Climate Change
Phys.org, 2021-10-27
If nations make good on their latest promises to reduce emissions by 2030, the planet will warm by at least 2.7℃ this century, a report by the United Nations Environment Programme (UNEP) has found. This overshoots the crucial internationally agreed temperature rise of 1.5℃.

The Clark Fork River drains much of western Montana, bringing water from the Crown of the Continent to the Columbia River and the Pacific Ocean. My daily commute via bicycle crosses the Clark Fork most days and has allowed me to discern a rhythm and tempo in how the seasons come and go—a composition of daily weatherlike notes in a musical score that is the climate of Missoula, Montana.

Weather extremes can cause economic ripples along supply chains. If they occur at roughly the same time, the ripples start interacting and can amplify, even if they occur at completely different places around the world, a new study shows. The resulting economic losses are greater than the sum of the initial events, the researchers find in computer simulations of the global economic network.

Analysis of countries' plans to fight climate change show they are not enough to avoid the worst impacts unless further promises are kept.
Phys.org, 2021-10-27
The forests, grasslands and coastal and marine ecosystems that Fauna & Flora International (FFI) and partners are working to safeguard are not just biodiversity havens. They also play a vital role in the global carbon cycle by removing it from the atmosphere and storing it for decades, centuries, or even millennia.

As a major U.N. climate conference gets underway on Oct. 31, 2021, you'll be hearing a lot of technical terms tossed around: mitigation, carbon neutral, sustainable development. The language can feel overwhelming.

'Climate change is becoming an increasingly serious driver of biodiversity loss and ecosystems degradation – and that loss threatens to worsen climate change," Elizabeth Maruma Mrema says
The Conversation, 2021-10-27
More than half of the world’s 7.8 billion people live in cities and urban areas. By 2050, an additional 2.5 billion will be living there. As that figure continues to climb and ever more people flock to metropolitan areas in the hope of a better life, the big question is: how do we fit everyone in?

In a report issued ahead of the UN climate conference opening in Glasgow on Sunday, the International Fund for Agricultural Development (IFAD) sounded the alarm after commissioning a study on agriculture in southern and eastern Africa.
Agriculture and Biodiversity
Phys.org, 2021-10-27
That cow may look peaceful and harmless, munching on some grass in a verdant pasture. But don't be fooled—it is emitting methane, a particularly potent greenhouse gas contributing to runaway global climate change.

As a result of increased agricultural activity brought about by the expansion of the wine industry, the biodiversity of the floral kingdom is under threat in the Cape Winelands. A conservation programme by the WWF is now helping to ensure that wine farms decrease their impact on the environment.
Guardian (International Edition), 2021-10-27
About a third of human-caused methane emissions come from livestock, mostly from beef and dairy cattle, produced in the digestive process that allows ruminants (hoofed animals including cows, sheep and goats with four-part stomachs) to absorb plants.
Chemicals and Pollution
Deutsche Welle, 2021-10-27
Environmentalists fear pollution from the Gonio landfill is seeping into the air, soil and waters of the Black Sea. But government plans to close it have left many waste pickers worrying about an uncertain future.

Most Africans have heard of climate change and agree that it should be stopped. But far fewer feel that ordinary people can do something to stop it and even fewer understand its human causes.
Forest Biodiversity
New Statesman (UK), 2021-10-27
My earliest memories are of coins of sunlight falling through feathery branches, from the time when my mother put me under trees for naps. The play of light through the shifting leaves and green-tinted air established my life-long ideal of beauty. Southern New Hampshire, where I now live, is an Appalachian forest made up of oak, hickory, ash and some maple and pine.

Knowing the steps is not the same thing as knowing how to dance. Similarly, policy interventions to stop deforestation are most effective when enacted in a certain order, according to a new Stanford study.
CBC (Canada), 2021-10-27
The historical pattern holds true with past agreements struck in Rio, Kyoto and Copenhagen. To meet the Paris target and the federal government's revised target unveiled this summer, considerable change is necessary.
Migratory Species

The annual migration of birds from the Arctic to the Gulf of Mannar Marine Biosphere Reserve, has begun with an enormous flock seen swarming the Manoli Islands inside the park last weekend.

The sound of an accelerating heartbeat can instantly send chills down your spine. You know that sound means trouble. We are so accustomed to the way our hearts seem to continuously mirror how we feel that we can easily imagine different hearts racing, aching or skipping a beat.

The fruit fly, long the organism of choice for scientists studying genetics and basic biological processes, still harbors some secrets of its own.

A colony of wild monkeys in Dania Beach soon may get a permanent home, complete with fences, medical care and regular meals. But the creation of a monkey sanctuary east of the Fort Lauderdale airport may mark the beginning of the end of a bizarre wildlife population that has survived on a wedge of swampy forest for more than 70 years.

The task of training an effective cadre of biodiversity scientists has grown more challenging in recent years, as foundational skills and knowledge in organismal biology have increasingly required complementary data skills and knowledge. Writing in BioScience, Dr. Anna K. Monfils, of Central Michigan University, and colleagues identify one way to address this training conundrum: biodiversity collections.

Archaea are often mistaken as bacteria, given that both are small, single-cell organisms. However, archaea are as genetically different from bacteria as humans are from bacteria. While archaea are found in most environments, including the human gut microbiome, relatively little is known about them. An international team of researchers from Germany and Austria, led by Nicholas Youngblut at the Max Planck Institute for Developmental Biology in Tübingen, Germany, has compiled the first large scale assessment of archaeal diversity in the vertebrate gut.

World-first research testing a simulated 'shark vision' model on swimming patterns of humans, seals and sea-lions, confirms theories that when great white sharks bite humans, it may be a case of mistaken identity.
Phys.org, 2021-10-27
New work led by Carnegie's Kangmei Zhao and Sue Rhee reveals a new mechanism by which plants are able to rapidly activate defenses against bacterial infections. This understanding could inspire efforts to improve crop yields and combat global hunger.

In the heyday of the Ein Gedi spa in the 1960s, holidaymakers could marinate in heated pools and then slip into the briny Dead Sea. Now the same beach is punctured by craters.

American bison narrowly escaped extinction due to overhunting in the 19th century, but their populations have since rebounded thanks to modern conservation efforts. Today, bison are increasingly being reintroduced to new areas of their historic range. Many of these areas provide important nesting habitat for grassland birds, which are now among the most rapidly declining birds in North America.

In many branches of natural science, research findings are communicated through peer-reviewed technical papers. In most cases, the titles of the papers are optimised to be factually accurate and to keep away (and not waste time) of all but those who are sure to be interested in their contents. Such a practice fosters the rapid progress of science in predetermined directions – but could impede the cross-fertilisation of ideas across disciplines.

For coffee drinkers, there’s nothing like that first sip in the morning. For Tulane University researchers studying the sustainability of coffee in Honduras, the stakes are far higher than a tempting cup of joe.

It’s been three decades since the Ugandan government evicted the Batwa people, an Indigenous group commonly known as Pygmies, from their forest lands. The reason for their displacement was to create national parks aimed at protecting biodiversity and promoting tourism.
