Presumably we should be more concerned about global cooling as about global warming. The industrialized world has the means abundantly. I proved it with my book about the impact of naval war during the Second World War 1939 to 1945, https://www.seaclimate.com/ , which caused a global cooling from 1939 until about the mid-1970s. Although this cooling period was significant, as mentioned above, science is still not able to offer a convincing picture on why the three decades cooling period happened. The seas and oceans reaction to human activities, by means of naval war, caused it.
