All the indicators of climate change are in red

Barack Obama warns climate change could create refugee crisis ‘unprecedented in human history’

Climate change could produce a refugee crisis that is “unprecedented in human history”, Barack Obama has warned as he stressed global warming was the most pressing issue of the age.
Speaking at an international food conference in Milan, the former US President said rising temperatures were already making it more difficult to grow crops and rising food prices were “leading to political instability”.

If world leaders put aside “parochial interests” and took action to reduce greenhouse gas emissions by enough to restrict the rise to one or two degrees Celsius, then humanity would probably be able to cope.
Failing to do this, Mr Obama warned, increased the risk of “catastrophic” effects in the future, “not only real threats to food security, but also increases in conflict as a consequence of scarcity and greater refugee and migration patterns”.

Itis a must to tackle climate change that causes hunger in East Africa

Oxfam is now warning the drought in East Africa, where nearly 11 million people are already affected by food shortages, is threatening to become a humanitarian “catastrophe”.
Issuing a “desperate” appeal for the international community to meet a request from the United Nations for about £1.5bn of aid, the charity also said the worst drought in living memory demonstrated why the world must act to reduce global warming.
It pointed to several scientific studies which found evidence that climate change was likely driving up temperatures and making the situation significantly worse.
“Nearly 11 million people in Kenya, Ethiopia and Somalia are dangerously hungry and in need of humanitarian assistance,” Oxfam said in a briefing.
“There is mounting evidence that climate change is likely to be contributing to higher temperatures in the region, and that increased temperatures are exacerbating the impacts of drought,” Oxfam said.
“Temperatures have been consistently higher in East Africa in recent years, part of a trend seen in Africa and around the world.
“Higher temperatures result in greater evaporation, meaning soil moisture is reduced, reinforcing drier conditions and intensifying the impacts of failed rains. Crops and pasture have less water, and the chance of failed harvests or lack of feed for livestock increases.
“In pastoral regions like northern Somalia, higher temperatures over the past six months have turned very low rainfall last year into a terrible loss of soil moisture – helping to desiccate all the available fodder for many of Somalia’s pastoralists.”

The clever practice of communications of climate-change sceptics overshadows the true advice of experts

Ministers should still weigh the importance of scientific evidence but “where they do not follow the results they must ensure that they do not dismiss or discredit legitimate scientific evidence”, a report of  the British Commons’ Science and Technology Committee said. It called for a “robust redress mechanism” – possibly including fines – in cases where science is misreported by the media.
In an age of claim and counter-claim about ‘fake news’, spin and misinformation about science risked causing real harm, warned Stephen Metcalfe MP, who chairs the committee.
“Robust consideration of scientific evidence is crucial to policy making and really affects our daily lives and we have seen over many years through the debates around BSE [‘mad cow disease’], climate change, [vaccine] MMR and new medical treatments,” he said.
“However too often the clever practice of communications overshadows the true advice of experts, and the public are left bewildered, and not knowing who to believe.
“This affects Government policy too, Ministers and decision makers must take greater care to set out exactly how scientific evidence is being considered, and ensure they cannot be accused of discrediting or skewing the evidence for financial reasons or to suit political aims.
“Reporting scientific and particularly health issues accurately is also a big responsibility for media organisations if they are to retain public trust, and we need to give the public greater reassurances that they are being properly informed and engaged.”
