If the prime minister wishes to repair a reputation he once valued as an environmentally conscious moderniser and ensure he has a credible platform to speak from at this December's Paris Climate Summit he needs to use the next 100 days to prove the husky is alive and well.
Before polling day I was looking forward to a woman being secretary of state for energy and climate change after the election, but I hoped it would be me not Conservative Amber Rudd... To round it all off, we heard the ideological underpinning of many of these changes from the Secretary of State when she gave her first major speech on climate change last month. Divisive and short-sighted, it sought to dial down our distinctive leadership on climate change just as China, the US and much of the rest of the world makes bold moves, and instead sympathized with "the suspicion of those who see climate action as some sort of cover for anti-growth, anti-capitalist, proto-socialism"... As Amber and Andrea enjoy their holiday taking in some summer sun, beware. Winter is coming.
Last week, following months of painstaking negotiations that may have passed many readers by, UN negotiators in New York completed their work to finalise the text of 'Transforming Our World: The 2030 Agenda for Sustainable Development', setting out the final text of 17 Sustainable Development Goals.
Whenever David Cameron talks about the importance of climate action over the next few months, remember this is the guy who oversaw a government unnecessarily roll back much-needed policy. In politics, credibility is a difficult resource to reclaim once it's lost, as Cameron has learnt in Brussels. He may be about to learn that lesson again in Paris.
Here's a back-of-a-fag-packet precis of the list so far: Solar tariffs, slashed, onshore wind, shunned. Carbon neutral new-build homes, chucked. Financial help (grants and loans) for home insulation and micro-generation: forget it!
It's not often that one of the world's biggest polluters fills me with hope that we can tackle climate change. But yesterday President Obama showed leaders around the globe what climate action looks like, and his timing couldn't be better.
There is enough suitable previously developed land for at least a million new homes, much of it in London and the south east. If we make it easier to build in the Green Belt, these sites will be wasted and towns and cities will suffer. The Green Belt has been a huge success. Without it we would be immeasurably poorer. We should protect it, celebrate it, and go out and enjoy it.
As we look back on the first 100 days of this Government, many politicians, businesses and campaigners are also looking forward - with just four months to go until world leaders meet in Paris to agree a deal on climate change... Yet the first 100 days of Conservative rule have been grim for anyone who cares about securing a safe climate for our children and grandchildren.
As we approach the landmark of the first 100 days of his government, we at HuffPost UK have asked Britons to assess the state of the nation under the Conservatives. '100 Days of Dave' is a special blogs project looking at what's worked, what hasn't, and what more we can expect over the next five years of this Parliament. From grassroots campaigners to Government ministers, from critics to supporters, we aim to show a breadth of opinion as we take the national temperature on a range of policies including child poverty, mental health, the environment, housing and LGBT rights.
I harvest wild edibles for my own breakfast, lunch and supper table. A little here, a little there, and never more than a sixth of what's on offer. I ensure that plenty is left for the birds and bees. Common sense dictates that picking every summer elderflower in sight, doesn't bode well for elderberries in the autumn.
There's a lot of anti-hunting sentiment out there in the ether right now. I say hunting is fine, but let's just change up the rules a bit. If you want to kill a lion then go ahead - but no weapons, yeah? You've got to use your bare hands. Let's level the playing field - mano a animalo.
People today walk almost a third less than they did just twenty years ago. Whilst for our grandparent's generation, walking to school was the norm, nowadays it's becoming more and more uncommon.
We need to shed our naiveté and learn how to tell our stories so people will listen. I guarantee you won't get a celebrity-endorsed Twitter-storm about the destruction of seagrass and mangroves, but you might get it from the tale of Marvin the homeless manatee... We need to learn from this how to weave stories, to engage the public in the plight of wildlife. Conservation needs powerful friends, mass action and money, and icons and figureheads can be vitally important. If this tragic drama accomplishes any small part of this, then Cecil didn't die in vain.
The NGOs who signed the letter to the Prime Minister do not want to go to war with the Government. We welcome the Government's good intentions, not least its aspiration that ours should be "the first generation to leave the natural environment of England in a better state than that in which we found it". But things are going rapidly in the wrong direction.
We need to act to stop uncontrolled shark fishing now; adopting effective management before crisis recovery plans are needed. The high seas can no longer be an out of sight out of mind wild frontier where anything goes. We could lose sharks from our seas within my lifetime, and that simply must not happen. Lose the sharks, the mighty, mysterious lords of the deep, and our planet's oceans would be infinitely poorer places.
Come on, environmentalists. Don't hide behind the phrase 'green jobs'. If you want more renewables now, explain why you believe that environment trumps economics. If you believe that the UK should unilaterally lower our own carbon emissions immediately when the rest of the world isn't, and when our own action would be dwarfed by global trends, please tell us why. Make that case.
