What Is Climate Change? How climate change raises the risk of glacier and rock collapse Climate change means abrupt shifts in temperature and weather. Some of these shifts occur naturally, while others result from human activities such as burning fossil fuels like coal, oil and gas. Burning fossil fuels produces greenhouse emissions that act like a blanket wrapped around the Earth, trapping the sun's heat and raising temperatures. The main greenhouse gases, such as carbon dioxide and methane, cause climate change. Clearing land and deforestation can also release CO2. Agriculture, oil and gas are the primary sources of methane emissions. These are a few of the main sources of greenhouse gases. We face a huge challenge, but we have many solutions. Climate change can be reduced by eliminating CO2 from the atmosphere, which requires systemic changes. The United Nations Environment Programme estimates that countries must double their pledges under the Paris Agreement within the next dec...
Maintaining Clean Indoor Air During Heatwaves: The Role of AC Filters Every summer seems hotter than the last, so cool indoor spaces are more important now. Home walls turn into shelters when the sun beats down without pause. Cool air flows more easily when machines run constantly, even though long afternoons. Still, most forget what hides inside those units humming in corners or ceilings. Hidden behind vents lies something small but vital: the filter trapping dust day by day. Breathing stays easy only if that piece gets attention every few weeks. Machines do heavy work yet rely on tiny parts doing theirs just right. Outside air grows heavier with pollutants when heat presses down hard. Dust rides the hot wind more easily under scorching skies. Pollen floats farther during long stretches without rain. Smoke lingers where temperatures climb high and stay. Inside, cooling systems push air nonstop through tight spaces. Filters strain each breath we take while machines hum all day. A...
