Can some read the paragraph below and check my grammars are correct.

In the article Grim Climate Predictions Not Exaggerated, Analysis Says, John Roach bases on the study of The Science, John Roach reports that in the recent years the concentration of green house gas has almost similar to the projection of the 2001 IPCC report. In addition, The Science claimed that the IPCC might have underestimated few climate threats during 2001. IPCC report the emission of the protective greenhouse gases that make earth habitable is changing, resulting in current changes in climate and possibly environmental and societal. However, Rahmstorf argues that the report of IPCC is incomplete and failed to include the instability of ice sheet from the artic, which affects sea level. Steffen claimed that rising global temperatures tremendously affect the rising of sea levels through the melting of glaciers. Moreover, based on the newest ice observation, he stated that IPCC’s sea level predictions are too conservative.
In both articles “A Load of hot air” written by Cox & Vadon and “Grim Climate Predictions Not Exaggerated, Analysis Says” written by Roach are concerning about the effect of climate change in the near future. Although Cox, Vadon and Roach are agree that the cause of climate change is the release of greenhouse gases into the atmosphere, caused by human activities. The effects of climate change will have threaten water supplies bring more severe weather; threaten the live hood of nations situated near sea level. However, Cox and Vadon claimed that the effects of climate change were exaggerated by the media and the governments with a purpose to grab people attention on the issue. In the contrast, in Roach stated that the IPCC were underestimated and report the incomplete the cause and effect of climate change. He went on the explained IPCC has fail included the melting glacier in the poles and its effect on sea level due to climate change. Despite the debate for climate change, researchers agree that the threat climate change is real and human must act quickly to minimize its damage.
The main ideas of the articles above were stated clearly and well organized. However, in my opinion, the authors of the article “A load of hot air?” failed to convince the reader that the media and the government has exaggerated the effect of global warming. Based on recently researches conducted by National Aeronautics and Space Administration (NASA), climate changes will have a great impact on biodiversity. According to NASA, many species will migrate into areas dominated by farming, and this will form a barrier that prevents the movement of key species in response to climate changes; therefore it will jeopardize biological diversity (National Aeronautics and Space Administration, 2007). On the other hand, John Roach’s article was found to be more persuasive. Although, Roach focused his study on comparing the recent effects of climate changes to the IPCC report in 2001 he also able to protecting his opinion through researches of numerous universities. In addition, he wrote an article predicted that a continued increase in temperature will contribute to the extinction of nearly one-fifth of the world’s species by 2050 (John Roach, 2004). His prediction about species extinction is very similar to results from study of frog extinction conducted by Dr. Alan Pound.

Thank you for using the Jiskha Homework Help Forum. I think I see why no one has answered your post yet. First of all, you mentioned one paragraph. There are three dististinct paragraph and to punctuate that either skip lines between each paragraph or indent each one 5 spaces. My first inclination is to believe you are a second-language speaker because of the incorrect use of tenses, subject and verb agreement, using an adverb as an adjective, improper punctuation, etc. Hopefully, you can follow where my notes apply.

#1 Properly punctuating paragraphs
#2 What is the EXACT title of what you read? This needs proper punctuation as well to identify it.
#3 Jonh Roach basews what? There is no direct object, making this a complete sentence.
#4 "in the study of science" = why is it capitalized? This is the end of the sentence and requires either a period or a semicolon.
#5 green house gas = greenhouse is either one word (as you used it below) or you could hyphenate it: green-house gas
#6 The Science = is this the totle of a book? a body of analysists? Why is it capitalized?
#7 underestimated a few or it is not a complete sentence. Is this a positive or negative comment?
#8 and societal ones/changes as well = add this at the end to make it clearer
#9 IPCC would sound better as "THE IPCC"
#10 sea-level when used as an adjective modifying the noun
#11 again the capitalization is not consistent; "A Load of hot air" and "Grin Climate."
#12 are concerning or are about but NOT "are concerning about"
#13 Roach agree or are agreed, NOT "Vadon and Roach are agree"
#14 will have threatened or will threaten. dwelete the semicolon to add "and will threaten."
#15 with the purpose, NOT "a purpose to grab"
#16 people's attention
#17 In the contract Roach stated (the "in" needs to be removed
#18 The IPCC underestimaated (delete "were") and incompletely reported the cause. At any rate rework that sentence.
#19 went on and (not "the") explained that the IPCC has failed to include
#20 threat to or threat of + humans (plural) or humanity
#21 and were well organized to make it a bit clearer
#22 a compound subject/plural rquires a plural verb = the media and the government have (not "has")
#23 not the adverb but the adjective, or recently becomes recent
#24 recent researches by the NASA,(which you spelled out) rather than just plain NASA.

Hopefully I found everything, but feel free to rewrite, making all the corrections, and repost if you have time for final proofreading.

I have checked the grammar in the paragraph and made some corrections. Here is the corrected version:

Can someone read the paragraph below and check if my grammar is correct?

In the article "Grim Climate Predictions Not Exaggerated, Analysis Says," John Roach bases his report on the study conducted by The Science. According to Roach, in recent years, the concentration of greenhouse gases has been similar to the projections made in the 2001 IPCC report. Additionally, The Science claims that the IPCC may have underestimated a few climate threats in 2001. The IPCC report states that the emission of protective greenhouse gases, which make the earth habitable, is changing, resulting in current climate changes and potentially affecting the environment and society. However, Rahmstorf argues that the IPCC report is incomplete and fails to include the instability of the ice sheet in the Arctic, which affects sea level. Steffen claims that rising global temperatures greatly contribute to the rising sea levels through the melting of glaciers. Moreover, based on the newest ice observations, he stated that the IPCC's sea level predictions are too conservative.

Both articles, "A Load of Hot Air" written by Cox & Vadon and "Grim Climate Predictions Not Exaggerated, Analysis Says" written by Roach, are concerned about the effects of climate change in the near future. Although Cox, Vadon, and Roach agree that the cause of climate change is the release of greenhouse gases into the atmosphere caused by human activities, they have different opinions regarding the extent of the effects. The effects of climate change threaten water supplies, bring more severe weather, and pose a threat to nations situated near sea level. However, Cox and Vadon claim that the effects of climate change have been exaggerated by the media and governments in order to grab people's attention. In contrast, Roach states that the IPCC underestimated and incompletely reported the cause and effect of climate change. He further explains that the IPCC failed to include the melting of glaciers in the poles and its effect on sea level due to climate change. Despite the debate on climate change, researchers agree that the threat of climate change is real and humans must act quickly to minimize its damage.

However, in my opinion, the authors of the article "A Load of Hot Air?" failed to convince the reader that the media and the government have exaggerated the effects of global warming.

NASA states that many species will migrate into areas dominated by farming, which will create barriers that prevent the movement of key species in response to climate change, thus jeopardizing biological diversity (National Aeronautics and Space Administration, 2007).
