If all the Paris accords were implemented:
1. When would we see an effect on the climate?
2. When would it stop warming? How many degrees?
3. How much would the world have to pay per year to complete the Paris accords?
4. Would the sea level stop rising? When?
Please, no links. No one wants to read through long reports. Just provide the answers simply.
The simple answer (to the meaning of life, the universe, and everything) is:
42.

The more elaborate short answer, simple enough for even folks like Trump to understand (I hope, although there's a difference between understanding and acting in accordance with that 'knowledge'):
1. The moment we change, the effect will change. It may take a while to be measurable because these are slowdowns in an acceleration at first, and it depends on how much of a change is introduced into the system and how fast.
2. It will reduce warming immediately, hopefully to a level that Mother Earth can find somewhat of an equilibrium again. Even with the Paris agreements, the warming will not stop, but the aim is:
"Holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change"Skeptics (realists?) say that that goal is optimistic, and will not be reached by the current actions taken (2.5-3 °C may be more likely).
Without action, it will keep
accelerating for quite a while.
3. The pledges and other associated costs are specified in the agreement to which you do not want a link.
However, make no mistake that not acting will cost more. And it will be harder and more costly when action is postponed.
4. When the temperature
drops (not slows down increasing, but going
down), the expansion of the water mass is reduced and thus the water volume is also reduced. It may take a while (50-100 years for the climate to reach a new equilibrium) for the atmospheric climate effects on water level to lead to a reduction.
Just to give you an idea of cost due to only waterlevel rise (we're not even calculating the much higher cost of droughts, food shortages, mass migration, war, etc.):
