It is believed that increasing amounts of greenhouse gases in the atmosphere will result in
Jobisdone [24]

"Belief" is not involved.  

<em>Choice-A</em> is the correct answer. Except that it's not "... will result in ...".  It's already happening.

The people who have been keeping records of temperatures at a thousand places around the world, for the past hundred years, do not "believe".  They know that average global temperatures are increasing, and have been increasing steadily for a couple of Centuries now.

Working from hypotheses, models, observations, and proven laws of nature, the global scientific community are convinced that increasing amounts of greenhouse gases in the atmosphere, driven by human activity, are the cause of the trend in average global temperatures.

Yes, you can find published researchers who aren't so sure, and who disagree with this conclusion.  The scientific community is <em>never</em> 100% unanimous.  There were reasonable investigators and scientific observers who disagreed with Galileo, Newton, Faraday, Maxwell, Hawking and Einstein, in their time.  

But the voices that dispute human-caused climate change in the form of global warming are few, and they're becoming fewer as time goes on. Today, their reputation sits just a few notches above that of the Flat-Earthers, and it's continuing to sag further.

If we are to do what has to be done, in time to bring about the needed effect, it can't sag fast enough.

What are the Characteristics of the taiga
Natalka [10]

Answer:

A biome that is also known as the snow forest or boreal forest is called the taiga forest. This forest is characterized by the presence of the coniferous tress.

Explanation:

  • It is the largest known biome and is known to contain the soil that has negligible nutrient content and high acidic content.
  • The limit in the organic contribution of the soil is mainly due to the cold and moist climate that does not undergo deterioration for longer period of time. Also, it adds to the thinness of the soil.  
  • Accompanied by the coniferous trees, the vegetation includes broad leaved trees and some herbaceous plants.  
  • The climate consists of longer winters and smaller summer season. Mammals, fishes and insects are present in the taiga forest along with the herbivores mammals.
