Causes, Effects And Solutions to Global Warming Essay the effects caused by the greenhouse gases water vapour, co2, methane, ozone, nitrous oxide, hydro fluorocarbons, sulphur hexafluoride, per fluorocarbons, chlorofluorocarbons, etc are called as the green house effect. But marked a turning point.
During a brutal summer heat wave, the summit cross on the 3,meter Grossvenediger threatened to topple over. Relentless heat thawed the permafrost that had held the giant marker steady for decades. By the end of that summer there were few, if any, doubters remaining. Even the most grizzled old-timers started acknowledging that a steady build-up of greenhouse gas pollution was visibly reshaping their world within the span of a human life.
Effects of global warming - Wikipedia
Forests are moving uphill, glaciers are vanishing, and plants are blooming several weeks earlier than just 30 years ago. Mountain temperatures are increasing more quickly than the global average, at a rate closer to that of the Arctic , and climate researchers are trying to figure out why. They suspect that the accelerated mountain warming is due to an effect documented in the Arctic—loss of albedo. The peaks are losing their shiny white blanket of snow and ice that reflects the sun's radiation back to space. Instead, darker-colored ground absorbs heat, amplifying the heat-trapping effect of greenhouse gas pollution.
Effects of Global Warming on the Environment Essay
But there's not quite enough data yet to prove the conventional wisdom of rapid mountain warming, says University of Portsmouth geographer Nick Pepin, who led a study that tried to assess climate change impacts to mountains on a global scale. Are they really warming as fast as we think? Temperature readings taken between 1, and 3, meters confirm the trend, but data is sparse from higher elevations.
There are very few ground-based weather stations above 3, meters and none above 5, meters, Pepin says, advocating for an expansion of mountain climate research. Satellite data can be used to measure land-surface temperature, and it shows that higher elevations are warming more than areas lower down, but the satellites aren't as accurate as ground-based readings. Direct observations are needed to validate the satellite data, Pepin says. Without better information, people risk substantially underestimating the severity of many already-looming problems, including a proliferation of damaging landslides, water shortages in densely populated lowlands—especially in Asia—and the extinction of some mountain plants and animals.

Pepin's recent study zoomed in on the Tibetan Plateau, which holds so much snow and ice that it's sometimes called the Third Pole. Temperatures in the region have climbed steadily. Above 4, meters in elevation, the rate of warming has increased by an astounding 75 percent in just the past 20 years, compared to areas below 2, meters. These rivers provide water to more than 1.
The melting glaciers foreshadow a major water supply crisis, and there's also a more immediate danger; destabilized ice masses threaten mountain communities with avalanches, landslides, and floods. Overall, about half the world's population depends on mountains for drinking water supplies, irrigation, mining, hydropower, agriculture, and recreation—including many people who live far away from mountains and never stop to think how their fate is tied to what happens on those high summits.
A recent study published in the journal Earth's Future tries to quantify some of the impacts on a global scale. The findings suggest that communities around the world need to prepare for a future with less water. Sunrise alpenglow on the face of the Gore Range in Summit County, Colorado, where communities depend on winter snow to fuel their recreation economy, while nearby Denver waits for the snow to melt to fill reservoirs.
Breaking the effects on water resources down by region, the scientists found that the volume of glacier ice will decline by 80 percent or more in the South American Andes and the European Alps, and by 60 percent or more in western Canada, Scandinavia, the Caucasus, and Southeast Asia. In the densely populated European Alps, climate records go back more than years and the decline of alpine glaciers is documented in painstaking detail.
