Scientists associated with China's Institute of Oceanology have deployed a long-term ocean observation platform to study cold seeps in the South China Sea. What are cold seeps, you might ask? This useful pair of videos from the U.S. National Oceanic and Atmospheric Administration (NOAA) explains what a cold seep (also known as a methane seep) is, what a hydrothermal vent is, and how they are different: oceanexplorer.noaa.gov/facts/seeps-vents.html

NASA has released this map showing the world's major carbon dioxide emitters (in brown, with 3D shading) and absorbers (in green) from 2015-2020. Because this map is based on data collected by satellite, it includes measures for countries that have not reported emissions data in years. The major carbon-absorbing countries have large swaths of forest, particularly the taiga (or boreal forest) of Canada and Russia. news.yahoo.com/nasa-map-shows-which-countries-are-releasing-and-absorbing-co2-123341959.html

The biogeography of Siberia is changing as melting permafrost in the tundra is exposing viruses previously unknown to science, some of which have been trapped in the ice for tens of thousands of years. www.washingtonpost.com/climate-environment/2022/12/02/zombie-virus-russia-permafrost-thaw/

As this map shows, thus far, the winter has proved warmer than usual in most of Europe, which has allowed natural gas and other energy prices to fall back to more normal levels. But a colder-than-usual winter in parts of Asia is creating natural gas shortages and heating problems in China, in particular.   (Map from www.nytimes.com/2023/01/25/business/china-natural-gas-shortages.html.)

Megacities are generally defined as metropolitan areas of at least 10 million people. There are currently 33-35 megacities, depending on who is counting and who is being counted. This map looks at cities expected to reach megacity status by 2050: bucket.mlcdn.com/a/2764/2764870/images/0d7ca37bc55b1c8101a1a5e77cb243aae75162b2.jpeg

The U.S. Department of State and Google Maps are now on board with Turkey's request to spell the name of the country "Türkiye." (To make the necessary ü in Word, use control-: and then the u.)

This geo-graphic from Statista looks at "land grabs" in the developing world, defined as "the buying, leasing or concession land use for commercial purposes by companies from abroad, affecting land that had previously been used communally, by small-scale shareholders or was natural environment." (Until 2019, the country experiencing the most land grabs was Peru, but Peru is not on this list because it has been reclassified as an upper-middle income country.) cdn.statcdn.com/Infographic/images/normal/19044.jpeg

Working on behalf of a free press and the public's right to know is often a dangerous job.

Yes, climate change is making some natural disasters worse, but is it also becoming a tidy way of letting governments off the hook for bad planning?  The recent floods in Pakistan are a case in point. An international team of researchers analyzed the flooding in Pakistan and found that rainfall in the southern provinces of Sindh and Balochistan was "about 75% more intense than it would have been had the climate not warmed by 1.2C." But the report also found "The devastating impacts were also driven by the proximity of human settlements, infrastructure (homes, buildings, bridges), and agricultural land to flood plains, inadequate infrastructure, limited ex-ante risk reduction capacity, an outdated river management system, underlying vulnerabilities driven by high poverty rates and socioeconomic factors (e.g. gender, age, income, and education), and ongoing political and economic instability." Although solving climate change will remain out of the purview of any single country, that does not mean governments do not need to address in-country zoning, infrastructure, economic and political issues to mitigate the impacts of climate change. www.worldweatherattribution.org/climate-change-likely-increased-extreme-monsoon-rainfall-flooding-highly-vulnerable-communities-in-pakistan/

This topological map from Visual Capitalist shows the number and percentage of each country's population deemed to be at high risk from once-in-a-century flooding, like the floods that inundated more than one-third of Pakistan earlier this fall, killing more than 1,700 people, destroying buildings and crops, and creating lasting crises in food security, education, and waterborne disease. www.visualcapitalist.com/countries-highest-flood-risk/

The Chinese government has become one of the world's biggest lenders, especially to countries in the developing world and those associated with its Belt and Road Initiative. This map, from Statista based on World Bank data, shows which countries are most indebted to China: www.statista.com/chart/19642/external-loan-debt-to-china-by-country/

