On Friday March 15, 2019 children all over the world walked away from school and joined organized marches to raise their voices in favor of combatting global warming.
In Africa, Isaac Oindo, from NGO Power Shift Africa, said: “Some people think climate change is only a future problem but here in Africa we know that it is happening now. We're living through it. However we know that it is going to affect the next generation even more severely which is why it's no surprise to see school children here in Africa and around the world going on strike to demand action.”
In Berlin, Luis Anzolin, age 15, declared “We’re here because it’s important, it’s about our future. Because let’s face it, those sitting in Parliament will probably not be there in the future and it’s going to affect us.”
The black line in the lower left represent actual historical data, with each decadal year given by a dot, some of which show the year. It’s seen that this historical “hindcast” reproduces the historical data very well, giving credence that the modeling is correct. The four successive emissions scenarios follow almost a straight line toward the upper right, toward higher CO2 levels and higher projected temperatures.
It’s already turning out that our children are right to be alarmed and frightened about their climate future. In the five years since 5AR was issued, accumulated CO2 in the atmosphere has continued to increase year by year, as has the long-term global average temperature. The world has been afflicted with ever more severe bouts of extreme weather and extreme climate, just as the climate scientists writing 5AR foresaw. These include, in differing regions of the planet, drought and reduced agricultural yield, heat waves and long-term hot temperatures also reducing agricultural yield, more extreme precipitation resulting in fresh water floods, more severe storms, fair weather tidal flooding along shorelines, and ocean warming resulting in displaced fisheries. The science of attribution has made great progress in recent years; events such as listed here in many cases are deemed to have been made more severe because of global warming. Our perceived sense of worsening weather and climate events is real, and is due to worsening warming.
