Air temperatures above the earth have risen 1.5 degrees Celsius since the pre-industrial era, twice as high as the global average that also includes the oceans.
To combat this trend, the Intergovernmental Panel on Climate Change (IPCC), in a study presented Thursday in Geneva, points out that you have to eat less meat. Leading politicians are expected to consider the findings of the IPCC at the next UN Climate Action Summit on September 23 in New York.
Agriculture, forestry and other human uses of the land they currently represent 23% of greenhouse gas emissions produced by humans. The IPCC advocates a global shift towards the consumption of more plant-based foods and less meat and points out that this would reduce greenhouse gas emissions from livestock and free up land for more sustainable uses.
"We don't want to tell people what to eat," he says Hans-Otto Pörtner, an environmentalist who co-chairs the IPCC working group on impacts, adaptation and vulnerability. "But in fact it would be beneficial, both for the climate and for human health, if people in many rich countries consume less meat, and if the policy creates appropriate incentives for that effect."
Indigenous communities and groups should also be involved in better sustainable management of their lands, including methods to use organic matter to increase soil carbon content, according to IPCC researchers.
On August 8, the IPCC published a summary of the report, which is designed to inform the upcoming climate negotiations amid the worsening of the global climate crisis. More than 100 experts compiled the report in recent months, about half of which come from developing countries.
The panel also called for efforts to curb the loss and waste of edible foods, which are estimated to represent at least 8 percent of the greenhouse gases produced by humans.
