Earlier in April, more than 60 million people were presented with a mission: Track down and vanquish a golden, fire-breathing dragon terrorizing a vulnerable village.That is, a digital village in the metaverse of Minecraft, a videogame that allows its many users to explore and build their own worlds.

Forget slaying dragons, the newest gaming trend is saving the virtual world (and maybe ours too).

Earlier in April, more than 60 million people were presented with a mission: Track down and vanquish a golden, fire-breathing dragon terrorizing a vulnerable village.

That is, a digital village in the metaverse of Minecraft, a videogame that allows its many users to explore and build their own worlds. In this new Minecraft minigame, “Heat Wave Survival,” players are facing up against the Heat Dragon, a villain developers created to represent the deadly threat of extreme heat as global temperatures rise.

This is just one of the many ways that climate change is infiltrating game night. Around the world, developers and designers are intentionally weaving climate change characters like the Heat Dragon, as well as potential solutions, into board games and video games to help engage users in the fight to slow global warming.

Today, we are exploring how the climate movement is growing within the gaming universe—and what that could mean for the real world.

Darwin Revisited: Modern Data Sheds Light on Ancient Evolutionary Theories

Ever since Darwin introduced his groundbreaking theory of evolution, biologists have been captivated by the complex processes that enable species to evolve. Can mechanisms responsible...

Researchers have demonstrated that the capacity for rapid adaptation within a few generations, known as evolvability, can also explain species divergence over millions of years. By analyzing extensive datasets from current species and fossils, they found that traits with high evolvability show more divergence over time, influenced by environmental fluctuations, which plays a crucial role in shaping evolutionary outcomes.Ever since Darwin introduced his groundbreaking theory of evolution, biologists have been captivated by the complex processes that enable species to evolve.Can mechanisms responsible for the evolution of a species over a few generations, called microevolution, also explain how species evolve over periods of time extending to thousands or millions of generations, also called macroevolution?A new paper, just published in Science, shows that the ability of populations to evolve and adapt over a few generations, called evolvability, effectively helps us understand how evolution works on much longer timescales. By compiling and analyzing huge datasets from existing species as well as from fossils, the researchers were able to show that the evolvability responsible for microevolution of many different traits predicts the amount of change observed between populations and species separated by up to one million years.“Darwin suggested that species gradually evolve, but what we found is that even though populations rapidly evolve over the short term, this (short-term) evolution doesn’t accumulate over time. However, how divergent populations and species are, on average, over long periods of time still depends on their ability to evolve in the short term,” said Christophe Pélabon, a professor at NTNU’s Department of Biology and senior author of the paper.Big datasets from living creatures and fossilsThe ability to respond to selection and to adapt, the evolvability, depends on the amount of heritable (genetic) variation. The researchers conducted their analysis by first compiling a massive dataset with measures of evolvability for living populations and species from publicly available information. They then plotted evolvability against population and species divergence for different traits such as beak size, number of offspring, flower size and more.They also examined information from 150 different lineages of fossils, where other researchers had measured differences in morphological traits in the fossils over time periods as short as 10 years and as long as 7.6 million years.Darwin noted how different finches from the Galapagos Islands developed different kinds of beaks, based on the food that they specialized in eating. Later studies showed how rapid fluctuations in seed size over time led to rapid fluctuations in beak size, just as suggested by the new study, published in Science. This illustration is from Darwin, 1845. Journal of researches into the natural history and geology of the countries visited during the voyage of H.M.S. Beagle round the world, under the Command of Capt. Fitz Roy, R.N. 2d edition. Credit: John GouldWhat they saw was that traits with higher evolvability were more divergent among existing populations and species, and that traits with higher evolvability were more likely to be different from each other between two consecutive fossil samples.Conversely, traits with little evolvability or little variability didn’t change very much between populations or between successive fossil samplesEnvironmental fluctuation is the keyTraits with higher evolvability change rapidly because they are able to respond to environmental changes more quickly, Pélabon said.The environment – things such as temperature, the type of food available, or any other characteristic important for the survival and the reproduction of the individual – is the driving force of evolutionary changes because populations try to adapt to their own environment. Typically, environments are changing from year-to-year or decades-to-decades, fluctuating around stable means. This generates fluctuation in the direction of selection.Highly evolvable traits can rapidly respond to these fluctuations in selection and will fluctuate over time with high amplitude. Traits with little evolvability will also fluctuate but more slowly and thus with lower amplitude.“Populations, or species, that are geographically distant from each other are exposed to environments whose fluctuations are not synchronized. Consequently, these populations will have different trait values, and the size of this difference will depend on the amplitude of the trait’s fluctuation, and therefore on the evolvability of the trait,” Pélabon said.Consequences for biodiversityThe researchers’ results suggest that selection and therefore the environment has been relatively stable in the past. With climate change, things are rapidly changing, and mostly in one direction. This may strongly affect patterns of selection and how species can adapt to environments that are still fluctuating but around optima that are no longer stable even over periods of time of a few decades.“How much species will be able to track these optima and adapt is uncertain, but most likely this will have consequences for biodiversity, even on a short timescale,” he said.Reference: “Evolvability predicts macroevolution under fluctuating selection” by Agnes Holstad, Kjetil L.

Top scientists urge action against faeces in rivers

A team of Royal Academy of Engineering scientists say the risk from human faeces is increasing.

