In the run to every Christmas, big moments seem to come thick and fast.  This year is no different.  Here's a flavour of what to expect over the next couple of weeks...

...on Wednesday, the Chancellor delivers the results of the Comprehensive Spending Review.  We'll keep an eye out for the detail of Defra's settlement hoping that core capacity remains to deliver its major environmental commitments

...on Sunday, people will take to the streets in 57 cities around the world calling for action to tackle climate change.  Taking place on the eve of the crucial talks in Paris, the world's media will fall on the London event.  Understandably, the planned march in the French capital has been cancelled but everyone is keen to ensure the London march is the biggest ever.  It is a great an opportunity to send a clear message that we stand united with the people of Paris in support of a global climate change deal  My son and I will be walking with RSPB supporters.  I hope to see there as well.

...next Monday, the UN climate talks start and will continue until 11 December.  By then, we shall know how close collective commitment is to limit global temperature rises to 2 degrees above pre-industrial levels.  The Birdlife International contingent will focus on ensuring that adequate finance is in place to protect the world's tropical forests as part of the global deal.

...in two weeks time, environment ministers across Europe will meet in Brussels to reflect on the review of the EU Nature Directives.  After Friday's conference (more on this tomorrow), we can expect this to the moment that the UK declares its hand and show their support for the directives.  A smart outcome would be for ministers to express their desire to focus on enforcing and implementing the legislation.  If you have not already done so, you can still send a message (here) to our Minister, Rory Stewart, encouraging him to stand up for the laws that defend our nature. 

These are four big moments that will test our ability to act as stewards of this beautiful planet.  By Christmas, we'll know if we've done what nature needs or if the challenge has become even greater.
