The issue of climate change has been growing for a number of years now and you will certainly find quite a bit about it online.
The current buzz phrase is "carbon footprint" - your carbon footprint is the amount of greenhouse gasses you and your lifestyle produce in a year.
And if you have been wondering just exactly how much that is, you can work it out on the web.
There are many carbon footprint calculators around, and to be honest I think they are all far too simplistic to give you an accurate reading. I have certainly got many different results.
But being aware is one step and this calculator on the BP website has caught my eye.
It is a flash-based site with little pictures which illustrate your lifestyle as you enter details about it.
Your country, type of accommodation and the number living there are all important, so you enter them first.
Then as you continue to tell the calculator all about your home, your lifestyle, and how energy conscious you are, you can see the graphs at the top of the screen begin to grow.
I found myself almost not wanting to look as I entered my details.
But it was when I started detailing my travel for the past year that things really started to get embarrassing - you can see just how much CO2 the various methods of transport generate.
At the end of the process, you are given your carbon footprint - the number of tonnes of CO2 you generate in a year.
You are also told how you compare to your country's average.
Click "What you can do" and "Quiz" on the left of the site and you will find suggestions on ways you can cut down your CO2 emissions.
As I say, there is loads of carbon footprint info all over the web - read, digest, calculate and then of course it's up to you to decide what to do about it.
