Record-breaking floods in Spain, violent storms in Florida and wildfires in South America - these are just a few examples of the extreme weather events accelerating and intensifying across the world. With the cost of inaction clearer than ever, financing for clean alternatives to the fossil fuels which are driving climate change will be top of the agenda at this year's UN climate conference, COP29 .
The context in which COP29 begins in Baku, Azerbaijan on November 11 is critical but not hopeless.
A UN climate report released just days before the Conference confirmed that global average temperature rise is approaching 1.5°C above pre-industrial levels, which would put the world on course for a catastrophic rise of 2.6-3.1°C this century, unless there are immediate and major cuts to greenhouse gas emissions.
A failure to act will lead to increasingly frequent and dangerous extreme weather events.
The UN is calling for urgent collective action, led by the G20 group of developed economies and the biggest emitters, to deliver the greenhouse gas emissions cuts needed to limit global warming.
What is the UN Climate Change Conference?
The climate crisis transcends borders. Solving it requires unprecedented international cooperation, with the UN and its chief, the Secretary-General, at the centre of the multilateral effort.
The annual UN Climate Change Conferences (otherwise known, in UN jargon, as COPs, or Conferences of the Parties to the UN Framework Convention on Climate Change), are the world's primary multilateral decision-making forum on climate change, bringing together almost every country on Earth.
They are unique opportunities for the world to come together to agree on how to address the climate crisis, limit the global temperature rise to 1.5 degrees Celsius, help vulnerable communities to adapt to the changing climate, and achieve net-zero emissions by 2050.
COPs are meant to be inclusive affairs and, as well as world leaders and government representatives, a diverse range of people from all aspects of society, from business leaders and climate scientists to Indigenous Peoples and youth, are involved, taking part in order to share insights and best practices to strengthen climate action that benefits all.
What is the focus of COP29?
A top priority for negotiators in Baku will be agreeing on a new climate finance goal, one that ensures every country has the means to take much stronger climate action, slash greenhouse gas emissions and build resilient communities.
The aim is for the conference to help unlock the trillions of dollars that developing countries need in order to mitigate harmful carbon emissions, adapt to climate change and cope with the loss and damage it has caused.
Look out for a continuation of discussions held at the UN Summit of the Future earlier this year on reforming the international financial architecture . The UN Secretary-General, António Guterres has described the current system as "entirely unfit for purpose" and ill-equipped to cope with today's challenges: many poor countries are facing unsustainable levels of debt that leave them unable to invest in social protection and health care, let alone measures that would bring about the transition to a low carbon economy.
What will happen over the two weeks?
As ever, there will be a packed schedule of negotiations, speeches, press conferences, events and panel discussions at the conference site, divided into a Green Zone - which is overseen by the COP29 Presidency and open to the general public - and a Blue Zone managed by the UN.
This is where the nitty-gritty of the negotiations will take place, as the representatives of the nations of the world try to thrash out a deal by the end of the event. An agreement is usually reached, but not without drama, with last minute disagreements pushing the talks beyond their official deadline.
Why are COPs important?
The importance of COPs lies in their convening power: the decisions made at each of them may not go as far as some may hope, in terms of addressing the climate crisis, but they are made by consensus, uniting the countries of the world in international agreements that set standards and advance action in critical areas.
In 2015, at COP21 in Paris, a landmark climate agreement was reached in which countries agreed to reduce global warming to well below 2 degrees Celsius above pre-industrial levels and pursue efforts to limit it to 1.5 degrees. The Paris Agreement works on a five- year cycle of increasingly ambitious climate action by countries. The next updated national climate action plans - known as Nationally Determined Contribution s, or NDCs - are due in 2025. This process has led to incremental but important improvements, in terms of reduced emissions and measures to promote the adoption of renewable energy sources.
Each year, negotiators build on progress made at the previous year's COP, strengthening aspirations and commitments, and pushing for new agreements, based on the latest scientific findings on the climate, and the role of human activity in the crisis.
What comes next?
Beyond the conference walls, there are many positive signs that the clean energy transition is gathering pace, and already paying huge dividends, in terms of the creation of jobs and boosting the economies that are embracing it.
Renewables are entering the energy system at an unprecedented rate, and electricity from new wind and solar power is now cheaper in most places than electricity from fossil fuels.
A future powered by renewable energy is now inevitable. Those who take decisive action and invest in clean technologies today are expected to reap the biggest rewards in the years to come.
Even before the end of COP29, delegates will be ironing out the details of their improved national climate plans, which amongst other targets will focus on transitioning away from fossil fuels, and keeping the world on track to a no more than 1.5 degree increase in global temperatures.
