On the one hand, there are people, I would like to think the majority, who believe that it is true, that the earth's climate is getting warmer and warmer, of people believe climate change and global warming are true and that we must take immediate actions to avoid future repercussions for the next generations. On the one hand, I would like to think the majority of people believe climate change and global warming are true and that we must take immediate actions to avoid future repercussions for the next generations.

I suggest looking up a guide on run-on sentences- using many dependent phrases that need commas (,) is tiring for the reader to process. While long sentences are not inherently bad, be careful how you use them. Semicolons (;) are used to separate independent clauses that can stand on their own as complete sentences.

And on the other hand, there are people who deny the existence of ithis climate process. And on the other hand, there are people who deny the existence of it.

I would not call it a climate 'process' since it isn't inevitable.

And oOn the other hand, there are people who deny the existence of this climate processat climate change is real. On the other hand, there are people who deny that climate change is real.

Starting sentences with "and" or "but" can be seen as informal. While technically grammatically correct in some cases, this is accepted more as colloquial English than in written English. "Climate process" is not a commonly used term to describe climate change. "The existence of this climate process" sounds clunky, and benefits from more concise wording.

And oOn the other hand, there are people who deny the existence of this climate processsituation. On the other hand, there are people who deny the existence of this situation.

"Climate process" sounds like, at least to me, a natural occurrence, like the water cycle.

This group is curiously enough made up of conspiracy theorist of the global warnings. This group is curiously enough made up of conspiracy theorists.

"of global warming" would be redundant, unless its something specific that they believe about global warming. For example, they could say that cars don't cause pollution, and if you included that then it wouldn't be redundant.

This group is curiously enough made up of conspiracy theorist of the global warningmade up of global warming conspiracy theorists. This group is made up of global warming conspiracy theorists.

"Curiously" would imply that the following information "enough made up of conspiracy theorist of the global warning." would be strange or unexpected. However, climate change deniers being conspiracy theorists isn't surprising. Also, you made a typo on "warming".

This group is, curiously enough, made up of global warming conspiracy theorist of the global warnings. This group is, curiously enough, made up of global warming conspiracy theorists.

Anyway, as far I am concerned, climate change is a real problem that we don't take as seriously asfor what it really is. As far I am concerned, climate change is a real problem that we don't take as seriously for what it really is.

I would pick either "Anyways" or "As far as I am concerned" (you are missing "are" in the second phrase). Just one transition is enough for the reader to know you're going into a different sentence. I think "as far as I am concerned" is stronger since it stresses your opinion. I also switched "as it really is" to "for what it really is" since the "for" would imply a stronger relationship between the nature of climate change and how we don't take it seriously. "As" in this case would just be for describing a condition.

We are not conscious of the danger it represents to the planet and w. When we finally realize ithat, it may be too late. We are not conscious of the danger it represents to the planet. When we finally realize that, it may be too late.

Again, this is a bit lengthy.

However, taking actions is not that easy. However, taking action is not that easy.

However, taking actions against climate change is not that easy. However, taking action against climate change is not that easy.

I would suggest switching between pronouns and the noun itself for smoothness. (ex "it" the pronoun and "climate change", the actual noun)

However, taking actions is not that easy. However, taking action is not that easy.

The reason I am saying this is that, in my opinion, this issue sets out some difficult problems: First, how will the change in the productive and economic system carry out? The reason I am saying this is that, in my opinion, this issue sets out some difficult problems: First, how will the change in the productive and economic system carry out?

The reason I am saying this is that, in my opinion, this issue set oubrings with it some difficult problems:. First off, how will the changes in the productivesupply chain and economicy system be carryied out? The reason I am saying this is that, in my opinion, this issue brings with it some difficult problems. First off, how will the changes in the supply chain and economy system be carried out?

The reason I am saying this is that, in my opinion, this issue set outat we don't take climate change seriously enough is because it illustrates some difficult problems:. Firstly, how will the change in the productive and economic system carry out? The reason I am saying that we don't take climate change seriously enough is because it illustrates some difficult problems. Firstly, how will the change in the productive and economic system carry out?

The issue with having two transitions comes up again here. Having both "The reasoning I am staying this is that" and "in my opinion" is too much. Emphasizing the reason you are talking about this issue seems to be the strongest option since you go into multiple reasons why this issue matters.

AndSecondly, who will bear the cost? Secondly, who will bear the cost?

This is another instance of using a coordinating conjunction (ex. and, but, or) to start a sentence. To match the structure of the previous transition, I would suggest "secondly".

And mMost importantly, up to what poiextent will different countries be involved in combatting climate change? Most importantly, to what extent will different countries be involved in combatting climate change?
