Global warming is happening now, and scientists are confident that greenhouse gases are responsible to understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate. Q: what is global warming a: here's a simple definition of global warming (and yes, it's really happening) over the past 50 years, the average global temperature has increased at the fastest.
Short answer: yes even a seemingly slight average temperature rise is enough to cause a dramatic transformation of our planet. Global warming research learn about the causes and effects of global warming consider possible global warming solutions read predictions of rising sea levels, coral reef bleaching and mass.
Global warming definition is - an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution. Global warming — the gradual heating of earth's surface, oceans and atmosphere — is one of the most vexing environmental issues of our time.
