In his latest newsletter from Poland, David Oldroyd discusses the Drawdown Review, which details how we might limit global warming. There are two Drawdown scenarios. They align, respectively, with meeting a minimum goal of 2°C and a more ambitious goal of 1.5°C. Drawdown Scenario 1 is roughly in-line with 2 ̊C temperature rise by 2100, while Drawdown Scenario 2 is roughly in-line with 1.5 ̊C temperature rise at century’s end.
To do this, the world needs to reduce, and ultimately replace, fossil fuels with non-carbon energy. Then, we need to protect and expand the planet’s natural carbon sinks. This includes all our tropical forests which have been facing increased deforestation, and includes soils. Building onshore wind turbines, reducing food waste, and eating plant-rich diets are among the top 10 actions the world needs to reduce greenhouse gas emissions.
The report has considerable and rich detail on how this might be achieved. Education has a significant role to play.
David comments: “But none of these or the 66 other solutions alone is enough to successfully solve the climate crisis. Their ability to work depends on every single other solution happening. Project Drawdown estimates using these 76 solutions alone, we can reach a moment when atmospheric carbon dioxide peaks as early as 2040. Aggressively pursuing these solutions would cost between $23.4 to $26.2 trillion but would result in $96.4 to $143.5 trn. saved.”
