Increase of carbon dioxide in atmosphere in last 30 years india
Answers
Explanation:
Lauri Myllyvirta is an energy and air pollution analyst covering air pollution and fossil-fuel trends globally. Sunil Dahiya is an analyst with Greenpeace East Asia who tracks India’s progress towards its pollution targets.
In the first eight months of 2019, growth in India’s CO2 emissions slowed down sharply, putting the country on track to its lowest annual increase in nearly 20 years.
Our analysis, based on data from various ministries responsible for electricity, coal, oil, gas and foreign trade, shows that emissions increased by 2% in the first eight months of the year, a lower rate than any annual increase since 2001.
The main reason was a slowdown in the expansion of coal-fired electricity generation, the analysis shows, with renewable output surging and demand growth slowing.
Oil demand growth has also slowed this year, helping keep the increase in India’s emissions to just 2%, against an average of 5% per year over the past decade.
The trend in India’s CO2 emissions is of global importance. Since 2013, the country has accounted for more than half of the increase in global CO2 output. Slower growth in coal-based power generation will also benefit the country’s air quality efforts, as essentially all coal-fired power plants in India lack pollution controls commonly required in, say, the EU and China.
Slowest growth
India’s CO2 emissions have doubled since 2005, driven by a rapid expansion in coal use. The growth is poised to slow down in 2019, however, as the chart below shows.
Electricity generation from coal slowed markedly in the first eight months of 2019, putting the country on track to its slowest power-sector emissions increase in three decades. This was due to a surge in renewable power generation and a slowdown in demand growth, which means the share of fossil fuels in meeting power demand growth will be the lowest in the past 30 years
As a result, India’s coal use (black area in the chart) increased relatively slowly in the first part of 2019. Oil demand growth moderated, too (blue), meaning CO2 emissions in the first eight months of the year increased by an estimated 2.0% (red line).
Answer:
Carbon dioxide concentrations are risingmostly because of the fossil fuels that people are burning for energy.The concentration of carbon dioxide in Earth'satmosphere is currently at nearly 412 parts per million (ppm) and rising. This represents a 47 percent increase since the beginning of the Industrial Age, when the concentration was near 280 ppm, and an 11 percent increasesince 2000, when it was near 370 ppm.Over the last 150 years, carbon dioxide (CO2) concentrations have risen from 280 to nearly 380 parts per million (ppm). The fact that this is due virtually entirely to human activities is so well established that one rarely sees it questioned.
