Earth Greening Continues Over Last 35 Years
Earth greening continues from over last 35 years due to rising level of carbon dioxide. A quarter to half of the Earth’s vegetated lands has been continuously raising level of atmospheric Carbon Dioxide (CO2), a new study found.
According to photosynthesis, green leaves use energy from sunlight and combine with chemical CO2 drawn in from air with water and nutrients tapped from the ground to produce sugars. Which are the main source of food, fibre and fuel for life on Earth. Researcher added.
Other chemical for greening Earth
Not only carbon dioxide is the key that lead to increased plat growth but other chemical are also rotate the benefits, Nitrogen, land cover change and climate change by way of global temperature which precipitate with sunlight and change to greening effect.
Earth greening continues and over 85 percent of Earth’s ice- free land is covered by vegetation. These areas are mostly covered by all the green leaves on Earth which is very equal to 32 percent of Earth’s total surface area include oceans, lands and permanent ice sheets.
Carbon dioxide role in Earth greening
Carbon dioxide contribution has been most important element for this process in variable isolation through models that mimic the plant growth which was observed in the satellite data.
‘’More than 70 percent are effects by CO2 in Earth greening continues process in atmosphere. The second most important driver is Nitrogen with 9 percent contribution, Ranga Myneni Boston University, USA said.
The gas which traps heat in Earth has been increase due to Industrial age and burning of oil, coal, and wood for energy and its continuing to reach concentration not seen in at least 500, 00 years. The impact of climate change includes global warming, rising sea level, melting glaciers and sea ice as well as weather events.
Impacts of CO2 may also be limited as plant acclimatize, adjust to rising CO2 and the fertilization over time, Philippe Ciais of Climate and Environment Sciences in France, added.
