Temperature is driven by a variety of sources, primarily solar irradiation, but also greenhouse gases, ozone, volcanic activity, sulphates etc.
In the last 100 years greenhouse gases have been responsible for a temperature increase of 0.7 degrees, solar irradiation by 0.2, ozone by about 0.08, volcanics by -0.15 and sulphates by -0.25.
Currently La Nina and solar irradiation is a cooling effect. But temperatures are still increasing.
Contemporary global warming is caused by human action.
When you see the words 'journalist'...'environmental activist' and 'climate consultancy firm' together in the same paragraph you should also hear alarm bells in your head? Also, the usefulness of a degree in history and politics (political history?), in relation to climate, is about as useful as asking a biologist to explain quantum physics!
Global warming and climate change are real.
Caused or altered by man? No, that's just plain ridiculous...!
If the sun goes quiet as it has done regularly in the past, then we will be 'plunged' into an ice age which 'really will' wipe out most life on earth. Famine would wipe out billions of people in a matter of a few months. This scenario is GUARANTEED to happen again and we can't accurately predict when, but when it does, we won't need to wait 100 years for it to occur.
