The world is facing a critical time in human history, and climate change is at the forefront of this existential crisis. The latest research warns that the harm caused by global warming would be fast to arrive and slow to disappear, even after temperatures fall again. Just a few years of global temperatures above 2°C could transform the world's most important ecosystems. It is essential to take immediate and drastic measures to limit global warming to 1.5°C. Delaying cuts to emissions means that the world overshooting 2°C is a best-case scenario. Negative emissions technologies to lower greenhouse gases in the atmosphere over several decades are too risky to contemplate. The world needs to recognize the urgent need for global cooperation to tackle climate change before it's too late.

Furthermore, research has shown that crops like wheat and rice produce lower levels of essential nutrients when exposed to higher levels of carbon dioxide. Plants grew bigger but had lower concentrations of minerals like iron and zinc, which could lead to protein deficiencies in the population. Climate change can disrupt most of the biophysical conditions to which humans have adapted over millions of years, impacting our health and well-being. The emergence of the field of planetary health aims to emphasize the importance of taking care of the planet's health to safeguard human health. It is our collective responsibility to work towards preserving our planet and safeguarding our future.
