It’s almost too much to get your head around: that we have shaped the world so profoundly in what is, in the Earth’s history, the blink of an eye. Most of the geological epochs in the past 4.6bn years have lasted millions of years each time. According to the Anthropocene Working Group, the Anthropocene is thought to have begun in the 1950s, when industrialisation accelerated. One of its hallmarks is that we humans are affecting the conditions of life everywhere, all at once. We have instigated a sixth mass extinction of other species; we have changed the biosphere and altered the chemistry of the oceans by burning fossil fuels; we have uprooted forests and poisoned land with chemicals.
I've been posting about this topic for several days now. It's because I personally feel vulnerable to disasters brought about by extreme effects of climate change, e.g., unusually severe weather, flooding, and unusually hot days (and the excess load on the grid this brings about). These are what I prep for.
