ZOOM on the IPCC report

What is the IPCC?

The Intergovernmental Panel on Climate Change (IPCC) was created in 1988 to provide detailed assessments of the state of scientific, technical and socio-economic knowledge on climate change, its causes, potential impacts and coping strategies.

This association of nations represents, through individuals, member countries that will carry out assessments and syntheses of research conducted worldwide on climate change. The IPCC does not make recommendations, but projections. The transparency of the IPCC is total and all sources can be found on the IPCC website.

There are 3 main working groups and a Task Force (support group), which form the following main stages:

1ST PART August 2021

Addresses the physical understanding of the climate system and climate change.

2ND PART February 2022

Addresses the impacts, adaptation and vulnerability of human societies and ecosystems to climate change

PART 3 April 2022

Addresses global solutions to mitigate climate change and its effects.

SYNTHESIS September 2022

Summary of the report

The current state of the climate

  • There is no longer any doubt: humans are warming the atmosphere, the oceans and the land. These changes are widespread and rapid.
  • The magnitude of current climate change has not been observed for centuries, if not thousands of years.
  • There is much stronger evidence of human (so-called anthropogenic) responsibility for heat waves, torrential rains, droughts, and tropical storms.

Possible climate futures

  • Temperatures will continue to warm until at least 2050, but we can still avoid 2°C or even 1.5°C of warming compared to the pre-industrial era if we sharply reduce greenhouse gas emissions very quickly.
  • As the world warms, there will be an increase in the frequency and intensity of extreme heat events on land and in the oceans, heavy rainfall, drought in some regions, tropical storms, and a decrease in Arctic sea ice, snow cover and permafrost.
  • Globally, the monsoons will experience greater extremes between wet and dry.
  • If CO2 emissions continue to rise, the oceans and land will be increasingly unable to absorb it.
  • Some impacts will be irreversible for thousands of years, such as melting ice caps and rising sea levels.

Climate information for regional risk assessment and adaptation

  • Natural climate events such as El Niño and La Niña will continue to have some impact on some small-scale regions, but overall will have little impact on the long-term trend of global warming.
  • Compared to a +1.5°C warming, the impacts will be greater with a 2°C warming. In other words, every fraction of a degree we can avoid counts.
  • Even if the collapse of ice caps and ocean circulation is unlikely by 2100, we should not ignore this possibility.

Limiting future climate change

  • To stop global warming, we must at least achieve CO2 neutrality and sharply reduce emissions of other greenhouse gases.
  • A rapid and abrupt reduction in greenhouse gases can quickly lead to a more stable climate and improved air quality.

The Facts

In 2021, the average temperature increase is +1.09°C compared to the pre-industrial era.

The Paris agreements aim to limit the temperature rise to 1.5°C.

Taking into account the current commitments of the States, the warming would reach +2.7°C at the end of the century.

The impacts

Between 3.3 and 3.6 billion
people live in situations that are highly vulnerable to climate change (especially in developing countries).

1 billion
people in coastal regions will be at risk by 2050.



Effective protection of 30-50% of ecosystems will help us adapt to the effects of climate change.


Through the implementation of green buildings and sustainable modes of transportation, among others.


The climate crisis is accompanied by other challenges such as increasing urbanization, social inequalities, etc.
