Yes, I started learning drawing as an adult with zero natural talent. For me, it wasn't about becoming exceptionally good but about exploring and finding pleasure in the process. I took drawing classes following the "Drawing on the Right Side of the Brain" method, which I highly recommend.
Even if we are close to peaking emissions, we must consider the phenomenon of accumulation. Given that CO2 has an effective lifespan of around 100 years and methane about 10 years in the atmosphere, reductions in emissions now will still result in these gases accumulating and impacting the climate for decades to come.
