From Mexicans left homeless by rising seas to Colombians affected by coral bleaching, hundreds of people are telling the top human rights court in the Americas what climate change means to them in a historic case that could shape international law.
Environmental lawyers also hope the hearings at the Inter-American Court of Human Rights (IACHR), which were requested by Colombia and Chile, will define the duties of states to confront the climate crisis and stop it infringing on human rights.
As well as receiving submissions from climate victims, the Costa Rica-based court, which started its inquiry in Barbados in April, will hear from UN agencies, legal experts, grassroots environmental campaign groups and youth groups.
The next sessions are due to be held in Brasília and then Manaus, Brazil at the end of May, and an advisory opinion is expected by May 2025.
“We're hoping that the court's legal opinion is a guide and reference for Mexico, and other states, to develop public policies from a climate justice perspective,” said Nora Cabrera, a lawyer and head of Our Future, a Mexico-based youth climate justice campaign group.
“And that it includes loss and damage compensation for affected communities, and adaptation policies for those not yet directly affected by climate change,” said Cabrera, who will be speaking at the next hearing in Manaus.
In January, Colombia and Chile asked the IACHR to issue the advisory opinion, saying that they were experiencing the “daily challenge of dealing with the consequences of the climate emergency,” including fires, landslides, droughts and floods.
“These events reveal the need for an urgent response based on the principles of equity, justice, co-operation and sustainability, with a human rights-based approach,” they said in their petition.
“There is a close relationship between the climate emergency and the violation of human rights,” they added.
It is this link between climate change and human rights that the IACHR will seek to define, while also examining how climate change affects migration and looking at the disproportionate effect on children, women and Indigenous people.
Chile and Colombia also asked the court for clarification on a state's duties to protect environmental activists.
Latin America is the most dangerous place in the world for environmental and land defenders, according to advocacy group Global Witness. About90 per cent of the 177 killings of environmental activists recorded in 2022 took place in the region.
“The hearing aims to ask for clarity about human rights obligations and the climate crisis,” said Jacob Kopas, senior attorney at the Earthjustice environmental group, one of a group of lawyers who spoke at the Barbados hearing on April 26th.
“It will help to create a more concise framework to guide state behaviour and policy to confront the climate crisis and protect human rights,” said Kopas.
Among those submitting testimonies will be the residents of the El Bosque fishing community in Tabasco, Mexico, where rising sea levels caused by climate change have swept away about 200 meters of coastline.
Since 2019, the school and more than 50 homes have been destroyed, forcing about 200 people to leave.
El Bosque community leader, Guadalupe Cobos, said she and 10 neighbours will probably have to leave within a year and resettle in an area about 12km away, where new homes are being built by the government.
“We depend on the sea but coastal erosion has affected our way of life. It's important for the court to know that we're living climate change now and that this isn't something that will happen in the future in 20 or 50 years' time,” said Cobos.
“We want the court to hear our experiences and to know that our rights have been violated, that we have been forced to migrate,” Cobos told the Thomson Reuters Foundation.
The court's advisory opinion could have important implications for climate litigation across Latin America and the Caribbean and make it easier for communities living with the effects of global warming to take legal action.
The opinion will apply to all signatories of the American Convention on Human Rights, most of whom are members of the Organization of American States. The United States and Canada have not ratified the treaty however.
The advisory opinion will help shape the region's legal systems as many countries incorporate its jurisprudence into their laws and constitutions.
“We're hoping that the court makes the link between the climate crisis and human rights violations and that it recognises climate displacement,” said Cabrera, whose organisation has been supporting the El Bosque community.
The IACHR is known for its progressive stance on climate justice and human rights.
In March, it recognised that citizens in Peru have the right to a healthy environment when it ruled in favour of people living in the Andean mining town of La Oroya, who had suffered from decades of environmental pollution.
Other courts are also breaking new ground in this sphere.
In Colombia in April, in response to a lawsuit filed by a farming couple who were driven out of their home by flooding caused by heavy rains, the country's constitutional court recognised the links between environmental disasters and climate change and people being forcibly displaced.
Across the world, other top courts are also examining the connection between human rights and climate change. On April 9th, the European Court of Human Rights (ECHR) ruled that the Swiss government had violated the human rights of its citizens by failing to do enough to combat climate change.
Two other courts – the International Court of Justice and the International Tribunal for the Law of the Seas – are also expected to give advisory opinions on international legal obligations of states regarding climate change.
Kopas said the IACHR ruling could lead the way by delivering a “forward-reaching and progressive” advisory opinion.
