Urgent action is needed to limit global temperatures and protect human and planetary health.

Climate change is a threat to human wellbeing and planetary health. Any further delay in concerted anticipatory global action on adaptation and mitigation will miss a brief and rapidly closing window of opportunity to secure a liveable and sustainable future for all.

Climate change has already caused widespread adverse impacts and losses and damages to nature and people, some of which are irreversible. About 3.5 billion people are living in conditions highly vulnerable to climate change, and across sectors and regions, it is the most vulnerable people and systems that are most at risk. The disproportionate balance of risk on the most vulnerable is linked to socio-economic factors, inequity, marginalisation, colonialism and governance.

As the various impacts of climate change across different systems such as heat stress, water scarcity, flood risk and food insecurity increase, so too does the complexity of managing multiple climate hazards happening simultaneously, which could significantly impact on many aspects of health and wellbeing. Some of the overlapping challenges include increased exposure to heatwaves and heat-related mortality, increased risk of food-, water- and vector-borne diseases, and increased mental health challenges, including anxiety and stress.

Adverse impacts and the related losses and damages increase with every increment of global warming. The scale of the challenge, both in terms of the magnitude and rate of change, is therefore strongly dependent on the mitigation and adaptation actions we take now and over the medium to longer term. This will require rapid, deep cuts in greenhouse gas emissions combined with widespread adaptation action.

Effective mitigation and adaptation strategies have the potential to deliver multiple benefits including reducing poverty, improving health and wellbeing, reducing inequality, and protecting natural life.

Governments, civil society, and the private sector need to work together to make inclusive choices that prioritise risk reduction, equity and justice that will:

  • Rapidly decarbonise the world economy
  • Support and protect vulnerable populations
  • Enhance biodiversity and regenerative agriculture
  • Help people, economies, and the environment adapt and prepare for the impacts of climate change
