I’ve never considered myself an alarmist, but a lot of the recent data on the severity and acceleration of climate change is terrifying to me. Where to even start - mass insect extinction predicted by 2100, arctic sea ice depleting with an ice-free summer predicted over the next few years, mass decline of fish stocks, coral and aquatic life, unprecedented heatwaves and forest fires around the world, and absolutely no end in sight.
It’s looking like we are going to surpass the IPCC’s 1.5 degree limit within a couple of decades at most. This increase is felt much more in the arctic region, which plays an incredibly important role in modulating the climate of most of the planet. No sea ice leads to increased heat absorption of the northern oceans, which could lead to mass amounts of methane released from the slush it currently resides in at the bottom of the ocean. Due to the power of methane as a greenhouse has and its resiliency in the atmosphere, this would be very, very bad.
I think a lot of people picture climate change as a few more storms, a bit warmer summers, and trouble for a few South Pacific islands, and the media likes to use the year 2100 in their most dire forecasts (you’ll be deceased, your kids will be either deceased or very elderly, business as usual), but there is a growing body of evidence that shit could really hit the fan in the next couple decades, potentially even years.
Guy McPherson is the most vocal and one of the most extreme in his views. He thinks humanity will be extinct by 2026. He gets criticized a lot because he incorrectly forecast “peak oil” a few years ago, but a lot of the science he draws from is hard to argue. Him aside, more and more climate scientists are entering the “we’re fucked” mindset, that climate change is already baked in and that we’re looking at a future that is too horrific to picture. Even Canadian climate scientist David Suzuki, who has been a call-to-arms optimist about climate change over the past 30 years, has in recent interviews been very pessimistic and even seemed full-blown depressed about the current path we are on.
What are everyone’s thoughts on this?