Americans often confuse the terms "monsoon" and "typhoon."  A monsoon is an annual rainy season; it is usually critical for life in the region.  A typhoon is a wind storm, like a hurricane, in the Pacific Ocean. The extreme flooding in the news in Pakistan is being caused by monsoon rains. Agriculture would be all but impossible in Pakistan without monsoon rains, but, unfortunately, this year's arrived earlier than normal and are falling more heavily than normal.  As of the last official U.N. count, nearly half a million homes in Pakistan have been damaged by the recent flooding and more than 1,000 people have died. This map, from the U.N., shows the damage is concentrated along the lower reaches of the Indus River. By the way, despite was you might read elsewhere, Pakistan cannot experience a typhoon: hurricane-like wind storms in the Indian Ocean are cyclones.  (Map from reliefweb.int/report/pakistan/pakistan-2022-monsoon-floods-situation-report-no-03-26-august-2022.)

This has been China's hottest, driest summer since record keeping began 61 years ago, and the impact on the Yangtze River has been severe, with tributaries dried up and water flow in the main branch running 50% below normal. The Yangtze is the longest river in the world that runs through only one country, and five of China's megacities -- cities with a population of at least 10 million -- are in the Yangtze River basin.  The Yangtze is not only a key source of water for drinking and irrigation, it is also a major source of hydroelectric power. In Sichuan Province, which gets 80% of its electricity from hydropower, factories have been shut recently to save power for home air conditioning. The next few days may also determine the impact on China's main rice crop. www.euronews.com/2022/08/21/china-declares-first-ever-drought-emergency-amid-intense-heatwave

Hal Brands, professor at the Johns Hopkins School of Advanced International Studies and former Special Assistant to the Secretary of Defense for Strategic Planning and lead writer for the Commission on the National Defense Strategy for the United States, released an important and somewhat contrarian new book this week arguing that China is likely to try to invade Taiwan within the next five years. Danger Zone lays out the case that far from being a rising power, China is a peaking power due to the convergence of a variety of serious demographic, economic, and geopolitical constraints, a situation that tends to make countries more reckless. "When you think about revisionist powers - so that's just a fancy political science word for countries that want to change the way the world works; they're dissatisfied with the existing order. They tend to become most aggressive, most rash, not when they are very confident about the future, when they think that things will be better a decade from now than they are now, but when they worry that their window to change the system is closing. That, either because their economy has stalled or they're becoming encircled by their enemies, or sometimes both, that they have a closing window of opportunity to achieve their objectives. And when that is the case, they become more prone to use coercion, to use violence, to use force to get what they want while they can still grab it. That's been the case historically in a variety of instances, from ancient times up to the 20th century. And it's the trap that we worry that China may be falling into today. ... [A] lot of the tailwinds that propelled China to where it is today have now become headwinds. Assets have become liabilities, so to speak." The book makes the argument for China's status as a peaking power and details what the U.S. and its allies can do, now, to head off possible Chinese aggression in the Pacific. (Quote from Brands' interview with the "Intelligence Matters" podcast: www.cbsnews.com/news/hal-brands-on-potential-of-future-conflict-with-china-intelligence-matters/.)

One of the terms my biogeography students learn is "extirpated," which means a species has gone extinct in part of its former range. India is undertaking a project to reverse extirpation: cheetahs are being reintroduced to Kuno National Park in north-central India. Cheetahs were extirpated from India more than 50 years ago. The cheetahs being reintroduced to India are African cheetahs; today, all that remains of the Asiatic cheetah that once roamed from India to the Arabian Peninsula is 12 individuals, 9 males and 3 females, in Iran. www.bbc.com/news/world-asia-india-62377387

Plants, animals, and microbes move around based on changes in the physical environment and human activity. This shifting geography was documented recently by the appearance in southern Mississippi of a dangerous microbe previously found only in tropical and subtropical zones, including northern Australia, parts of Central and South America, and South and Southeast Asia: www.nytimes.com/2022/07/27/health/deadly-bacteria-us-soil-water.html

Liquifying natural gas is a more expensive, energy-intense alternative to pipelines in the delivery of natural gas.  Several European countries are trying to bring more liquified natural gas (LNG) capacity online as quickly as possible to replace Russian, pipeline-delivered gas.

According to a new report from the United Nations, global population is projected to hit 8 billion on November 15 of this year, India is expected to surpass China as the world's most populous country in 2023, and more than half of global population growth between now and 2050 will be concentrated in just 8 countries (alphabetically): the DRC, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and Tanzania.
