Are the global climate changes cause for alarm?

I have been reading Climate Courage by Andreas Karelas upon finding it at a bargain store. This matter of global warming I had come to believe was something which has been blown out of proportion by the media. Could it be a collective hallucination that human industry is causing all these environmental changes? I have a feeling many want to deny the harmful effect humans have on the environment as it's too much of an inconvenience for them to think otherwise. On the other hand, I have been persuaded that some environmentalists are fabricating information to create a sense of alarm. Carbon dioxide has been this great obsession when it's not truly a toxin and I have yet to see any clear evidence that it's worthy of all the media attention and alarmist propaganda about how it's harming the global environment.

At the very least, you have to admit that the climate is changing. Here in Britain, we still have our cold winters, which our homes are built to withstand - we have central heat... but we are also having hotter summers.

Our homes are not designed for the extreme heat that we're getting - and opening the windows is counter productive when the heat outside is akin to turning the oven on and opening the door.

Without intervention, people are going to die because they overheated or dehydrated. We've had a/c for decades now... yet, only some private households have been retrofitted with this technology - and certainly not many rental properties where our elderly and disabled live... people who might struggle to breathe and look after themselves in temperatures over 30 degrees.

Many work places do have a/c and most working age people can benefit from that during the hottest part of the day, even if it does mean letting the subcontractor working on the roof inside for his breaks so that he can cool down out of the heat - but, what about the elderly and disabled???
