Whoever the UN Environment Chief is, he has completely missed the point. And I am only beginning to understand the horrific nature of this problem myself. The real problem (he may have heard of it) is the ‘runaway greenhouse effect’; where positive feedback systems will keep pushing temperatures up. There is no upper limit because we now have so much methane frozen at the bottom of the sea. In combination with the vastly accelerated release of carbon dioxide and methane from fossil hydrocarbon extraction and consumption, we are now, unwittingly, literally staring into the abyss. There is no way of stopping a runaway greenhouse effect once it gets started.

The worlds most consistantly accurate climate scientist, James Hansen, whose predictions have been correct since 1980; provides a lot of detail in his 2009 book (which is already frightening accurate).

We are now entering a time of increased certainty about the causes and effects of large emissions releases in Earths history. The problem we face is that methane clathrates lying frozen within the ocean will start to thaw as ocean temperatures increase, leading to a new reality. The methane will drive further temperature increase, which will drive further thawing and thus further temperature rise. During the PETM 65m years ago, temperatures rose by 12-14°C. However, there is now almost double the methane clathrates, and the process is happening at a vastly accelerated rate, meaning that negative feedbacks are very unlikely to ever stabilise the temperature once it reaches a 20°C equilibrium. What are now carbon sinks (soil, vegetation and sea) will start to release rather than absorb carbon dioxide. There is no upper limit to this temperature increase.

This process will be initiated once we reach 2-3°C.

It is time to wake up: climate change does not mean it will get a bit hot. It means that within a few centuries, all life on earth is going to die, permanently.

It is not humans who will cause the tragedy of the end of life on earth – it is the positive feedback systems that we will put in train.

With regard to the answers to this problem; we really do need to understand that we cannot electrify everything as it simply won’t work. We cant store that much electricity. So we need to replace liquid & gaseous fossil fuels with hydrogen; almost everywhere. I hope people see through the reams of lobbiest misinformation and fully understand this fact, because there is no other way to decarbonise all these sectors, and industry, using renewable energy. It really, really is time to wake up.
