Ледник — это масса льда преимущественно атмосферного происхождения, испытывающая вязко-пластическое течение под действием силы тяжести, принявшая форму потока, систему потоков, купола или плавучей плиты. Наука, изучающая ледники, называется гляциологией. Рассказываем об образовании ледников, ледниковой археологии и влиянии таяния льда на климат.

While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care.
