If humanity continues on its current path, we’re going to leave a hotter, deadlier world for the children of today and all future generations.

Earth desperately needs COP27 to succeed. I’m a climate scientist and I believe world leaders should have these three things top-of-mind heading into the conference.



1. Our planet is undeniably in crisis

So far, Earth has warmed just over 1℃ relative to pre-industrial levels, meaning we’ve already damaged the climate system. Our greenhouse gas emissions have already caused sea level to rise, sea ice to shrink and the ocean to become more acidic.

Human health is also on the line. Research last month revealed the climate crisis is undermining public health through, for instance, greater spread of infectious diseases, air pollution and food shortages.

Among its disturbing findings, heat-related deaths in babies under a year old, and adults over 65, increased by 68% in 2017-2021, compared to 2000-2004.

2. Emissions reduction is too slow

Some countries, particularly in Europe, are succeeding in reducing greenhouse gas emissions through transitioning to renewable energy.

But globally it’s not happening fast enough. A UN report this week found if nations deliver on their climate action goals for 2030, Earth will still heat by about 2.5℃ this century - overshooting the Paris Agreement goal to keep global warming well below 2℃.

3. The stalling must end

With so many challenges facing the world, including the Russian invasion of Ukraine and the cost of living crisis, it may be tempting to view climate change as a problem that can wait. This would be a terrible idea.

Climate change will get only worse. Every year of delay makes it much harder to prevent the most dangerous climate projections becoming a reality.
