Climate change poses a risk to global food security. Weather and climate extremes, such as prolonged drought, heavy rainfall and heatwaves, can lead to harvest failures. These are occurring with increased magnitude and frequency on a warming planet. In addition, such events can disrupt supply chains, decreasing food supply and leading to price spikes.

Now that the Earth has warmed roughly 1.2°C, “once-in-a-century” heatwaves, forest fires, and floods are becoming more familiar to us. But there is still a massive difference between 1.2°C and 1.5°C, and the science shows that it is still possible to end this century at or below that threshold.

The IPCC's final report of its Sixth Assessment Cycle is a comprehensive overview of the state of climate change and a roadmap for action in this critical. Our experts pull out the key messages.

The Paris Agreement aims at “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels, recognising that this would significantly reduce the risks and impacts of climate change”. Here we address some commonly asked questions.

This piece, originally published in The Conversation, highlights our research into decarbonisation scenarios put out by the IEA, BP, Shell and Equinor. Our research team found that none of the assessed scenarios from oil majors are consistent with the Paris Agreement.

The 1.5°C limit in the Paris Agreement is now widely accepted as the goal towards which climate policy is working. The science behind the goal is extensive and the Agreement’s language is precise. We explain how it should be interpreted.
