U.N. Says Lag in Confronting Climate Woes Will Be Costly


Battery offers new hope to renewables

By Tim Radford - Climate News Network reposted from an original story

It sounds like a seminal step towards unlocking the potential of renewables - a research team has high hopes it has found a cheap and effective way of storing huge amounts of energy.

LONDON, 10 January - Scientists in the US think they may be on the track of a new kind of battery technology that could store huge reserves of energy.

One of the great problems of renewable energy generators such as photovoltaic cells and wind turbines is that they can’t respond to demand.

More species equals more ecosystem resilience

While still ostensibly ‘on leave’ (side note: Does any scientist really ever take a proper holiday? Perhaps a subject for a future blog post), I cannot resist the temptation to blog about our lab’s latest paper that just came online today. In particular, I am particularly proud of Dr Camille Mellin, lead author of the study and all-round kick-arse quantitative ecologist, who has outdone herself on this one.

Naomi Klein: climate movement needs radicals like Mandela

The fight against climate change needs to be as radical as the battle to bring down apartheid, says Canadian author and journalist in this original article from RTCC by Sophie Yeo published 11 December 2013.

The climate change movement needs to be as radical as Nelson Mandela’s fight against apartheid, said Naomi Klein, speaking to an audience in London today.

Gathering at the Royal Society for a conference on how global carbon emissions can be reduced drastically and immediately, speakers including Naomi Klein, Kevin Anderson and Corinne le Quéré argued for a new wave of radical environmental action.

Water supply will struggle to meet demands of thirstier world in a warming world

Irrigation CanalIrrigation CanalBy Jacob Schewe, Potsdam Institute for Climate Impact Research

There are already many countries where the scarcity of water affects people’s lives. While water for drinking may be first to come to mind, as agriculture is the largest use of water worldwide water scarcity first and foremost is a threat to food supply. And as many industrial processes rely on water availability, it also hampers economic development.

In the simplest sense, water scarcity is supply falling short of demand. Demand for freshwater will increase in most regions of the world due to population growth. Between eight and ten billion people are expected to live on Earth in 2050, as opposed to six billion today. But as for supply, water resources will be affected by projected climate changes due to unabated greenhouse gas emissions, for instance through changes in the amount, pattern and timing of rainfall and evaporation.

Global Carbon emissions continue to grow in 2013

Global carbon budget 2013Global carbon budget 2013By Tim Radford - Climate News Network - Original article. The world's emissions of the main greenhouse gas produced by human activities, carbon dioxide, in 2013 are expected to be nearly two-thirds higher than in 1990.

LONDON, 30 December - Global carbon dioxide emissions are likely to hit 36 billion tonnes in 2013, according to new research from the University of East Anglia in the UK. This is a small rise – an estimated 2.1% - on 2012, but it will be 61% above the levels in 1990, which is the baseline year for the Kyoto Protocol.

The Kyoto Protocol was agreed by most of the world’s concerned nations, anxious to reduce carbon dioxide emissions and contain warming to a global average of 2°C. So the 2013 carbon budget is not being hailed as a great success.

Drought will worsen some day somewhere

By Tim Radford - Climate News Network. An international research team says many more people will go short of water as the world warms. But who will be affected, and where, remains uncertain.

LONDON, 28 December - Droughts by the end of this century somewhere in the world will be 20% more frequent. But the catch is that nobody right now can predict with any certainty which places will feel the effects soonest, or more frequently.

Thirty research teams from 12 countries report in the Proceedings of the National Academy of Sciences that unless greenhouse gas emissions are reduced on a global scale, an extra 40% more people are likely to experience real water scarcity.