Top scientists urge action against faeces in riversJust nowEsme Stallard,Climate and science reporter, BBC NewsBBCHuman faeces in our rivers is putting the public in danger and the risk will increase without action, the UK's top engineers and scientists have warned in a report.The report led by the Royal Society of Engineering called for an upgrade of the UK's sewage system and more widespread testing of the country's waterways.Prof Chris Whitty - the UK's chief medical officer - said it was a "public health priority as well as an environmental one".The government said the largest infrastructure programme in water company history was currently taking place.Despite improvements in the UK's water quality, raw sewage overflowing into rivers and seas is a persistent problem. Last year on average there were 1,271 spills a day in England - a doubling on the previous year. Less than a week ago, thousands of residents in Devon had to resort to drinking bottled water after their supply was polluted with the parasite Cryptosporidium apparently because of a faulty valve in Southwest Water's network. Professor Barbara Evans, chair of public health engineering at the University of Leeds and one of the study's co-authors, told the BBC: "One of the most dangerous things in our lives is human faecal waste."She said: "We now know that more of [this waste] is going back into the environment. And we know that more people want to use bathing waters."So we have to say that there's an increased risk of an outbreak of infectious faecal oral disease."Consumption of water contaminated with human faeces exposes people to bacteria such as salmonella and E.coli which cause diarrhoea and vomiting or viruses like hepatitis A which can lead to liver infection.PAThe report said testing was more important than ever as more people took part in leisure activities in the UK's seas and riversMelissa Compton, 44, a nurse from Shrewsbury, regularly swims in the sea near her home in Anglesey and in the River Severn.She told the BBC it was really important for the public to be able to swim and enjoy the UK's rivers."I love it - it's a freedom that I get. Kids play in the river, people fish, and the wildlife really depends on it. It's part of life."But she knows the risks of contact with sewage pollution after being brought to hospital whilst taking part in a 220-mile charity swim in the River Severn."What I was swimming through was just awful, sickly, slightly grey in colour and it just stank."She now uses the Surfers against Sewage maps to know when sewage has been released.Melissa ComptonMelissa Compton had hospital treatment after "swallowing raw sewage" whilst swimming the length of the River SevernThe report recommends that any data from more regular testing of the rivers should be made available to the public so they can keep themselves safe. Currently this is only undertaken regularly by the Environment Agency at designated bathing water sites.The government announced last week that England will get 12 more official bathing sites along rivers taking the total to 15.And a spokesperson for the water company trade association Water UK said: "Water companies have a plan with proposals to double the current level of spending between now and 2030 "with bathing areas heavily prioritised for investment".The report puts forward 15 recommendations including to:Improve maintenance of the existing sewage networkReturn to collecting widespread data on faecal bacteriaReview the current regulations on bathing waterDevelop a long-term strategy for better designing cities to reduce floodingCharles Watson, chair of River Action UK, said it was a "brilliant piece of work, produced by some of the most authoritative people in the medical and engineering professions".He particularly welcomed their call to expand testing for bacteria and viruses from faeces. When asked what could be the impact of not implementing these recommendations he said: "someone will die."The scientists said upgrading infrastructure such as the Thames Tideway Tunnel project is just one part of the solutionThe authors were keen to stress that the government should not just focus on improving infrastructure - which would reduce the short-term health risk - but a longer-term vision for how the UK's cities are designed.Since 1950 the UK's population has grown by a third and cities and towns have continued to expand, paving over natural landscapes. This has increased the volume of water running off into the sewage system - increasing the pressure on the old infrastructure.Prof David Butler, chair of the National Engineering Policy Centre working group on wastewater, explained that the system would become only more strained."Growing urbanisation and forecasts for more frequent and intense rainfall events due to climate change will mean increasing pressure is put on our ageing wastewater system," he said.The experts recommended increasing rainwater collection, expanding natural environments like wetlands and installing smart water meters. These would all help to reduce the amount of water and sewage going into the network.In May the government announced it was awarding £11.5m to local projects to increase tree planting and restoring habitats like the Limestone Becks, which would help absorb excess rainfall and run off.

Bird populations in the Amazon are declining without clear cause

Bird populations in the Amazon's Yasuní Biosphere Reserve have mysteriously dropped by half over 23 years, with climate change being a potential culprit.Bernardo Araujo reports for Mongabay.In short:The number of birds in Ecuador's Yasuní Biosphere Reserve has halved, according to a recent study.Researchers suspect climate change as the primary cause, despite the area being largely undisturbed by human activity.Similar declines have been observed in other tropical regions, indicating a broader environmental issue.Key quote: “There’s something called the dawn chorus, which is typical in tropical forests where lots of birds sing just before dawn. And over the last 10 years, that has just been going quieter and quieter with very few birds singing in the morning.”— John Blake, University of Florida professorWhy this matters: This decline in bird populations, even in pristine habitats, is indicative of the far-reaching impacts of climate change, raising alarms about the future of biodiversity in tropical ecosystems.

Politicians avoid discussing climate change during Indian elections

As India’s general elections approach, voters are facing climate-related hardships that politicians largely ignore.Sibi Arasu reports for the Associated Press.In short:Extreme heat and drought in Maharashtra state have left farmers struggling, with no substantial political focus on environmental issues.Increased cyclones along India’s eastern coasts have caused significant damage and deaths, with locals frustrated by unfulfilled political promises.Floods in Assam state are worsening, leaving residents on river islands vulnerable and dissatisfied with political inaction.Key quote: “Politicians are only talking about religion and caste. No one is talking about the environment or farmers' issues.” — Vaibhav Maske, farmer in MaharashtraWhy this matters: Ignoring climate change in political discourse undermines efforts to address its severe impacts on health, livelihoods, and regional stability. Effective policies are needed to protect communities from increasingly extreme weather events. Read more: Sabah Usmani on making cities healthy and just.
