Brexit Britain’s dash for growth will be a disaster for the environment | Owen Jones

MPs showed a Trumpian disregard for the planet by voting en masse for Heathrow expansion

Many of those MPs who marched through the lobbies to vote in favour of expanding Heathrow this week – Labour parliamentarians among them – will speak eloquently, if pushed, about the threat of climate change. Unfortunately their words have been rendered meaningless by their vote. You cannot truly fear the impact of climate change and then opt to raise aviation emissions by 7.3m tonnes of carbon dioxide – a figure that, as Greenpeace notes, is equivalent to the annual total output of Cyprus.

Wake up, Britain. We’ve been betrayed over Heathrow | Roger Hallam

MPs need to understand the whirlwind they will reap if they keep backing commercial interests over humanity’s survival

Some things are, to use Caroline Lucas’s word, “unforgivable”. The decision by MPs to put commercial interests ahead of the needs of our planet when it came to vote on the third runway at Heathrow represents a final, catastrophic betrayal. I had just finished a 14-day hunger strike, along with other Vote No Heathrow campaigners, to try to get across our objection to the idea. We are committed. Boris Johnson – supposedly an avowed critic of the plan – couldn’t even be bothered to turn up.

Trump should inspire us all, but not in the way you might guess | John Abraham

Joe Romm’s new book details the sticky messaging tactics successfully employed by Trump and others

Scientists like me – and really, everyone – can learn from President Donald Trump’s mastery of viral messaging.

True, he has turned the United States into a pariah nation, one reviled for ripping immigrant children from their parents and from withdrawing from our only real chance at stabilizing the climate, the Paris Accord.

I wrote this book because I have met so many frustrated scientists and environmentalists who want to get their message out, but don’t know how to be heard above the Niagara Falls of noise gushing from the internet and cable news. As an MIT-trained physicist who has been blogging for 12 years, I’ve learned a lot of the secrets of viral storytelling and messaging. But I’ve also had to unlearn a lot of things I was taught on the road to my Ph.D. So, I wrote this handbook for anyone who wants to learn the lessons from the world’s greatest viral communicators.

The main message is that if you want to grab and keep people’s attention – if you want to be as clicky and sticky as possible – you need to create an emotionally compelling and memorable message using a few basic rules. And rule number one is to tell a story with the simple And-But-Therefore formula used by Hollywood screenwriters and viral superstars like Oprah.

Climate change represents perhaps the greatest challenge we have ever faced as a civilization. But those seeking to communicate the scientific evidence have found themselves subject to concerted attacks by fossil fuel interests who find the implications of the science to be a threat to their bottom line.

Few have had both the courage to do battle with the forces of denial and the skill to communicate the science and its implications with clarity and vision. My friend Joe Romm is such an individual.

UK environment policies in tatters, warn green groups

‘Disastrous decisions’ such as Heathrow expansion and rejection of Swansea tidal lagoon spark concern over government direction

Environmental campaigners and clean air groups have warned that the government’s green credentials are in tatters after a flurry of “disastrous decisions” that they say will be condemned by future generations.

The government’s plan to expand Heathrow won overwhelming backing in the Commons on Monday – with more than 100 Labour MPs joining the majority of Tory politicians to back the plan – despite grave concerns about its impact on air pollution and the UK’s carbon emissions.

The environmental impact of a third runway at Heathrow | Letters

Letters from Dr Robin Russell-Jones, Les Bright and Andrew Papworth

This government’s decision to create more pollution at Heathrow (Report, 26 June) while simultaneously rejecting tidal power in Swansea Bay (Report, 26 June) shows it has no strategy for tackling climate change.

Although aviation only contributes about 2% of global emissions of carbon dioxide, it accounts for over 6% of global warming due the effects of other greenhouse gases and vapour trails. The upcoming report by the UK Committee on Climate Change shows that a third runway will increase CO2 emissions from air travel from 37 to 43 million tonnes per annum. But since our overall carbon budget will have fallen by 2030 to 344 million tonnes, the contribution from aviation will have jumped from 6.5% to 12.5% of the UK’s carbon emissions. In other words, a third runway is incompatible with the UK’s climate commitments, and things will only get worse post-Brexit.Dr Robin Russell-JonesMarlow, Buckinghamshire

Rising seas: 'Florida is about to be wiped off the map'

Sea level rises are not some distant threat; for many Americans they are very real. In an extract from her chilling new book, Rising, Elizabeth Rush details how the US coastline will be radically transformed in the coming years

In 1890, just over six thousand people lived in the damp lowlands of south Florida. Since then the wetlands that covered half the state have been largely drained, strip malls have replaced Seminole camps, and the population has increased a thousandfold. Over roughly the same amount of time the number of black college degree holders in the United States also increased a thousandfold, as did the speed at which we fly, the combined carbon emissions of the Middle East, and the entire population of Thailand.

About 60 of the region’s more than 6 million residents have gathered in the Cox Science Building at the University of Miami on a sunny Saturday morning in 2016 to hear Harold Wanless, or Hal, chair of the geology department, speak about sea level rise. “Only 7% of the heat being trapped by greenhouse gases is stored in the atmosphere,” Hal begins. “Do you know where the other 93% lives?”

Weatherwatch: California's clearer skies raise fire risk

Cloud cover is plummeting on the state’s south coast, leading to drier vegetation and greater threat of wildfire

The Golden State is in danger of becoming the “Cinder State”. New research reveals that cloud cover is plummeting in southern coastal California, increasing the chances of bigger and more intense wildfires.

Morrisons' paper bag switch is bad for global warming, say critics

Production and disposal of paper bags has greater climate impact than plastic, says Environment Agency

Experts have criticised Morrisons’ decision to switch from plastic to paper bags for fruit and vegetables, branding it a retrograde step for efforts to tackle climate change.

This week the supermarket ditched transparent plastic bags in favour of recyclable paper ones, in a move it said was prompted by customers’ worries over pollution. But the step is likely to have unintended consequences and trade one environmental challenge for another.

30 years later, deniers are still lying about Hansen’s amazing global warming prediction | Dana Nuccitelli

Koch paychecks seem to be strong motivators to lie

30 years ago, James Hansen testified to Congress about the dangers of human-caused climate change. In his testimony, Hansen showed the results of his 1988 study using a climate model to project future global warming under three possible scenarios, ranging from ‘business as usual’ heavy pollution in his Scenario A to ‘draconian emissions cuts’ in Scenario C, with a moderate Scenario B in between.

Changes in the human effects that influence Earth’s global energy imbalance (a.k.a. ‘anthropogenic radiative forcings’) have in reality been closest to Hansen’s Scenario B, but about 20–30% weaker thanks to the success of the Montreal Protocol in phasing out chlorofluorocarbons (CFCs). Hansen’s climate model projected that under Scenario B, global surface air temperatures would warm about 0.84°C between 1988 and 2017. But with a global energy imbalance 20–30% lower, it would have predicted a global surface warming closer to 0.6–0.7°C by this year.

Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16. Assessed by Mr. Hansen’s model, surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect.

Dumbest sentence in WSJ oped: "Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16." Translation: "Temperature has not increased if you omit the data showing it has increased."

And it isn’t just Mr. Hansen who got it wrong. Models devised by the United Nations Intergovernmental Panel on Climate Change have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago.

Why should people world-wide pay drastic costs to cut emissions when the global temperature is acting as if those cuts have already been made?
