In general, this news item wants to show us what Paris agreement consists of. It's a deal to tackle about the Global Climate Change and it is also a pledge for those countries who take part in. They want to step-up the Paris Agreement of cutting the emissions of greenhouse gasses to be introduced in the rest of the countries throughout the world, in other meanings, they want to encourage other countries to take part in, even also the countries who have already been affected by this took action in the earlier Paris Agreement Congregation because they wanted "action" not "symphaty".
Besides, those who couldn't participate in the Paris Agreement because of the lack of wealthy, they were told to wait and receive money from other countries to achieve newer technologies that support renewable energy, even though they didn't had the money to buy it. It's like a Global Unification with one goal: reduce the global temperature below 2.0, the one before the pre-industrial period. With this they want other countries to cooperate and endeavour to make this arrangement something real, a road that humanity will take on to achieve one of the hardest historical achievements.
In my opinion, I fully agree what they are doing, all those things they do... like, richer countries finance poorer countries to take part in the agreement and diminish the greenhouse gasses by buying better gas filters, better renewable energy machinery.... Indeed, this is a good thing for humanity to do, but the question is: Will have humanity the actual will to complete what they promise? Have they any wish in doing good in our planet? Such questions are woefully not known, every single person has different thoughts, some of them good.. some of them bad....
I want countries to really buy new renewable energies because this would make our air less polluted and I would feel happier and more cool, in my opinion they should reduce global wars too they make misunderstandings between countries and makes decisions hard to make with them, in other words, they get less cooperative if they feel opressed by other states.
In conclusion, this agreement, even if it takes long time to accomplish, it'll make a good step to humanity towards natural auto-renovation and to have respect to nature, not like nowadays that they cut forests endlessly without recycling papers (for exemple).
