I am a Physics teacher so as I tend to follow the reality of subjects and not what the press, politicians and social media want people to believe so that they can get the general public to hate each other for colour, gender, culture or race, (or for being a Manchester United supporter :).
Climate change IS with us now and anyone who is willing to spend just an hour at say John Moores science labs etc will go from a doubter to someone who realises that we have gone past the point of being able to do anything about it.
Even scientists on both sides of the argument who constantly argue with each other on climate change, all agree that our young children will witness around a quarter of all current wildlife and plants being wiped off the face of the earth by 2100. At the current extinction level which is doubling every year, almost all wildlife apart from remote areas such as Borneo, will be extinct and almost half of all current living vegetation by 2200.
The current trajectory of global sea temperature can be mapped quite accurately so we know that by 2100, large swathes of London will be under the tide limit, resulting in areas such as Richmond being lakeside areas.
Low flat water inlets such as the North West coastline will see places such as Merseyside, Blackpool and Southport also UNDER the tideline with the estuaries around all coastal regions swallowing many coastal towns and villages.
The temperature of the North Atlantic is warming much faster than the most fearsome predictions which will result in a different type of UK weather by 2100 which will be similar to current weather patterns in West Asia, monsoons etc and long arid summers.
If anyone thinks "well this summer is a washout so there is no global warming, then that is folly as this is EXACTLY what was predicted as alterations of global high and low pressures is the result of a climate shift.
So to answer the question, no I don't think you should be worried about your husband being unconcerned as 99.9% of the public do not have enough information to make a judgement so that does not make him a bad person.
For people saying all climate change believers are 'woke, you really need to research where the word woke came from and what it REALLY means and its not what bigots thinks it means :)
