We do not have any proven methods of climate engineering that would stop global warming; we must make better use of the Sun as a source of energy and change our habits if we want to survive, says atmospheric physicist Prof. Szymon Malinowski.
Technologies enabling the use of renewable energy have recently become much cheaper and their efficiency has improved. In the face of climate change, we should take advantage of them - Marcin Popkiewicz, an expert from the website "Nauka o klimacie" ("Climate Science") says in an interview with PAP.
Our current technology is completely unsuitable for travelling to the centre of the Earth. The temperature and pressure are so high inside the Earth that none of the known materials could withstand these conditions, says Dr. Mirosław Jastrzębski from the Institute of Geological Sciences PAS.
The white streak that the plane leaves behind it in the sky is simply a cloud of water droplets or ice crystals. It forms when hot steam from the engines liquefies, mixing with cold air at high altitude. Just like steam from a kettle - says cloud physicist Prof. Szymon Malinowski.
