The scientific truth is that man is affecting the climate faster than what the climate would change naturally. You might say this is debatable, and it has been debated, thousands of times as a matter of fact, and the scientific consensus still remains the same: Humans are affecting the climate at a rate that is unsustainable to life as we know it.
Dead right. I really don't know why there would be any continuing debate on this subject, certainly for anyone with a physics-based education who has studied even a small portion of the reams of data and lectures available from credible sources. For someone without a suitable education, they would be well-advised to accept expert opinion rather than think they know better. Every scientist in the world would love to be the one person to solve this nasty problem and become the most famous person in history, yet no one has stepped up with an answer or uncovered any mass conspiracy, certainly not any of the politically-motivated or industry-funded deniers.
The difficulties the general population have with understanding this is clearly because humans are not hard-wired to understand threats which are not immediately obvious. Adding to that the fact that warming is due to long-term cumulative emissions and delayed decades by the thermal masses involved. The US for example is roughly responsible for 27% of the total cumulative warming but today contributes only about 11% annually.
Our next few generations are absolutely in dire trouble. The time to act was 1980. Today, we are almost locked in to 1.5°C (2040-ish) and will easily exceed 2, probably more because of the enormity of accepting that we must stop burning all fossil fuels immediately. Today we see the climates effects of 1°C and it it unknown how worse that can get with 1.5 or 2 but anyone can guess it won't magically improve.
Once the Arctic summer ice mass reaches zero (<2040) the latent heat storage component disappears and the northern hemisphere weather could radically change. Consequently, as countries experience summer wet bulb temperatures over 35°C there will be mass deaths and mass migrations, and guess what country is a good place to go?
