The 29th Conference of the Parties on Climate Change (COP29) is starting today in Baku, Azerbaijan. This week, like every year, scientists, economists, and politicians gather to discuss how to solve the ongoing climate crisis. The goal of this conference is to keep acting on reducing greenhouse gas emissions, caused mainly by the use of …
There is a question that worries climate scientists a lot: will global warming stop when we reach zero greenhouse gas emissions? There are two schools of thought on this matter: the "optimistic" one claims that when (and if) we reach net zero emissions of greenhouse gases (CO2, methane, N2O, CFC, …), the long-term increase in …
Imagine a boundless stretch of ice. Picture it in your mind. Smooth, dazzling, seemingly eternal. Something happens, though. The ice begins to break, endangering the unfortunate protagonists on the ice sheet. If you thought about the opening scene of "Ice Age", you almost got it right. Instead of an adorable prehistoric squirrel and his beloved …
The pestiferous child modulating the earth's climate, together with his little sister. One of the most powerful climatic phenomena occurring on planet Earth. We are talking about El Niño (the child, in Spanish) and its counterpart La Niña. It’s making the headlines again because the Australian meteorological office has finally announced that an El Niño …

The latest is about the ice mass now called A-81, which detached from the Brunt ice shelf in Antarctica. The event was captured by the ESA satellite Sentinel-2, also letting experts to monitor all the stages of formation and widening …

This last Summer was difficult in terms of extreme events around the world. Let’s start from our home country. After a months-long drought, on the evening of the 15th of September the Marche region was hit by a self-regenerating storm, a very dangerous type of weather phenomenon, characterized by its ability to feed itself and …
In another post, I have summarised the history of climate change in our planet's remote and recent past. What can we say about the future? To answer, we must first understand how difficult it was to understand the role of atmospheric constituents (like the famous greenhouse gas) in the radiative balance of the Earth's atmosphere, …

It is clear now: the earth's climate is changing and it is causing a rise in average global temperature. It is still difficult to say how and how much global warming will affect our lives. Meanwhile, we can take a look at what has happened in our (more or less) recent past to understand the …
