Andrew Neil - these are your climate errors on BBC Sunday Politics | Dana Nuccitelli
On last week's BBC show Sunday Politics, Andrew Neil hosted UK Energy and Climate Change Secretary Ed Davey for a discussion about climate science and policy. Neil subsequently requested that people provide him with examples of the factual errors in this interview. Given that he began the show with several errors about the paper I co-authored finding a 97 percent consensus in the peer-reviewed literature that humans are causing global warming (the inspiration for the name of our blog), I would be happy to oblige.

Oh dear. Older people are more likely to have better knowledge of trees. 23% of those aged 55 and over can recognise an ash leaf, compared with 10% of 18-24s, and 68% of people older than 55 can recognise an oak leaf, compared with 39% of 18-24s, according to the Wildlife Trust

Last month, it was revealed that levels of a toxic pesticide more than 100 times the EU limit were present in a source of English drinking water. The discovery of record levels of metaldehyde – a chemical used in slug pesticides – was reported by Natural England and the Environment Agency at the River Stour, which supplies water to homes in Essex and Suffolk. There's currently no treatment method available to extract this chemical from drinking water – once it's there, we're drinking it.
This isn't a sudden unexpected situation. The same problem occurred in many areas across Britain last autumn – when slug numbers exploded after the wet spring and summer, conditions that we're seeing emerge again. The problem was identified in autumn 2007, when new analytical techniques allowed testing for metaldehyde, and since then a voluntary stewardship programme with guidelines for the use of the chemical has been instituted. Yet this clearly isn't working.

The two main advocates of a European renewable energy revolution driven by a vast grid of desert solar power have split, each accusing the other of poor communication.
Both the Desertec Foundation and the Desertec Industrial Initiative (Dii) say their plans to generate power from deserts across the world remains uncompromised despite the decision, which was made by the Foundation at an extraordinary board meeting last week.

Whales flee from the loud military sonar used by navies to hunt submarines, new research has proven for the first time. The studies provide a missing link in the puzzle that has connected naval exercises around the world to unusual mass strandings of whales and dolphins.
Beaked whales, the most common casualty of the strandings, were shown to be highly sensitive to sonar. But the research also revealed unexpectedly that blue whales, the largest animals on Earth and whose population has plummeted by 95% in the last century, also abandoned feeding and swam rapidly away from sonar noise.

Humans – the real threat to life on Earth
Earth is home to millions of species. Just one dominates it. Us. Our cleverness, our inventiveness and our activities have modified almost every part of our planet. In fact, we are having a profound impact on it. Indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. And every one of these problems is accelerating as we continue to grow towards a global population of 10 billion. In fact, I believe we can rightly call the situation we're in right now an emergency – an unprecedented planetary emergency.
We humans emerged as a species about 200,000 years ago. In geological time, that is really incredibly recent. Just 10,000 years ago, there were one million of us. By 1800, just over 200 years ago, there were 1 billion of us. By 1960, 50 years ago, there were 3 billion of us. There are now over 7 billion of us. By 2050, your children, or your children's children, will be living on a planet with at least 9 billion other people. Some time towards the end of this century, there will be at least 10 billion of us. Possibly more.

Today marks the 160th anniversary of a seminal, but largely forgotten moment in the history of the conservation movement.
On Monday, 27 June, 1853, a giant sequoia – one of the natural world's most awe-inspiring sights - was brought to the ground by a band of gold-rush speculators in Calaveras county, California. It had taken the men three weeks to cut through the base of the 300ft-tall, 1,244-year-old tree, but finally it fell to the forest floor.

Local, self-sufficient, optimistic: are Transition Towns the way forward?
Late last year, Rob Hopkins went to a conference. Most of the delegates were chief executive officers at local authorities, but it was not a public event. Speaking in confidence, three-quarters of these officials admitted that – despite what they say publicly – they could not foresee a return to growth in the near future.
"One said: 'If we ever get out of this recession, nothing will be as it was in the past,'" Hopkins recalls. "Another said: 'Every generation has had things better than its parents. Not any more.' But the one that stunned me said: 'No civilisation has lasted for ever. There is a very real chance of collapse.'"

Fishing is expected to be banned near the Atlantic islet of Rockall after a rare methane gas vent in the seabed and two new shellfish species were discovered by British scientists.
The methane, which leaks through a so-called "cold seep" vent in the ocean floor, was found last year by scientists working with the government agency Marine Scotland. It is the first of its kind to be found near UK waters and only the third in the north-east Atlantic.

The RSPB has admitted killing hundreds of birds on its reserves, prompting an accusation of "extraordinary hypocrisy" from the Countryside Alliance.
The RSPB recently criticised the licenced destruction of buzzard eggs and nests to protect a pheasant shoot and said a cull of lesser black-backed gulls should be halted. But on Thursday the charity revealed it too had destroyed lesser black backed gulls and other birds that were harming native species.

'Badger-friendly' milk to be sold in just three UK supermarkets
Only three UK supermarkets – Waitrose, Marks & Spencer and Asda – can guarantee they will sell milk that does not come from dairy farms inside zones where badger culls are due to take place, according to a survey by campaigners.
The survey also revealed that milk certified as organic will not be guaranteed as coming from farms outside the cull zones in Somerset and Gloucestershire.

Scientists across the Mediterranean say a surge in the number of jellyfish this year threatens not just the biodiversity of one of the world's most overfished seas but also the health of tens of thousands of summer tourists.
"I flew along a 300km stretch of coastline on 21 April and saw millions of jellyfish," said Professor Stefano Piraino of Salento University in southern Italy. Piraino is the head of a Mediterranean-wide project to track the rise in the number of jellyfish as global warming and overfishing clear the way for them to prosper.

They are adorably cute, with grubby brown fur so soft it seems to slip through my fingers like flour. It is only when one of the nine-week-old cubs playfully grabs my arm with its teeth and squeezes with an agonising grip that I remember – this is a lion, a wild animal. These four cubs are not wild, however. They are kept in a small pen behind the Lion's Den, a pub on a ranch in desolate countryside 75 miles south of Johannesburg. Tourists stop to pet them but most visitors do not venture over the hill, where the ranch has pens holding nearly 50 juvenile and fully-grown lions, and two tigers.
