The conclusions of the sixth Assessment Report of the UN Intergovernmental Panel on Climate Change (IPCC) revealed that the effects of global warming will lead to an increase of 1.5ºC in the planet's temperature and, with this, food production around the world will suffer.

According to 'The Guardian', citing several scientists, these effects will have a direct impact on food supplies over the next two decades.

The IPCC reveals that rising temperatures will mean that there will be more times of the year when temperatures exceed what crops can withstand.

These changes will also impact changing rainfall patterns, which "will leave many areas vulnerable to drought, while extreme weather conditions will make farming more difficult and damage crops."

Ilan Kelman, a professor specializing in disasters and health at University College London, said, "Increased heat and humidity will harm crops and livestock, with droughts and floods having the potential to destroy crops. Major changes in agriculture and livestock will be needed to combat these effects."

Currently, more than 80% of the calories consumed worldwide come from just 10 agricultural plants, such as rice, corn, and wheat.

British Prime Minister Boris Johnson has released a video outlining four areas of focus to combat climate change, these being: banning coal as a source of power generation by 2040; doing the same for fossil fuels for transport; getting countries to pool money to help poorer nations with climate change; and ending "the slaughter of forests."

US President Joe Biden said, according to 'The Guardian' that "the signs [of global warming] are unmistakable. The science is undeniable. And the cost of inaction continues to rise."

Australian Prime Minister Scott Morrison pointed the finger at China, saying that it is responsible for "two-thirds of global emissions," and that its emissions "accounted for more than the entire OECD combined."

For its part, the Chinese government issued a statement to AFP, according to the same source, saying that "China has insisted on prioritizing sustainable, green, low-carbon development," and that the goal is to "strictly control" the growth of coal-fired factories.

The reality of the impact of climate change will not be fully revealed until next year, when the IPCC publishes the second part of its historical assessment, which will cover the impacts of climate degradation on key areas of human life and the planet.
