The statistics prove that climate change is a very real problem. Based on the rate of temperature Increase during the last century, we can predict that the overall temperature on Earth will be rising / will have risen by 3.4 degrees by the year 2100. This might not sound like much, but it could have a serious impact on our lifestyle. Let's fast-forward to the end of the century and imagine what life will be like …

• will be rising

• will have risen

In the year 2100, we'll have been eating / be eating less vegetables. How do we know this? Well, pests that attack plants normally don't like colder weather. However, if things heat up, then the frost-free season will extend, and this will cause significant damage to crops.

• have been eating

• be eating

It is also likely that in around 80 years' time, we'll be travelling / have travelled to work equipped with both sunglasses and an umbrella. In 2100, weather patterns will have become so unpredictable that we'll need to be prepared for every eventuality.

• be travelling

• have travelled

Then there are the oceans. If you live in a low-lying city like say, Bangkok, then in 2100, you will probably be living / have been living underwater. That's because sea levels are estimated to rise by 65 centimetres over the next 80 years. The worst-case scenario would be terrible for any place that is currently at sea level, so I wouldn't plan a holiday to the Maldives around then. In fact, you might want to avoid the Maldives from about 2050, because people there will be living / have been living underwater since then. We can joke, but in all seriousness, this issue is not going to solve itself.

• be living; be living

• have been living; be living

• be living; have been living

• have been living; have been living

It gets worse. By the year 2048, the international treaty to preserve our most important continent, Antarctica, will be expiring / have expired If this is not renewed, then the icy continent will be open to further tourism, development, business ventures and potentially destruction.

• be expiring

• have expired
