Global warming is, in my humble opinion, man-made. I mean if you think about it, the reason why we have it in the first place is our unrestrained pursuit of riches and advancement without due regard to environmental preservation.
5 million deaths a year caused by global climate related abnormal temps. The world's largest study of global climate related mortality found deaths related to hot temperatures increased in all regions from 2000 to 2019, indicating that global warming due to climate change will make this mortality figure worse in the future. The international research team looked at mortality and temperature data across the world from 2000 to 2019, a period when global temperatures rose by 0.26C per decade. Source 5a.
I'd respectfully disagree for the most part, I feel that we are simply going through yet another time in the existence of our planet that the climate is having a major shift. I would admit we might be contributing to it in a very small amount, however not to the degree as everyone concerned about it seems to think.
Has our distance from the sun decreased? A plausible reason as even a tiny shift in the earth's position could have drastic changes. Has the sun itself expanded at all, bringing it closer to us?

Study shows how 1.5°C temperature rise can cause significant changes in coastal species. As COP26 leaders gather in the UK, new research shows a temperature increase of around 1.5°C -- just under the maximum target agreed at the COP23 Paris meeting in 2017 -- can have a marked impact on algae and animal species living on our coastlines.

Warming oceans are getting louder. Climate change is speeding sound transmission in the oceans and the way it varies over the globe with physical properties of the oceans. Two 'acoustic hotspots' of future sound speed increases are predicted east of Greenland and in the Northwest Atlantic Ocean, East of Newfoundland. In these locations, the average speed of sound is likely to increase by more than 1.5% if 'business-as-usual' high rates of greenhouse gas emissions continue through 2100. Source 1h.
