How to Cool the Planet by Capturing Contrails | Dr Sarah Qureshi | TEDxFaisalabad Medical University
TEDx Talks· 2025-07-11 16:22
Aviation Industry & Environmental Impact - Aviation industry faces the challenge of reducing pollution, specifically moving from zero carbon (no CO2 emissions) to zero emissions (no CO2 and non-carbon emissions) [5][6] - Burning hydrocarbon fuel produces both carbon dioxide and water vapor, with water vapor behaving as a greenhouse gas in the atmosphere [4] - Contrails, or condensation trails, are artificial clouds formed by the freezing of water vapor released from aircraft engines, contributing to global warming by creating a heat-trapping blanket [6][7][10] - Contrails cover is increasing, with projections showing a significant rise in artificial cloud coverage by 2050 compared to 1992 [13] - Aviation's annual fuel burn is 4 billion tons, releasing 5 billion tons of water vapor, with 50% (2.5 billion tons) forming contrails, disrupting the earth's ecosystem [14] - Global warming heat signature from contrails is equivalent to 1 trillion watts, which is one-third of the world's annual electricity consumption [11] Technological Solutions & Innovation - Various technologies are being explored to reduce aviation pollution, including hybrid-electric, all-electric, liquid hydrogen burning, hydrogen fuel cells, ammonia fuel combustion, and sustainable aviation fuels [15][16][17] - Battery technology limitations hinder the development of large-scale electric aircraft, necessitating a combination of technologies [17][18] - A company has developed an add-on turbo machinery for jet engines to process exhaust emissions, converting water vapor into liquid water for later release as artificial rainfall, aiming to eliminate contrails [19][22] - The company's technology is at Technology Readiness Level (TRL) stages, progressing from basic concept and simulation (TRL 1-3) to lab testing (TRL 4-5) and eventually flight testing (TRL 9) for commercialization [26][27] Business & Market Strategy - The company aims to provide an alternate technology to reduce pollution in the sky, enabling regulations on emissions of smoke [34] - The company targets engine manufacturers, aircraft manufacturers, and airlines as potential adopters of its contrail-free engine technology [29][31] - Airlines can potentially create artificial rainfall, obtain carbon credits, and support environmental agencies' regulations by adopting the technology [34]

The answer is soil | Chris Huskins | TEDxWinchester
TEDx Talks· 2025-07-01 16:58
Environmental Concerns & Challenges - Soil depletion poses a significant threat, potentially rendering soils unable to grow food within 60 years [1] - Conventional agricultural practices, including plowing and chemical use, degrade soil health, leading to dust storms, floods, and rising food prices [2][5] - Degraded soils lose their capacity to hold water and store carbon, exacerbating climate change and food insecurity [5] - Over the past 70 years, the nutritional content of fruits and vegetables has decreased significantly due to soil degradation [6] Solutions & Regenerative Practices - Healthy soil, teeming with microorganisms, can sequester carbon, filter water, and provide essential nutrients for food production [4][5] - Regenerative agriculture practices, such as no-till farming, cover cropping, and livestock integration, can restore soil health and ecosystem function [10] - Gabe Brown's farm serves as a successful example of how regenerative practices can revitalize degraded land and enhance resilience to extreme weather [11] - Beavers can act as natural water engineers, creating wetlands that boost biodiversity and replenish soil [13][14] Call to Action - Supporting farmers who employ regenerative or organic practices is crucial for promoting soil restoration [17] - Governments should prioritize funding soil restoration initiatives over destructive agricultural practices [17] - Recognizing soil as the foundation of life and educating future generations about its importance is essential for ensuring a sustainable future [18]
Investors are rethinking infrastructure as the climate changes
CNBC Television· 2025-07-01 15:01
At Fort Lauderdale International Airport, historic rainfall turned runways into rivers, shutting it down and stranding passengers. And in New York City, extreme heat caused metal on this bridge to expand so much that the bridge got stuck open. US infrastructure can't handle climate change.That's a recent finding by the American Society of Civil Engineers, which trains engineers and informs federal, state, and local building codes. According to that report, climate related challenges are widespread, affectin ...

Globenewswire· 2025-07-01 11:30
Core Points - Watsco, Inc. has declared a quarterly cash dividend of $3.00 per share, marking the 200th consecutive quarter of dividend payments [1][2] - The company has a history of paying dividends for 51 consecutive years, reflecting its commitment to sharing cash flow while maintaining a conservative balance sheet [2] - Watsco focuses on the replacement market for HVAC/R products, which is growing due to aging systems and the need for energy-efficient models [4] Company Overview - Watsco is the largest distributor of heating, air conditioning, and refrigeration products in the U.S., Canada, Mexico, and Puerto Rico, with exports to Latin America and the Caribbean [3] - The company plays a significant role in addressing climate change by promoting the replacement of older HVAC systems with higher efficiency models [5] Market Opportunity - There are approximately 102 million HVAC systems in the U.S. that are over 10 years old, many of which operate below current efficiency standards, presenting a substantial market opportunity for Watsco [4] - From January 1, 2020, to March 31, 2025, Watsco is estimated to have averted 23.7 million metric tons of CO2e emissions through the sale of higher-efficiency HVAC systems, equivalent to removing 5.5 million gas-powered vehicles from the road annually [6]
Who Owns Our Wealth? The hidden past and urgent future of money | Felix Oldenburg | TEDxBerlin
TEDx Talks· 2025-06-24 16:57
Problem Statement & Financial Analysis - The cost of inaction on climate change is estimated to exceed $1.3 quadrillion (1,266 trillion dollars) by 2100, which is 10 times global GDP [4] - In Germany, there is a 30 billion euro gap of philanthropic potential [16] - Foundations in Germany, with endowments between 100 and 200 billion euro, give away only about 1% annually [13][14] - Mobilizing 1% of income or wealth in Germany could generate 100 billion euro per year, a ten-fold increase over current giving levels [23] Wealth Management & Philanthropy - A significant portion of wealth in developed economies is inherited, often with family expectations to preserve it for future generations [7] - Financial gatekeepers (bankers, tax advisors, family officers) are incentivized to protect and grow wealth, not necessarily to invest it for social good or facilitate giving [9] - Legal instruments like trusts and foundations, while originally intended for protection and preservation, have become part of a global wealth defense industry, locking up money with tax privileges and secrecy [12][13] - Traditional foundations often invest in harmful industries due to low-risk, market-return investment strategies [14] Solutions & Future Trends - Modern giving can be revolutionized by using the internet to reduce costs, replace gatekeepers, and allow broader participation [20] - Digital foundations can enable anyone to start one with any amount of money, facilitating strategic giving, impact investing, and fundraising [21] - Shifting from a blame game to a model where everyone can be a philanthropist, impact investor, or influencer is crucial [25] - Encouraging individuals to give just 1% of their income or wealth can create significant positive change [22]
What If the Key to Saving Earth Is Building on Mars? | Christos Athanasiou | TEDxAtlanta
TEDx Talks· 2025-06-16 16:45
I want you to close your eyes and imagine you're standing on a quiet beach. The waves are touching your feet. Only this time, the beach is gone.The oceans have crept into cities, swallowed islands, and rewritten the map of our world. Rising sea levels fueled by surging temperatures are not a distant threat. They are already here.And as we wrestle with this growing problem, let me ask you, what if the answer isn't only here on Earth. What if our hope, our survival, maybe even the next great story of humans i ...
