El Niño has already arrived and this, added to the climate crisis, means that the world will experience new temperature records and weather extremes, with impacts on health (e.g. malaria outbreaks or extreme heat especially dangerous for farmers and outdoor workers), ecosystems (such as corals), infrastructure (energy grids at their limits), food security (collapse of crops affecting especially small farmers), conflict (episodes of intense heat are closely related to different types of violence), among others.
The globalised world is not prepared to cope with these temperatures and it is the most vulnerable people who suffer the most. We must cooperate to ensure immediate responses to the crises that arise, but also understand that drastic reductions in greenhouse gas emissions are urgently needed and that long-term, sustainable adaptation must be prepared that takes into account globalised and transboundary risks.
