3. what is the evidence presented as evidence to confirm climate change

As explained below.

Explanation:

There are lots of evidence that support climate change such as the evidence of glacial retreats and global fluctuation in ocean salinity. Apart from that, there are major changes like the global coral bleaching changes in patterns of trade winds and shifting of the ITCZ zone also. The changes can be seen in global climate related to the shift in polar to tropical and shift from tropical to subtropical climates also the rise in 1 to 3 degrees of temperature over the large bodies of oceans and seas has caused increase in acidification and salinization of freshwaters by the rivers and partly due to harmful activities of man in his environment. Thus these processes confirm the impact of climate change taking place on earth landscape.
