  • From bbclearningenglish.com Hello and welcome to Six Minute English, I'm Alice.

  • How do I'm Neil?

  • I'm feeling a bit chilly today, Alice.

  • Mmm, yes, it is unseasonably cold today.

  • Which means not normal for the time of year.

  • But the weather is very unpredictable these days.

  • Mmm, I know what you mean.

  • Global warming is the subject of today's show.

  • Is global warming really something to worry about?

  • Some people say that the earth has warmed up in the past and nothing terrible's happened.

  • The earth has warmed up before,

  • but this was the result of things like wobbles in the earth's orbit,

  • not because of an increase of greenhouse gases in the atmosphere.

  • Can we reverse the changes?

  • No, it's too late.

  • And now we have to find ways to adapt to extreme weather,

  • rising sea levels and melting polar ice caps.
