    1124. The Recent Surge in Atmospheric Methane Driven by Increased Emissions from Microbes

    The increase in the atmospheric methane recorded an all-time increase from 2020 to 2022. The paper, published in PNAS, estimates that the recent surge in atmospheric methane was primarily caused by increased emissions from wetlands, waste, and microbial sources from agriculture.

    1123. Increase in Greenhouse Gas Emissions from Forest Fires Related to Climate Change

    Anthropogenic climate change has made forest fires bigger, more intense, and more common, but analyzing their causes is often difficult. Using a machine learning approach, the paper published in the journal Science analyzes differences in sensitivity to climate, anthropogenic factors, and vegetation across global forest pyromes and finds that climate change has significantly increased emissions of forest fires in the extratropics.

    1122. The Hydrological Cycle as a Global Common Good

    The world is facing an increasing frequency of water-related disasters such as floods and droughts, and it can be said that this is the first time in human history that such an imbalance in the water cycle has occurred. In order to achieve a fair and sustainable future for all, it is imperative to restore the stability of the water cycle. The Global Commission on the Economics of Water emphasized the importance of recognizing the hydrological cycle as a global common.

    1120. Overconfidence in Climate Overshoot

    Global efforts to reduce greenhouse emissions remain insufficient to meet the temperature targets of the Paris Agreement. For this reason, discussions are being held on the assumption of so-called overshoot pathways, which temporarily exceed the target global warming limit before returning the temperature to safer levels. A paper published in the journal Nature said there is no guarantee that temperature decline will be achieved after an overshoot, and called for short-term, rapid emissions reductions to reduce climate risks.

    1119. International Day for the Eradication of Poverty

    The International Day for the Eradication of Poverty is an international day established by the United Nations. As the 2024 Nobel Prize in Economics was awarded to a researcher who pointed out the importance of political institutions that determine the difference between prosperous and  poor countries, it is urgent to act together for a just, peaceful, and inclusive society to end social and institutional abuses.

    1115. Global Drought Overview

    According to a report published by the European Union at the end of September, a severe drought is currently affecting large areas of the world. The combination of the strong positive state of the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole, as well as climate change, is negatively impacting agricultural productivity across a wide range of regions and raising concerns about an urgent food security crisis. In the face of climate change, crop genetic resource diversity is essential for maintaining the resilience of agriculture. On October 11, we will host a special symposium for Dr. Cary Fowler, winner of the 2024 World Food Prize, for his significant contributions to the conservation of crop genetic resource diversity.

    1114. Methane Surges in 2020-2022 Were Driven by Inundation of the Wet Tropics

    The increase in methane gas in the atmosphere has accelerated over the past decade, with the highest increase on record from 2020 to 2022. A paper published in the journal PNAS showed that inundation of the wet tropics caused a methane surge in 2020-2022.

    According to the World Bank's blog, domestic food price inflation remains high in many low- and middle-income countries. Factors affecting global food security include the impact of record-breaking high temperatures on commodity crop markets and the surge in trade-related restrictions following Russia's invasion of Ukraine.

    1112. Global Food Price Trends for September 2024 

    The Food and Agriculture Organization of the United Nations (FAO) released its global food price trends on October 4. The value in September 2024 averaged 124.4 points, up 3% from August and the highest monthly price indicator increase since March 2022. Prices for all commodities included in the price indicator increased, ranging from 0.4% in meat prices to 10.4% in sugar prices. This figure was 2.1% higher than last year, but 22.4% lower than the all-time high in March 2022.
