Various technological methods/techniques are being developed not only to slash/control the emission of carbon dioxide but also to make its use from its ever-increasing atmospheric concentration through direct-air capture of atmospheric carbon. The projects have their importance as many climate experts warn that current measures to reduce emissions-such as adopting renewable energy and electrifying transportation-are no longer sufficient to avert catastrophe. To limit global warming to 1.5 °C, the world must also use “negative-emission technologies,” according to the United Nations Intergovernmental Panel on Climate Change’s2018 report. Global CO2 emissions from fossil fuels reached 33 billion metric tons in 2019.
A facility at west Texas (USA) with rows of giant fans spread across a flat, arid field will pull carbon dioxide from the air and then pump it deep underground. When completed, the project could capture 1 million metric tons of carbon dioxide per year, doing the air-scrubbing work of some 40 million trees.

Building world's 1st pyramid
In a preprint study published this summer, researchers proposed that ancient Egyptians built the world's first pyramid the 4,700-year-old Step Pyramid of Djoser, which sits on Egypt's Saqqara plateau using a \"modern hydraulic system\" powered by a long-gone branch of the Nile River.
Climate change arms the world, ovarian cancer pulls the trigger.It's time we disarm them both
Climate change, driven by human activities, leads to environmental changes such as rising temperatures, altered weather patterns, and increased pollution.
Climate Change Added 18 mph to Hurricane Wind Speeds over Past 5 Years
High ocean temperatures caused by global warming boosted maximum intensities for most storms between 2019 and 2023, as well as for every 2024 hurricane.
How Indian Vulture Decline Led to 500,000 Deaths in 5 Years
Once a common sight across India, vultures were abundant scavengers, often seen circling landfills in search of carcasses.
Understanding Monkeypox: Insights and Implications
Monkeypox, a viral zoonotic disease, has gained significant attention in recent years due to its re-emergence and sporadic outbreaks globally.
AI predicts that most of the world will see temperatures rise to 3°C much faster than previously expected
Three leading climate scientists have combined insights from 10 global climate models and, with the help of artificial intelligence (AI), conclude that regional warming thresholds are likely to be reached faster than previously estimated.
Infrared Radiation: A New Player In Mosquito Host-Seeking
The sound of mosquitoes is all around us when the sun sets and the air gets warm and sweltering.
Fish Oil May Benefit to Cure Alzheimer's, disorder: new findings
The benefits of fish and fish oil consumption are well-known in medical science as fish is considered a precious food resource that provides sufficient nutrition to humans.
A new class of antivirals could help prevent future pandemics
The arrival of Paxlovid in December 2021 marked another turning point in the COVID-19 pandemic an effective antiviral that has since successfully treated millions.
Turning carbon emissions into methane fuel
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.
