India was ranked seventh among the list of countries most affected by climate change in 2019. [1] India emits about 3 gigatonnes (Gt) CO 2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. [2] The country emits 7% of global emissions, despite having 17% of the world population. [3]
Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [41] [42]
The data clearly shows a rising trend in global average surface temperatures (i.e. global warming) and this is due to emissions of greenhouse gases from human activities. The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple ...
Flowers of Beta vulgaris. Beta vulgaris is a herbaceous biennial or, rarely, perennial plant up to 120 cm (rarely 200 cm) height; cultivated forms are mostly biennial. The roots of cultivated forms are dark red, white, or yellow and moderately to strongly swollen and fleshy (subsp. vulgaris); they are brown, fibrous, sometimes swollen, and ...
The effect was more fully quantified by Svante Arrhenius in 1896, who made the first quantitative prediction of global warming due to a hypothetical doubling of atmospheric carbon dioxide. [20] The term greenhouse was first applied to this phenomenon by Nils Gustaf Ekholm in 1901. [13] [14
The state of Punjab led India's Green Revolution and earned the distinction of being the "breadbasket of India." [1] [2]The Green Revolution was a period that began in the 1960s during which agriculture in India was converted into a modern industrial system by the adoption of technology, such as the use of high yielding variety (HYV) seeds, mechanized farm tools, irrigation facilities ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [35] [36] [37] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [34]
In Asia, global warming of 1.5 °C (2.7 °F) will reduce the ice mass of Asia's high mountains by about 29–43%,: [56] Approximately 2.4 billion people live in the drainage basin of the Himalayan rivers: [57] In India alone, the river Ganges provides water for drinking and farming for more than 500 million people.
