What miracles are needed to keep climate change within acceptable limits – 1,5 degree by 2100 – to keep?
Quite given scientists have the hope, not yet, but the report that the UN-klimaatpanel (IPCC) today published, makes clear, though, that there are actually miracles are necessary to achieve the objectives …
Quite given scientists have the hope, not yet, but the report that the UN-klimaatpanel (IPCC) today published, makes clear, though, that there are actually miracles are necessary to meet the objectives of Paris – the global warming should be limited to 1.5 degrees in 2100 – get. What are the main recommendations?
1. Find the spirit of Paris
The IPCC says is not what the politicians should do. The report is primarily a summary of the scientific state of affairs with a lot of numbers and graphs. Nevertheless, they formulate a ‘summary for policymakers’. It basically says in big letters “Do something now, idiots,” says Kaisa Kosonen of Greenpeace.
The report reads indeed like a cry for help to world leaders. In fact, get the urgent message that she is the ‘spirit’ of the UN climate conference of Paris should be found. Barely three years ago, it happened something wondelijks: the leaders of the main countries got over their own shadow and went there voluntarily agree that their efforts had to be stepped up. But three years later, reign in some key countries, other leaders.
The Us president, Donald Trump, kept his electoral promise and stepped out of the agreement. Officially, no other country followed him, but indirectly by the decision or influence. The sense of urgency is almost anywhere way. Australia has just launched its green plan, de facto, thrown in the rubbish bin. Brazil is at the point to do that. As Jair Bolsonaro is chosen, the trip from paris as well as certainly a fact.
And also the EU are dragging ever more with the feet. The German chancellor, Angela Merkel, is increasingly on the brake. Poland pulls without hesitation all the way up the map of the coal. And green prophets such as Emmanuel Macron and Justin Trudeau confess more with their mouth than with their policy the objectives of Paris.
Only Beijing remains plenty of his promises to keep, but also in China, energy demand continues to increase, so there is still always large-scale coal is burned.
2. Verzevenvoudig investments in renewable energy
The figures in the UN report dazzle. The warming to a 1.5 degree limit, there must be from now and up to 2035 annual 2.400 billion dollars to be invested in renewable energy. Bloomberg NEF, dealing with energy studies, berkende that there are currently approximately 333 billion invested. So, that means that the investments from tomorrow verzevenvoudigen. That will not happen.
At this time, coal is still responsible for 37 percent of the total, gas for 24 percent. Nevertheless, it would, by 2030, 45 percent of the energy is renewable. Coal would then be almost completely phased out. Meanwhile, increasing the greenhouse gas emissions from power plants again.
One bright spot: according to a new report from the International energy agency, the proportion of green energy in electricity production to 25 percent in 2017 to 30 percent in 2023.
3. Plant a forest the size of Australia
We can on a large scale forests for a tree, because trees extract CO2 from the air and store it. Currently, global forest about a quarter of the CO2 that human emissions, from the air.
But all salvation is not of the trees. Like the forest, is a fundamental difference, then there is a forest the size of Australia to be planted. These forests would then be likely to take the place of land used for food production. Also that is not self-evident. By 2050, a growing world population, about 2 billion people. Who should eat.
4. Remove the CO2 from the air
Not only do plants absorb CO2. There is also technology that does the same thing. Through a chemical process the CO2 released by the burning of fossil fuels is captured and stored. the Norwegian government, for example, believes very much in this technology. The country is even prepared all the carbon dioxide that Europe releases on the catch.
In its report, the IPCC a lot of attention to the system. But here, too, can ask questions on the feasibility, at least in the short term. It remains to be a energy hungry, and expensive process. “It is not yet proven on a large scale workable’, it sounds in the report.
Economic is the process only profitable if the price of CO2 significantly increases. On the European emissiemarkt takes a ton of CO2 is now approximately 20 euro. That price must be raised to at least 60 euros.
