Question

In 2012, the UN conference of Parties on climate change was held at
(a)Warsaw
(b)Durban
(c)Doha
(d)Lima

Answer 1

Hint: There were 17,000 participants in the conference in 2012, held at the Qatar National Convention Centre and was the 18th session of the Conference of the Parties (COP), held annually. The main purpose of this conference was to extend the life of the Kyoto Protocol, which had been due to expire at the end of the year 2012, until the year 2020.

Complete answer:
The UN Conference of Parties on climate change was held at Doha, in the year 2012. The United Nations Climate Change Conferences are annual multilateral meetings of governments of countries worldwide. These conferences are held in different locations around the world under the sponsorship of the United Nations. The U.N serves as a forum for countries to discuss climate change matters. The conferences seek to address the threat of global warming caused by the release of greenhouse gases like carbon dioxide.
 These conferences are generally well covered by the world media. It was the largest conference to have ever been held in Qatar. The conference is sometimes called COP18 (Conference of the Parties ) but these are technically different and closely related conferences. The conference sometimes sees late night (or all night) working sessions when some diplomats cannot agree to the terms and conditions of agreements.
So, the correct answer is,’Doha.’

Note: Between the year 2000–2011 carbon dioxide growth in the atmosphere was 20% of the total concentration. The rise in Carbon dioxide concentration since the pre-industrial level in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012. While the pre-industrial concentration was 280 ppm. This is leading to climate change and to address such issues, these conferences are organized.
