Greenhouse gas (GHG) emissions in the European Union (EU) increased by 0.6 % in 2017, according to preliminary estimates from Member States, mostly because of road transport.

India, the world's largest groundwater user, withdraws about 230 billion m3 groundwater annually for irrigation.

Major oil and gas exporters have weathered many upheavals in recent decades but a renewed commitment to reform and economic diversification will be vital to cope with the changing dynamics of global energy.

The EU has agreed to cut its greenhouse gas (GHG) emissions by at least 80-95% by 2050. Climate policy will require a shift away from petroleum which currently provides nearly all of transport’s energy needs.

Sustainably feeding the next generation is often described as one of the most pressing “grand challenges” facing the 21st century. Generally, scholars propose addressing this problem by increasing agricultural production, investing in technology to boost yields, changing diets, or reducing food waste.

If individual cows that produce less methane could be bred with each other, it could bring down emissions, researchers say. Photograph: Alamy

Cutting down meat consumption and adopting a more "flexitarian" diet that includes more plant-based products could help combat some of the world's biggest problems including emission of green house

US President Donald Trump said he has yet to read a UN report warning of global warming-caused chaos unless drastic action is taken and added that he is sceptical.

Even as India has managed to increase its forest cover to over 20 per cent of its total geographical area, forest fires are a leading cause of degradation of the forest cover in the country says this new report released by the Ministry of Environment, Forests and Climate Change

Limiting global warming to 1.5 degrees would require rapid, far reaching and unprecedented changes in all aspects of society, the IPCC said in this new assessment. It compares the impact of global warming of 1.5 deg C and 2 deg C. It states that the world stands on the brink of failure when it comes to holding climate change to moderate levels and that there is only a decade to try and cut emissions.
