The scientific view is that the increase in global temperature should ...
The scientific view is that the increase in global temperature should not exceed 2 degrees Celsius above pre-industrial levels. This threshold, often referred to as the "2-degree target," has been widely accepted by the international community as a critical limit to avoid catastrophic consequences of climate change.

The target was initially proposed by the scientific community and gained significant attention after being endorsed by the United Nations Framework Convention on Climate Change (UNFCCC) in 2010. It was later reaffirmed in the Paris Agreement, signed by nearly all countries in 2015.

Exceeding the 2-degree limit could lead to severe impacts, including more frequent and intense heatwaves, extreme weather events, sea-level rise, biodiversity loss, and disruptions to ecosystems and human societies. It is crucial to limit global warming within this threshold to minimize these risks and safeguard the well-being of both present and future generations.

Efforts to combat climate change focus on reducing greenhouse gas emissions, transitioning to renewable energy sources, promoting energy efficiency, and adopting sustainable practices in various sectors. These actions aim to mitigate the causes of global warming and limit temperature increase to a manageable level.

The scientific view is that the increase in global temperature should ...
Explanation: Impact of rise in temperature above 2 degree from pre industrial levels:

Hence statement 1 and 2 are correct. Statement 3 states that all the global wetlands will permanently disappear, which is an extreme statement and can be eliminated easily.
Similar to statement 3, statement 4 is also extreme which says cultivation of cereals will not be possible and can be eliminated.
Educational Objective: Understand the impact of Global warming and climate change.
