Scientists agree that limiting global warming to 2°C over pre-industrial levels won't keep us from averting climate disaster. A sustainable solution that avoids severe damage to the planet requires more aggressive action. An alternative 1.5°C target might ensure that species would be able to keep up with a changing climate; almost half of the coral reefs would remain on the planet; sea level rise would remain below 3.3 feet, ocean acidification impacts would stay at moderate levels.
Is a 1.5°C alternative technologically feasible? Yes. But strategies need to involve immediate action and an additional scaling-up of clean energy technologies.
Often, the impacts of our changing climate seem far away, and not relevant to our daily lives. But it is relevant and already affecting us and causing suffering for millions of people as they struggle to meet basic needs amidst heat, drought, floods, and resulting wars.
