"in a 2009 study, presented by the national academy of science, 97% of climate scientists agree that human activity is
causing global warming." which of the following statements is best supported by this study?
a most climate scientists dispute the theory of human influence on global warming.
b. global warming is most likely alarmist propaganda based on false data.
c. global warming is definitely not caused by human influence on nature.
d. most climate scientists believe that there is evidence that explains global warming.
select the best answer from the choices provided

The correct option is D)  Most climate scientists believe that there is evidence that explains global warming.

Explanation:

There is a strong scientific consensus which tells that human activities are causing a change in the climate and global warming has arisen due to the activities of the humans.

Many scientists have provided evidence which explains how the activities of the humans are causing global warming. Nearly all climate scientists i.e 97-98 percent believe that human activities are causing this climate change.

The climate scientists claim that greenhouse emissions have caused the most global warming.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
