Our opinion...

In our opinion, the global warming is a serious problem. The human beings we have to take care and respect our planet. Each of us have to help the planet. Only there is one planet! If the population we hope that the politicians arrange it ... we will die waiting.

Biofuels 'are not a magic bullet'

Biofuels may play a role in curbing climate change, says Britain's Royal Society, but may create environmental problems unless implemented with care.

In a new report, the Society suggests current EU and UK policies are not guaranteed to reduce emissions.
It advocates more research into all aspects of biofuel production and use.
The report says the British government should use financial incentives to ensure companies adopt cutting-edge and carbon-efficient technologies.
"Biofuels could play an important role in cutting greenhouse gas emissions from transport, both in Britain and globally," said Professor John Pickett from Rothamsted Research, who chaired the Royal Society's study.

"But it would be disastrous if biofuel production made further inroads into biological diversity and natural ecosystems.
"We must not create new environmental or social problems in our efforts to deal with climate change."

Climate 'could devastate crops'

Climate change could cause severe crop losses in South Asia and southern Africa over the next 20 years, a study in the journal Science says.

The findings suggest southern Africa could lose more than 30% of its main crop, maize, by 2030.
In South Asia losses of many regional staples, such as rice, millet and maize could top 10%, the report says.
The effects in these two regions could be catastrophic without effective measures to adapt to climate change.
The majority of the world's one billion poor depend on agriculture for their livelihoods. Yet, said lead author David Lobell, it is also "the human enterprise most vulnerable to climate change".
The researcher, from Stanford University in California, US, added: "Understanding where these climate threats will be greatest, for what crops and on what timescales, will be central to our efforts at fighting hunger and poverty over the coming decades."

EU set to agree emission cut plan

European leaders meeting in Brussels are set to endorse binding measures for cutting greenhouse gas emissions.

Slovenia's PM, who is chairing the summit, said the leaders had approved a timetable to implement an agreed 20% cut by 2020, compared with 1990 levels.
He likened the EU's plans to move to a low-carbon economy to a "third industrial revolution".
The summit is also discussing financial instability, as well as liberalisation of the bloc's energy markets.
Slovenian PM Janez Jansa said the leaders had taken note of a report by EU foreign policy chief Javier Solana warning of potential security concerns arising from global warming.
The report says climate change will have a growing impact on global security, multiplying existing threats such as shortages of food and water.
It warns that climate change could cause millions of people to migrate towards Europe as other parts of the world suffer environmental degradation.
Mr Solana's report "enjoyed a lot of support", Mr Jansa told reporters.
The EU leaders are considering specific targets put forward by the European Commission in January on how to achieve the agreed 20% cut in greenhouse emissions by 2020.
The BBC's Paul Kirby in Brussels says an important barometer for the success of the summit is how far the leaders are prepared to go in implementing those targets.
The liberalisation of energy markets is another contentious issue, our correspondent says.
Germany and France lead a group of countries hostile to calls for the break-up of big energy companies which run both power stations and the distribution networks.
European Commission President Jose Manuel Barroso said there was a general understanding that a European energy market was linked to having a secure supply and promoting renewable energy.
