Final answer:
The evidence of climate change indicates a significant increase in global temperatures and a decrease in ice formations such as glaciers and sea ice. Hence, the correct option is (b).
Step-by-step explanation:
According to the evidence of climate change, there has been an overall increase in ocean and land temperature, and an overall decrease in ice formations. Direct evidence for global warming comes from measurements of global land and ocean temperatures, which show a warming trend since the late 1800s, complemented by the shrinking of glaciers and decrease in Arctic sea ice and snow cover in the Northern Hemisphere.
Future climate change is also predicted to differ from region to region, with warming being greater over land and in the Arctic. Addressing global warming requires international cooperation to reduce greenhouse gas emissions, transition to renewable energy sources, and adapt to the changes that are already underway. Efforts to combat global warming are a crucial aspect of broader climate change mitigation and sustainable development goals.
