From what I know following this problem, the agreement of the scientific community about the increased global warming in the next decades, within the year 2050, is nearly total.

They agree on the fact that the climatic change has started at least 15 or 20 years ago, that it regards the whole planet, from the pole to the equator and mainly on the CAUSES of the greenhouse effect at the origin of the global warming, created by the massive combustion products of our industrial civilization, mainly produced by the burning of fossil fuels (CO2 and CH4).

The impact of our still barbaric and polluting industrial development is clear and its consequences are recent, regarding the last 100 years, with an acceleration in the last 20 years.

They underscore the increased intensity of atmospheric phenomena, like heavy rains of tropical type, typhoons and tornadoes, floods and, at the opposite, longer dry periods.
Rains will not increase and in many regions they will decrease, (already occurring) but they will become more irregular and violent, concentrated in short periods; rains similar to the tropical type, also in the full of temperate regions, like central Europe, North America and Asia.

They agree on the climatic consequences of this trend, but less on the speed of this change and the average temperature (T)increase; some, more optimist, predict an increase of "only" 2-3C within 2050, while the pessimist predict 5-6C.
Only 2 C more would be already a real mess, in such a short period, if compared with the slowness of the natural climatic changes that we have already discovered for the last thousands years.

Also the melting of ice caps, causing the increase of sea levels finds the agreement of scientists, but its amount is still uncertain, depending from the real increase of the average T in the world.
3 metres, 5, 10 metres or more?
Only 3 metres would be enough to submerge wide flat coastal areas in all the world, very often densely inhabited and cultivated.
All the geographic maps would be drawn again in few decades and not for little local details.

The uncertainty is on the exact NUMBERS of this global warming, not on its occurrence and on the irreversibility of this process today.

This agreement of the scientific community is still not enough to convince the politic leaders of our world, especially if they belong to Right parties or to developing Countries, willing of not arresting their wild, partial and polluting economic development.

Even more difficult is to convince or oblige the industrials and businessmen of all the world, "the capitalists", using a too much abused word.
To gain the highest profits in the short term, they would let all the rest of the world go to the hell, as if they lived on another planet.

Their resistance and the delay and disinformation they're producing against the interventions proposed to stop this process could be fatal to the whole mankind and, maybe, to most of the life on the Earth.
Scientists and technicians have their defects but, also when they all agree on a serious problem like this, they don't rule the world, this is clear.
