Explanation:

IPCC Assessment Reports

The IPCC assessment reports have been extremely influential in directing the dialogue and action on climate change.

First Assessment Report (1990): It found that global temperatures have risen by 0.3 to 0.6 degree Celsius in last 100 years.

• This report formed the basis for negotiation of the UN Framework Convention on Climate Change in 1992.

Second Assessment Report (1995) - Global rise in temperature by 0.3 to 0.6 degree Celsius since late 19th century, “unlikely to be entirely natural in origin”.

• This report was the scientific underpinning for Kyoto Protocol in 1997.

Third Assessment Report (2001): It has predicts that by 2100, the sea level is likely to rise by as much as 80 cm from 1990 levels. Glaciers to retreat during the 21st century.

• Presented new and stronger evidence to suggest that global warming is mostly attributable to human activities.

Fourth Assessment Report (2007): Greenhouse gas emissions increased by 70 per cent between 1970 and 2004.

• The report won the 2007 Nobel Peace Prize for IPCC and was the scientific input for the 2009 Copenhagen climate meeting.

Fifth Assessment Report (2014): Rise in global temperatures by 2100 could be as high as 4.8 degree Celsius from pre-industrial times

• This report formed the scientific basis for negotiations of the Paris Agreement in 2015.

Sixth Assessment Report: It is attempting to provide more actionable information to help governments take policy decisions.

• It would likely state what the scenarios for sea-level rise in the Bay of Bengal region is, not just what the average sea-level rise across the world is likely to be.

Hence all statements are correct.
