The author has selected the most interesting physical discoveries related to the Earth's climate made over the past three years. Is it possible for our planet to transform into the hot hell of Venus, or into the icy, waterless desert of Mars? What physical evidence is there for global warming or a new ice age? Is it possible that the mammoths were killed by the physical phenomenon “methane hydrate gun”? In fact, for the first time in the school and university curriculum “general physics”, synergetic phenomena were introduced into consideration. In general, the material presented corresponds to the section of physics “thermal phenomena”. Designed for the most prepared schoolchildren and students. It can also be used by teachers to organize cognitive motivation of students.
