Anyone can make images like that. I could even make them myself. Please don't be so naive.
The Global temperature goes up and down in cycles. The last low (known as the mini ice age) was in the early 1800s when people camped out and ice skated on the Themes in London. It's been rising since then till it maxed out in 1998 and has been declining since then.
That's why the winters have been getting colder with more snow and ice every year. Where is all this extra heat and sea level rises melting ice caps etc.? I haven't noticed them. Have you?
