Carbon in the sky and climate change: Earth Day by the numbers

Since Earth Day – the annual day for the environment – started being observed, global warming has dramatically worsened. Could carbon pricing be a silver bullet?

Looking back over the past five decades, there’s been a fairly steady descent into our current climate crisis as ballooning populations and hungry economies have relied heavily on burning fossil fuels for power. Thinking about climate change can be overwhelming. But for those of you who fear it’s too late to change the planet’s fortunes, take heart. Because some experts think humanity can still turn things around for Mother Earth. Some find cause for optimism in expanding energy efficiency, electrification or geoengineering. Others believe that carbon pricing is the number-one solution to bake the true cost of emissions into the economies and reorient them towards a more planet-friendly trajectory.
