Analysts criticise fund – which focuses on cutting the impact of fossil fuels but will not support renewable energy - calling it a ‘drop in the ocean’

A $1bn fund to invest in cutting the climate change impact of fossil fuels has been announced by 10 of the world’s biggest oil companies, on the day the global Paris climate change agreement comes into force.

But analysts called the sum a “drop in the ocean” which showed the companies were not serious in tackling global warming.

Since 2010, Dr Thomas Krumpen from Germany’s Alfred Wegener Institute for Polar and Marine Research has been flying above northern Greenland towards North Pole to measure ice thickness. By lowering a small torpedo from the aircraft towards the sea ice scientists are able to to obtain data from inaccessible areas helping to build a clearer picture ice health

Environment groups hail ‘momentous occasion’ but warn governments need to cut carbon emissions more steeply to avoid dangerous global warming

The significance of the Paris agreement coming into force today is easy to miss: it may seem like an anti-climax, given the travails that led up to its signing last December.

But the moment is of huge importance. This is the first time that a legally-binding agreement, signed by all of the world’s functioning governments, has laid down a commitment to limit the growth of greenhouse gases in the atmosphere with the goal of preventing global warming exceeding 2C above pre-industrial levels.

Dyfi estuary, Wales A single egret, starkly white against the muted greys and browns of the saltings, flapped slowly up from the bed of a creek

From my vantage point on the southern side of the Dyfi estuary it was clear that my plan for the day had been compromised. The salt marsh, with its almost fractally complex pattern of creeks, pools and drains, is often host in late autumn to large groups of geese grazing contentedly within easy reach of the seawall.

On this visit those few geese visible through the pervasive anticyclonic murk were strung out along the seaward edge of the marsh, distant and difficult to approach. As if by compensation a single egret, starkly white against the muted greys and browns of the saltings, flapped slowly up from the bed of a creek just in front of me.

Deutsche Bank predict the state of South Australia could easily beat its aspirational target of 50 per cent renewables by 2025.

Environment groups hail ‘momentous occasion’ but warn governments need to cut carbon emissions more steeply to avoid dangerous global warming

The Paris agreement on climate change enters into force on Friday, marking the first time that governments have agreed legally binding limits to global temperature rises.

The passage of the accord – the fruit of more than two decades of often tortuous international negotiations on combating climate change – was hailed by nations and observers around the world.

For about $16,000, consumers can slash their grid bill to almost nothing and not worry about blackouts. The strategic and commercial implications are marvellous or frightening, depending on your vested interest.
