IPCC calls for urgent climate action

The IPCC’s new Synthesis Report, released in March 2023, underscores the urgency of taking more ambitious action. IPCC says that “if we act now, we can still secure a liveable sustainable future for all”.

In 2018, the IPCC highlighted the unprecedented scale of the challenge required to keep warming to 1.5°C. Five years later, that challenge has become even greater due to the continued increase in greenhouse gas emissions.  The pace and scale of what has been done so far, and current plans, are insufficient to tackle climate change.

More than a century of burning fossil fuels, as well as the unequal and unsustainable use of energy and land, have led to global warming of 1.1°C above pre-industrial levels. This has resulted in more frequent and more intense extreme weather events that have caused increasingly harmful impacts on nature and people in every region of the world.

Every increment of warming results in rapidly escalating hazards. More intense heatwaves, heavier rainfall and other weather extremes further increase risks for human health and ecosystems. In every region, people are dying from extreme heat. Climate-driven food and water insecurity is expected to increase with increased warming. When the risks combine with other adverse events, such as pandemics or conflicts, they become even more difficult to manage.

Keeping warming to 1.5°C above pre-industrial levels requires deep, rapid and sustained reductions of greenhouse gas emissions in all sectors. Emissions should be decreasing by now and will need to be cut by almost half by 2030, if warming is to be limited to 1.5°C.

The forefront of cleaner, people-centred cities

Cities are dense and struggling with high levels of air pollution, sedentary behaviour and noise problems linked to car-centred urban planning. Traffic also takes up large areas in cities, resulting in lack of green spaces, and it is obvious that our oil dependency has fuelled climate change. Three cities with governments that are up for the challenge of re-thinking cities are Paris, Oslo and Barcelona, which are working to transform their cities from car-
centred to people-centred.
