Weather Presenter Ross Hutchinson explorers if climate change is irreversible and is it possible for us to stop it
Our climate has already changed because of human activity and it is too late to reverse many of the impacts we are already experiencing. But there is still time to reduce or even stop future impacts.
We can still act to slow our changing climate and to avoid or limit some of the worst effects. Our actions today will have huge consequences for the future of life on our planet.
According to NASA scientists, if we immediately stopped emitting greenhouse gases global temperatures would stop rising within a few years.
It is thought they would then remain at that level for centuries, rather than dropping down to pre-industrialised levels. It means many actions we take today will be for future generations.
We, therefore, need to learn to adapt to our changing climate and limit how much further we allow temperatures to rise.
Here in the UK, records from the Met Office show the temperature has already warmed by 1°C since the 1950s.
The temperature increase can be observed in many ways:
Increased temperature in coastal seas around the UK
Less frost and snow
Longer and more frequent warm and hot spells
Shorter and less frequent cold spells
Breaking many high temperature records
At our current rate the Met Office predicts that, compared to our climate in 1990, by 2070 we will be seeing:
Winters a between 1 and 4.5°C warmer
Winters up to 30% wetter
Summers between 1 and 6°C warmer
Summers up to 60% drier, depending on the region
Hot summer days between 4 and 7°C warmer
All these changes would see increasingly difficult living conditions in many parts of the world. So although we cannot undo what we have seen so far - we need to act to stop further extreme changes in our climate.
