People want to live in clean environment, but their wish has been confronted with a serious challenge: global warming.

According to statistics on the situation of damage from global warming published at the 20th general meeting of signatories to the UN convention on climate change held in Lima, Peru in December last year, extreme weather hit the world on 15 000 occasions in the past 20 years, leaving 530 000 people dead and causing losses worth several trillion dollars.

The UN inter-governmental committee on climate change, in a report published in 2013, predicted that global warming would result in a maximum 4.8ºC rise of temperature by the end of this century over the present one.

The World Bank argues that a 50cm rise of sea level by 2050 is an inevitable phenomenon.

To address the challenge of climate change the world has taken a big step forward towards drawing public attention to it and developing and implementing international convention on the basis of scientific analysis.

In July last year the 2014 annual meeting of the international forum on ecological civilization was held on the theme of “Reform and propel to make the world advance hand in hand to a new age of eco-civilization”.

As electric vehicles, called “low-carbon motors”, are in great demand, more countries are eager to invest in the field.

Germany published a national automobile development plan envisaging the production of a million electric motors by 2020 and the French government gives preferential loans worth hundreds of millions of euros to electric vehicle producers.

Portugal has made it a duty to build charging stations for electric vehicles in credit and public buildings newly constructed in the country.

Solar energy development technology has recently been recognized as the most promising power generation technology for the prevention of global warming.

Several countries have set the wide introduction of solar energy development technology as an important link of national energy strategy and are directing a great deal of efforts to it.

Solar panels have been fixed on the roofs of dwelling houses in cities and villages, and large-scale photovoltaic projects stepped up with increased investment in this sector in the EU. India, Russia and Norway are pushing ahead with the construction of windmills.

Projects have also been undertaken to prevent desertification of farmland.

Iran, Pakistan, Jordan and other Asian, African and Latin-American nations have set the creation of green walls as an important national policy and are stepping up tree planting and afforestation.

Now the UN works on a development plan for the prevention of global warming and sustainable development goals after 2015, and international debates are going on to address global warming.

The immediate task facing the UN is to hammer out a new climate convention to replace Kyoto Protocol, which expired in 2012, at the general meeting of signatories to the UN convention on climate change slated to be held in Paris in December this year.

Unlike Kyoto Protocol adopted in 1997, the new convention will involve developing nations in the reduction of greenhouse gas emission.

The DPRK, a member of the UN framework convention on climate change, also works hard to prevent global warming.

It takes an active part in the international efforts against global warming in close cooperation with international organizations.

Combat against global warming is not an undertaking for others.

It is a common task of all for themselves and the future of humankind.
