Apr 27 · As the sun sets on another scorching Yangon day, the hot and bothered descend on the Myanmar city's parks, the coolest place to spend an evening during yet another power blackout.
A wave of exceptionally hot weather has blasted Southeast Asia this week, sending the mercury to 45 degrees Celsius (113 degrees Fahrenheit) and prompting thousands of schools to suspend in-person classes.
Even before the chaos and conflict unleashed by the military's 2021 coup, Myanmar's creaky and outdated electricity grid struggled to keep fans whirling and air conditioners humming during the hot season.

| 2024 SkS Weekly Climate Change & Global Warming News Roundup #17 - Skeptical Science |
Apr 28 · Anthropogenic climate change may be the ultimate shaggy dog story— but with a twist, because here endless subplots definitely depend upon one central element in the unfolding drama of our grand physics accident: the dominant story mechanic is that we're changing Earth's climate. This leads to outcomes. One way of seeing this is via the abstraction of statistics, while another perspective is that of individual experiences each of which is only an anecdote but together lead us back to statistics. Our story of the week is Carbon Brief's annual summary State of the climate: 2024 off to a record-warm start:

| A strategy to boost the efficiency of perovskite/organic solar cells - PHYS.ORG - Technology |
Apr 28 · So far, organic solar cells have achieved a maximum certified power conversion efficiency (PCE) of 19.4%, which is lower than that exhibited by silicon solar cells. A proposed strategy to boost their efficiency and stability entails combining these cells with cells based on mixed halide wide-bandgap perovskites, creating perovskite/organic tandem solar cells.
While perovskite/organic tandem solar cells could theoretically achieve high PCEs and stabilities, their performance is hindered by a process known as phase segregation. This process degrades the performance of wide-bandgap perovskite cells and in turn adversely affects recombination processes at the tandem solar cells' ... Read more ...

Apr 29 · From ancient fertilizer methods in Zimbabwe to new greenhouse technology in Somalia, farmers across the heavily agriculture-reliant African continent are looking to the past and future to respond to climate change.
Africa, with the world's youngest population, faces the worst effects of a warming planet while contributing the least to the problem. Farmers are scrambling to make sure the booming population is fed.
With over 60% of the world's uncultivated land, Africa should be able to feed itself, some experts say. And yet three in four people across the continent cannot afford a healthy diet, according to a report last year by the African Union and United Nations ... Read more ...

Apr 29 · On June 19, southern Mobile County, Ala., experienced torrential rain and severe flooding. Roads and some homes near the Fowl River were submerged.
But this was no ordinary flood.
THEODORE, Ala.
John Corideo drove the solitary two-lane highways of southern Alabama, eyeing the roadside ditches. It had been raining off and on for days and Corideo, chief of the Fowl River Fire District, knew that if it continued, his department could be outmatched by floodwaters.
It kept raining. Water filled the ditches and climbed over roads, swallowing parts of a main highway. About 10 residents who needed to be rescued were brought back to the station in firetrucks. More ... Read more ...

Apr 24 · Fire management lessons from the past could help to improve resilience as the Mediterranean faces increased fire risk from climate change. University of California, Santa Cruz Anthropology Professor Andrew Mathews shows how traditional land management practices once greatly reduced fuel for wildfires, and how these practices were forgotten, in part due to historical politics of classism and sexism.
In the last several decades, large forest fires have increasingly threatened communities across the Mediterranean. Climate change is expected to make these fires larger, hotter, and more dangerous in the future. But fire management lessons from the past could help to improve the ... Read more ...

Apr 24 · As the climate changes, animals are doing what they can to adapt.
Over the past century, white-tailed deer have greatly expanded their range in North America, explains Melanie Dickie, a doctoral student with UBC Okanagan's Wildlife Restoration Ecology Lab.
In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north. Climate change can create milder winters, while habitat alteration from forestry and energy exploration creates new food sources for deer.
As they conclude their study, researchers caution that what is good for the deer isn't necessarily suitable ... Read more ...

And while plastic was once hailed as a miracle product, we now know the damage plastic pollution does to ecosystems, the climate, human health and the economy.\n\nCentral to ending plastic pollution is the elimination of unnecessary plastic, the redesign of products – including packaging – so they can be more easily reused, repaired and recycled, and switching to non-plastic substitutes that help protect the environment, human health, and our economy. \n\nSo, it's time to write a new story and ... | By United Nations Read more ...

| Finding space for wind farms might be easier than we thought - Washington Post - Climate and Environment |
Apr 28 · Towering wind turbines dot landscapes across the country, stretching hundreds of feet into the sky. But the huge structures topped with massive rotating blades only take up five percent of the land where they’ve been built, new research shows.
The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology.
This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.

Apr 28 · But over the last four years, even as the hole has shrunk it has persisted for an unusually long time. Our new research found that instead of closing up during November it has stayed open well into December. This is early summer—the crucial period of new plant growth in coastal Antarctica and the peak breeding season for penguins and seals.
That's a worry. When the ozone hole forms, more ultraviolet rays get through the atmosphere. And while penguins and seals have protective covering, their young may be more vulnerable.

Apr 24 · Whether you're trying to predict a climate catastrophe or mental health crisis, mathematics tells us to look for fluctuations.
Changes in data, from wildlife population to anxiety levels, can be an early warning signal that a system is reaching a critical threshold, known as a tipping point, in which those changes may accelerate or even become irreversible.
But which data points matter most? And which are simply just noise?
A new algorithm developed by University at Buffalo researchers can identify the most predictive data points that a tipping point is near. Detailed in Nature Communications, this theoretical framework uses the power of stochastic differential ... Read more ...

| Pinning down climate change's role in extreme weather - Skeptical Science |
Apr 29 · In the wake of any unusual weather event, someone inevitably asks, “Did climate change cause this?” In the most literal sense, that answer is almost always no. Climate change is never the sole cause of hurricanes, heat waves, droughts, or any other disaster, because weather variability always plays a primary role in the genesis of the events.
However, climate change can make these events more intense and, given the non-linearities in the damages, this can vastly increase the damage and misery from extreme weather. So quantifying the role of climate change is therefore of great interest.
To do this, scientists turn to extreme event attribution studies. These ... Read more ...

The term symbiosis was first used in the 19th century to describe the lichen relationship, which was thought to be highly unusual. Since then, we've discovered symbiosis is the norm, rather than the exception. In fact, it has shaped the evolution of most life on Earth.
