Translation

When I enrolled in Math 202, I anticipated difficulties because I was not well grounded in mathematics in high school. The course was taught by Professor Richardson, a fine specimen of an old-fashioned gentleman, very cordial to his students. However, when it came to academic matters, he was by no means an easy person. Before he started his lecture, he discoursed enthusiastically on the importance of working in an orderly fashion, of being thoroughly prepared before each class, and of not being content with what you have learned. His attitude towards work was infectious, and by and by I became an ardent math lover, too.

Translation

Most scientists no longer doubt that the world is warming up and that humanity has altered climate. They agree that the long-term effects of global warming will be disastrous for the planet and its inhabitants. What is more, climate change won't be a smooth transition to a warmer world. Some regions will be greatly affected by abrupt climate changes. Enormous areas of densely populated land like coastal Florida would become uninhabitable. Hundreds of millions of residents would have to migrate to safer regions. Therefore, it is no surprise that global warming has made its way onto the agenda of world leaders.
