Planting the Future: Local Actions in a Global Climate Crisis | Dr. Umar Aminu Mohammed | TEDxSAZU
TEDx Talks· 2025-12-03 16:58
Climate Change Impact - Global warming has led to a 12% increase in temperature compared to 150 years ago, resulting in flooding, seasonal fluctuation, drought, and deforestation [3][4] - The Intergovernmental Panel on Climate Change projects a potential 15% increase in global average temperature by 2030, affecting the lives of 350 million individuals [4] - Northern Nigeria faces desertification, with 60 meters of desert encroaching southwards annually, impacting livelihoods and the Lake Chad Basin, where 90% has shrunk [6] Mitigation Efforts - Sahongur University has planted 1,000 trees, with each mature tree capable of absorbing 22 kilograms of carbon dioxide per year [5] - Nature-based solutions, such as planting and sustaining trees, are crucial for addressing climate change [8] - Integrating climate literacy into education curricula is essential [9] Call to Action - Collaborative efforts are needed to enhance the sustainability of planted trees [8] - Policymakers should recognize climate change as an important issue [9] - The best time to plant a tree was 20 years ago, and the second best time is today, emphasizing the urgency of action [10]

Climate Change Overview - Global warming and climate change pose a major threat to global society, particularly future generations [1] - The global mean temperature has increased by 1°C (1 degree Celsius) in the last 100 years, rising from 14°C to 15°C [8][9] - By the end of the century (2100), global warming may reach 1.5°C, with land areas and polar regions warming much faster [17] - Predictions for 2200 or 2300 show potential global warming of 8°C to 10°C, depending on emission control scenarios [17] Causes and Impacts - Increasing carbon dioxide (CO2) levels, measured in parts per million (ppm), are a primary driver of global warming [3][13] - Human activities, such as driving cars and operating factories, are responsible for the increase in CO2 emissions [4] - Serious effects of climate change include heat waves, floods, Arctic sea ice loss, and biodiversity loss, potentially leading to a sixth mass extinction [5] - The richest 10% of the global population release 27 tons of CO2 per person each year, while the bottom 90% release about 36 tons [19] International and Political Challenges - China is currently the largest polluter, but the United States was the number one polluter for the past 100 years until 2003 or 2004 [21] - International negotiations are crucial for controlling emissions, but political divisions, particularly in the United States, hinder progress [22][23] - The United States has a fluctuating commitment to the Paris Agreement, joining and withdrawing based on presidential administrations [25][26] Potential Solutions and Actions - Technical advances, policy actions, and individual actions offer hopeful signs for climate solutions [27] - Solar energy has grown by 42%, and the price of batteries has decreased significantly [27] - Reducing personal and family carbon footprints and electing climate-literate leaders are essential steps [28] - Public engagement, including protests and rallies, can make a significant difference [28][29]

Environmental Impact - Trees absorb carbon dioxide, which helps to reduce global warming [1] - The relationship between trees and global warming is complex and not always straightforward [1]
Could the sun be responsible for climate change? | Dr. Sami K. Solanki | TEDxHHN
TEDx Talks· 2025-08-14 14:41
Climate Change & Solar Activity - The world is warming, and while a small group initially attributed it to the sun, the scientific consensus now points to man-made greenhouse gases [1][2] - The sun's total energy output is immense, approximately 10^26 watts, originating from nuclear reactions in its core [5] - The Earth receives over 99.96% of its energy from the sun, influencing the planet's temperature and supporting life [8][11] - Solar activity varies, exhibiting an 11-year cycle with changes in X-ray brightness by a factor of 100 and fluctuations in sunspot numbers [13][14] - During the Maunder Minimum (approximately 1645 to 1715), a period of low sunspot activity, Europe and the North Atlantic region experienced a Little Ice Age [16] Research & Modeling - Solar brightness measurements from space over the past 40+ years show a small amplitude of 0.1% variation correlating with sunspot activity [18][19] - The SATIRE model was developed to estimate solar brightness during periods without direct measurements, such as the Maunder Minimum [21] - Carbon-14 production, influenced by cosmic rays and the sun's magnetic field, provides an indirect measure of solar activity over thousands of years [23][26] - Analysis of carbon-14 and climate data suggests a correlation between solar inactivity and cooler temperatures in the North Atlantic European region in prehistoric and historic times [29][30] Current Climate Change Drivers - Since approximately 1980, global temperature increases have diverged from solar activity patterns, indicating that man-made greenhouse gases are now the primary driver of climate change [34][35]
