Climate Change Threatens the World’s Food Supply, United Nations Warns

The world’s land and water resources are being exploited at “unprecedented rates,” a new United Nations report warns, which combined with climate change is putting dire pressure on the ability of humanity to feed itself.
The report, prepared by more than 100 experts from 52 countries and released in summary form in Geneva on Thursday, found that the window to address the threat is closing rapidly. A half-billion people already live in places turning into desert, and soil is being lost between 10 and 100 times faster than it is forming, according to the report.
Climate change will make those threats even worse, as floods, drought, storms and other types of extreme weather threaten to disrupt, and over time shrink, the global food supply. Already, more than 10 percent of the world’s population remains undernourished, and some authors of the report warned in interviews that food shortages could lead to an increase in cross-border migration.
A particular danger is that food crises could develop on several continents at once, said Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies and one of the lead authors of the report. “The potential risk of multi-breadbasket failure is increasing,” she said. “All of these things are happening at the same time.”

What Satellite Imagery Tells Us About the Amazon Rain Forest Fires - The New York Times

Scientists studying satellite image data from the fires in the Amazon rain forest said that most of the fires are burning on agricultural land where the forest had already been cleared.

Most of the fires were likely set by farmers preparing the land for next year’s planting, a common agricultural practice, said the scientists from the University of Maryland. Satellite images like the one below show smoke plumes from fires emanating from agricultural areas.
The majority of the agricultural land currently in use in Brazil’s Amazon region was created through years of deforestation.
“Most of this is land use that have replaced rain forest,” said Matthew Hansen, who is a co-leader of the Global Land Analysis and Discovery laboratory at the University of Maryland.
“Brazil has turned certain states like Mato Grosso into Iowa,” said Mr. Hanson, referring to the Brazilian state on the southern edge of the Amazon region. “You’ve got rain forest, and then there’s just an ocean of soybean.”
The grid of maps below show the month-by-month pattern of fires across the Amazon rain forest in Brazil each year since 2001. The increase in fires every August to October coincides with the season when farmers begin planting soybean and corn.

How climate change threatens public health » Yale Climate Connections

From prolonged droughts to dangerous sun exposures, the weather affects human health in numerous ways, and climate change has already ratcheted environmental health threats up a notch. Disease-carrying bugs have expanded their range, hotter heat waves last longer, and storms have gotten more extreme.

“Climate change is impacting our communities, in our backyards, right now,” says Amir Sapkota, a professor at the Maryland Institute for Applied Environmental Health.

Citing health threats posed by climate change, more than 70 major medical groups in the U.S. released a call to action in June 2019 declaring climate change “a true public health emergency.”

Jonathan Patz, M.D., MPH, director of the Global Health Institute at the University of Wisconsin, is an expert on climate change and public health. His view: “It’s so important that people recognize that climate change is about our health. There are so many pathways through which climate impacts our health.”

Those pathways include heat, air pollution, extreme weather, vector-borne diseases, and access to safe water and food. The health risks posed by climate change already disproportionately harm marginalized groups including people with disabilities or infirmities, low-income families and individuals – and climate change is likely to deepen those disparities.

Iceland holds ceremony for first glacier lost to climate change | News | DW | 18.08.2019

Iceland has been commemorating the loss of Okjokull with the prime minister and guests from international universities and the United Nations. A ceremony at the site highlighted the urgency of climate protection.

Iceland has been commemorating the country's first glacier lost to climate change, with a memorial plaque warning of the effects of global warming being installed at the site.

Icelandic officials, activists and others took part in a ceremony on Sunday that included poetry, silence and political speeches on the urgency of taking action to curb rising global temperatures.

The disappearance of Okjokull, a glacier in the west of the sub-Arctic island, is being seen as directly due to the warming of the climate caused by human activity.

The memorial for the Icelandic glacier is the first of its kind. The words are written by Icelandic author and poet Andri Snaer Magnason.
