When a picture says more than 100 words Here you can see the height of the pole showing how many vertical meters the alpine glacier has lost during this summer Melting glaciers does not only mean the retreat of the area where they are located, but also thinning It won't be long before alpine glaciers cease to exist. (translated)

Dengue fever is successfully spreading to the north. To places where it was not a few years ago. We should be worried about the increases in cases in Spain, France, and Croatia, where mosquitoes are already infected. A nice example of what a few tenths of a degree Celsius more can do. (translated)

Massacre, what all AI can do. I’m making a presentation for a conference on the popularization of science... and a few prompts, pouring in some input data, two to three hours of interaction... And I’m blown away... Once again, I marvel at what is possible to create with it. Here you have the final presentation https://t.co/suwzTllCCF (translated)

Unfortunately, it is confirmed what was clear from the footage - that there will be many victims - the death toll is approaching one thousand, and there are more than 4,200 missing... (translated)

Satellite images captured by the Landsat 9 probe nicely show how a large piece of Nepal's glacier collapsed yesterday in an instant. It then headed into the valley, where it descended about 1200 meters in elevation in a short time, gaining considerable energy. A still unclear question (translated)

What caused the devastating flood wave in Nepal? It looks like a glacier collapse... (translated)

By the way, if it is confirmed that the flood was caused by the collapse of a glacier, we can attribute it to global climate change, which destabilizes the Himalayas (just like most other parts of the planet) due to rising temperatures. It won't be the last time we see something like this. (translated)

This tweet contains a video of a helicopter flying over a river valley that has already been swept by floods. It is completely transformed, and it is clearly visible how high the wave was able to reach. It is certain that the number of victims will be significantly higher. (translated)

CNN reports that according to Nepali authorities, the flood may be caused by an earthquake. A landslide occurred that temporarily blocked the local river. I currently do not understand how such a massive flood wave could have been caused by this - whether it triggered a lake tsunami or if a dam broke? We'll see. (translated)

The number of victims will certainly be much higher - this is truly a massacre. In an instant, a wall of water and debris arrived, taking with it everything it encountered. (translated)

In Nepal, there was a flash flood (likely) caused by an earthquake in one of the local valleys, which triggered a landslide of rocks and ice into the local river... There are approximately twenty dead and many people are missing. In front of this person, there is no chance to escape... (translated)

As the almost dreamlike scene of the tornado presented itself to the residents in the southwest of France... A terrifying beauty that I would definitely forgive not seeing with my own eyes... (translated)

After more than 20 years of preparation, NASA is preparing to send the Dragonfly probe to Titan; one of the most interesting worlds in the solar system. Why is it going there? What have we learned about it thanks to Cassini and Huygens? Want to know more? Then check out YouTube after 7 PM. (translated)

... for the green landscape to turn into a wasteland. The change in the ecosystem does not have to occur slowly; it can happen suddenly. Nature does not mind; it can cope with it - it has time for that. It bothers us. A species that has built a civilization on the assumption that the world does not change too much. (translated)

However, it actually takes very little for the world around us to change. Global climate change, which we significantly enhance with our activities, creates suitable conditions for that change to be abrupt. It is enough to change wind currents and thus the distribution of precipitation... (translated)

Main pages of newspapers to the west of us. Fires linked to extreme drought devastating parts of the continent are raging in France and Spain. And even though part of the political representation here pretends that nothing is happening, we are not fooling ourselves. It is only a matter of time before it hits us too. (translated)

It is worth reminding the phone number 116 123 for the First Psychological Aid Line, or possibly further contacts on this website. Don’t be alone in the toughest moments. (translated)

Lottie Williams experienced something incredible - she survived a hit by space debris! (translated)

After more than twenty years of preparation, NASA is about to launch the Dragonfly mission to Titan – a probe powered by a radioisotope generator (RTG) that will fly between dozens of locations on the surface of Saturn's largest moon with the help of eight rotors. Its main goal will not be the search for life. (translated)

Have we found traces of extraterrestrial life on Mars? (translated)
