Of the need to secure a future for our planet, and our children who will live here, there can now be no doubt that drastic action needs to be taken.

That's why news that Boris Johnson will accelerate plans to ban the sale of new petrol and diesel cars by 2035 should be welcomed.

We already have the technology. No matter what car manufacturer you favour, they already sell electric alternatives and by 2035 these will have far better mileage than they do now.

There will be some who resist this change - they may not believe in the science, or they may just love combustion engines - but hopefully they will remain a minority.

The science is now irrefutable - climate change deniers have been relegated to the fringes of the scientific community, along with vaccine sceptics, people who believe that the earth is flat and those who are convinced that the Royal Family are secretly reptiles.

Climate change has always happened, over millennia, and C02 levels have risen and fallen - but the current level of atmospheric C02 is now higher than it ever has been over the last 800,000 years, and is a direct consequence of human activity.

Missing out on the way a petrol car accelerates, or the smell of diesel, is a small price to pay for securing a future for our children.
