School strike for climate International youth movement for climate action The school strike for climate (Swedish: Skolstrejk för klimatet), also known variously as Fridays for Future (FFF), Youth for Climate, Climate Strike or Youth Strike for Climate, is an international movement of school students who skip Fridays classes to participate in demonstrations to demand action from political leaders to take action to prevent climate change and for the fossil fuel industry to transition to renewable energy. Publicity and widespread organising began after Swedish pupil Greta Thunberg staged a protest in August 2018 outside the Swedish Riksdag (parliament), holding a sign that read "Skolstrejk för klimatet" ("School strike for climate").[4][5] A global strike on 15 March 2019 gathered more than one million strikers in 2,200 strikes organised in 125 countries.[1][6][7][8] On 24 May 2019, the second global strike took place, in which 1,600 events across 150 countries drew hundreds of thousands of protesters.

Researchers come up with machines that harness power of evaporating water | Uncover Michigan Researchers have come up with two new units that are directly powered by evaporation. The units have been developed by scientists from Columbia University. They created a floating, piston-driven engine that produced electrical energy to power a flashing mild and a rotary engine, which propels a small automotive. According to Ozgur Sahin, an affiliate professor of organic sciences and physics on the Columbia University and the lead writer of the research, water has a fixed conversion and it is required to use power from evaporation; it is very highly effective, but it has not been harnessed until now. According to the Columbia University bioengineer, "Evaporation is a ubiquitous phenomenon within the pure setting and a dominant type of power switch within the Earth's local weather. Evaporation produces the energy that drives the 2 engines; it is generated through distinctive bacterial spores that increase and contract as humidity ranges vary.
Greta Thunberg Swedish environmental activist (born 2003) Greta Tintin Eleonora Ernman Thunberg (Swedish pronunciation: [ˈɡrêːta ˈtʉ̂ːnbærj] ; born 3 January 2003) is a Swedish environmental activist known for challenging world leaders to take immediate action for climate change mitigation.[1] Thunberg's climate activism began when she persuaded her parents to adopt lifestyle choices that reduced her family's carbon footprint. At age 15, Thunberg began skipping school on 20 August 2018, vowing to remain out of school until after the national Swedish election in an attempt to influence the outcome. After Thunberg graduated from high school in June 2023, her protest tactics began to escalate.[17] As an adult, her protests have included defying lawful orders to disperse—and peaceful but defiant confrontations with police—which have led to arrests and convictions.[18] Thunberg's activism has also evolved to include causes other than climate change, most notably the Israel–Hamas war.

Bladeless bird friendly turbine Does a wind turbine have to have one of those pinwheel-looking blades that spins around to be called a turbine? It depends what definition you go by. Meet the Vortex Bladeless, a wind ‘turbine’ without blades, developed by a group of inventors at a Spanish tech startup. This new wind energy solution looks more like a giant golf tee then a wind turbine. Its inventors — David Suriol, David Yáñez and Raul Martín — describe it as “[a] more efficient, cost-effective, and environmentally friendly way to produce energy.” It has no moving parts, so how does it work? Vortex Bladeless explains: “Our device captures the energy of vorticity. How does this new wind energy solution compare to traditional wind turbines? Sounds promising, but is it improving upon traditional turbines or just offering another way to accomplish the same thing? According to Vortex Bladeless, it’s technology saves 53 percent in manufacturing costs and 51 percent in operating costs compared to conventional wind turbines.
History of climate change science Aspect of the history of science The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. John Tyndall was the first to measure the infrared absorption and emission of various gases and vapors. In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. By the 1990s, as the result of improving the accuracy of computer models and observational work confirming the Milankovitch theory of the ice ages, a consensus position formed. Since the 1990s, scientific research on climate change has included multiple disciplines and has expanded. Prior to the 20th century[edit] Regional changes, antiquity through 19th century[edit] T.

Curious Kids: How do plastic bags harm our environment and sea life? This is an article from Curious Kids, a series for children. The Conversation is asking kids to send in questions they’d like an expert to answer. All questions are welcome – serious, weird or wacky! You might also like the podcast Imagine This, a co-production between ABC KIDS listen and The Conversation, based on Curious Kids. My name is Sanuki and I’m 8 years old. Good question, Sanuki! Plastic bags harm marine (and land) environments in a few ways. Turtles (and other animals) may mistake plastic bags for food. When turtles eat plastic, it can block their intestinal system (their guts).

On land, plastic bags are an eyesore. Many people don’t realise that plastic bags can also cause flooding. Making plastic requires a lot of energy and work Plastic bags can even be harmful before they are used. The push towards plastic-free
