Almost 200 countries on Saturday reached an agreement on implementing the Paris Climate Accord after two weeks of negotiations under the auspices of the United Nations.

The result of the tortured negotiations in the Polish city of Katowice is a 156-page rulebook on how countries will report and monitor their national pledges to curb greenhouse gas emissions and update their emissions plans.

What was agreed

The document covers a wide gamut of topics, but some key points of the deal include:

An agreement on how countries should report their greenhouse gas emissions and the efforts they're taking to reduce them.

An assurance of financial support for poor countries to help them cut emissions, adapt to inevitable climate changes, and pay for damages that have already happened.

Sticking points

Points where nations struggled to find common ground include:

How to create a functioning market in carbon credits, with countries such as Brazil wanting to keep carbon credits amassed under an old system. Agreement on the issue postponed for a future meeting.

Acceptance of the conclusions of the blockbuster IPCC report. Countries such as Saudi Arabia managed to water down wording to merely welcome the "timely completion" of the IPCC report, not its conclusions.

There was also a general lack of ambition in the final text to reduce emissions, with countries agreeing to consider the issue at a UN summit in New York next September.

'We're running out of time' on climate change Time is running out The protesters' symbol was a clock to signal to those meeting at the United Nations climate change conference (COP24) that time is running out if the world is to limit global warming to within 2 degrees Celsius (3.6 degrees Fahrenheit). Negotiations at the COP have been tough, with disagreements on financing for developing countries and on how states should report their emissions cuts.

'We're running out of time' on climate change Sending up Bolsonaro Some marchers made giant puppets, including of Brazil's president elect, Jair Messias Bolsonaro, to protest the leader's climate policies. Bolsonaro has threatened to follow US President Donald Trump and withdraw his country from the Paris climate agreement. Bolsonaro has also talked about loosening protections for the Amazon rainforest — the Earth's green lungs.

'We're running out of time' on climate change Air pollution woes About seven million people worldwide die prematurely due to air pollution every year. Poland's air quality is particularly bad because of the country's dependence on coal for electricity and heating. Some protesters decorated pollution masks to make a statement about Poland's coal policy. During the COP, the country's president said there was no intention to phase out coal.

'We're running out of time' on climate change 'Don't nuke the climate' Some groups, like the International Atomic Energy Agency, are promoting nuclear energy as an alternative to fossil fuels. It would provide a stable and greenhouse gas-emission-free energy source, says the IAEA. A number of protesters turned up to advocate against nuclear, because there is no good way to deal with the radioactive waste it produces and because it is potentially unsafe, they say.

'We're running out of time' on climate change A sustainable Christmas Sustaina Claus arrived at the climate march with his Christmas elves to preach the message of sustainability. The environmental activist says we need to stop overconsumption if we are to stop climate change and protect the planet's resources. Instead of buying mountains of gifts for your loved ones at Christmas, "you should give the gift of you."

'We're running out of time' on climate change Activists held at the border NGOs said a number of environmental campaigners were refused entry at the Polish border or deported from the country, having been deemed a "threat" to national security. Climate Action Network, an umbrella group of climate groups, called the actions worrying. A spokeswoman for Poland's border guards said she could not say whether the refusals were connected to the COP, according to Reuters.

'We're running out of time' on climate change Cycling for the climate Climate activist Lander Wantens cycled over 1,000 kilometers from Belgium to Katowice for the protest and to deliver a message to delegates to do more to combat climate change. He hopes that if the negotiators see "four guys from Belgium are crazy enough to bike to the climate summit in Poland in winter, maybe that's a signal that they have to work on an ambitious climate agreement."

Thousand steps forward

"It is not easy to find agreement on a deal so specific and technical. Through this package you have made a thousand little steps forward together. You can feel proud," Polish president of the talks Michal Kurtyka told delegates. "We will all have to give in order to gain," he said. "We will all have to be courageous to look into the future and make yet another step for the sake of humanity."

Climate change action groups said the agreement was a good start but it showed a lack of urgency among nations.

Executive director of Greenpeace Jennifer Morgan said: "We continue to witness an irresponsible divide between the vulnerable island states and impoverished countries pitted against those who would block climate action or who are immorally failing to act fast enough."

Alden Meyer of the Union of Concerned Scientists said: "While some rulebook elements still need to be fleshed out, it is a foundation for strengthening the Paris Agreement and could help facilitate US re-entry into the Paris Agreement by a future presidential administration."

How bad is the situation? The IPCC report that caused so much division at the negotiations found that to keep warming capped at 1.5 degrees there needs to be a dramatic overhaul of the global economy, including a shift away from fossil fuels. It warned that if the world warmed to even 2 degrees above pre-industrial levels, hundreds of millions of people would face dangerous climate-related risks by 2050, and 99 percent of the world's coral reefs would be wiped out. Greenhouse gas emissions need to drop by about 60 percent from current levels by 2030 to stay on a 1.5-degree path.
