is the waste they create. This waste, known as e-waste, contains precious metals like gold that are often lost. Scientists have come up with a clever solution: a light, spongy material called aerogel. This material is made by combining two types of compounds and has
At the UN climate summit in Baku, Azerbaijan, a new draft deal proposed $250 billion annually for poorer nations to fight climate change. This amount, twice the previous goal, is seen as too low by developing countries who are hit hardest by extreme weather. The rich nations, however, argue it's the
