As the euphoria of delegates at the UN climate talks in Paris fades, BBC News proposes it is time to get down to the business of saving the planet and ask "what does it mean for me?"
Over the past two weeks, almost every nation on the planet has sent a team of negotiators to Paris to pore over page after page of nuanced jargon peppered with what seemed like a world record attempt for the most square brackets in a document.
But these brackets did matter. In the tense talks at a conference centre in north Paris, semantics was king.
Negotiators inhabited a world were "shall" would result in something becoming legally binding and "should" actually meant voluntary.
The fortnight kicked off with more than 150 world leaders, including Presidents Obama, Putin and Xi, descending on Paris to tell delegates that climate change was the most important issue facing us in the 21st Century.
Whether that was welcome support or unnecessary pressures it meant negotiators got down to business, often working through the night.
On Saturday evening - to claps, cheers and tears - a new landmark deal was born.
It was agreed by 195 nations. They will attempt to cut greenhouse gas emissions to a level that will limit the global average temperature to a rise "well below" 2C (3.6F) compared to pre-industrial levels - a level of warming deemed to be the point when dangerous climate change could threaten life on Earth.
What does it mean for me?
It depends on a multitude of factors - who you are, where you live, how you get from A to B, how you earn a living, how you spend your cash and how you like to spend your spare time.
If you live on a small low-lying island in the middle of the Pacific Ocean, the new agreement offers hope.
If nations manage to deliver then it could be the difference between having to flee your ancestral home and starting again thousands of miles away in an unfamiliar foreign land, or being able to plan and build for your family's future.
If you live in an industrialised, developed nation then it all depends on how committed governments and leading businesses are to achieving the goal. It could affect how much tax you pay, it could affect how much it will cost you to run a car - it may affect how much it costs you to feed and clothe you and your family.
But if nations do not commit to achieving the goal of limiting temperature rise to well below 2C, then the cost of adapting to the impact of a changing climate system will also affect the cost of living.
Numerous studies, including the Stern Review on the Economics of Climate Change, say the cost of inaction will cost us all a great deal more than shifting to a decarbonised, climate-friendly way of life.
If it's not legally binding, how will it work?
Some of it is legally binding within the United Nations framework. The regular review and submission of emission reduction targets will be binding.
So too will the $100 billion-fund from developed economies to help emerging and developing nations decarbonise their energy mix - which means moving away from burning fossil fuels to clean energy sources, such as renewables and nuclear.
What won't be legally binding will be the emission targets. These will be determined by nations themselves.
Within the agreement the targets are known as Intended National Determined Contributions (INDCs). To date, 187 countries have submitted their INDCs.
Observers have calculated that all of the targets, if delivered, will only curb warming by 2.7C. This is well above, not well below, the 2.0C goal of the Paris Agreement.
This begs the question why the targets themselves are not legally binding under international law.
This relates back to the 2009 climate summit in Copenhagen. Observers say the attempt to impose binding targets on countries then was one of the reasons why the talks failed.
In Paris, a number of big emitting emerging economies - including China, India and South Africa - were unwilling to sign up to a condition that they felt could hamper their economic growth and development.
