French President Emmanuel Macron has said the record number of fires in the Amazon rainforest is an “international crisis” that needs to be on the top of the agenda at the G7 summit.
“Our house is burning,” he tweeted.
Brazilian President Jair Bolsonaro said his government was “open to dialogue” about the surge in fires.
But he said calls to discuss the issue at the G7 summit, which Brazil is not participating in, evoke “a misplaced colonialist mindset”.
Satellite data published by the National Institute for Space Research (Inpe) has shown an increase of 85% this year in fires across Brazil, most of them in the Amazon region.
Conservationists have blamed Mr Bolsonaro’s government for the Amazon’s plight, saying that he has encouraged loggers and farmers to clear the land.
He has suggested that non-governmental organisations started the fires, but admitted he had no evidence for this claim.
Mr Macron, host of this weekend’s G7 summit of some of the world’s most advanced economies, warned on Thursday that the health of the Amazon was a matter of international concern.
“The Amazon rain forest – the lungs which produce 20% of our planet’s oxygen – is on fire,” he tweeted. “Members of the G7 Summit, let’s discuss this emergency first order in two days!”
Mr Bolsonaro responded by accusing the French president of using a Brazilian domestic issue for “personal political gain”.
He said he was open to dialogue about the fires if it was “based on objective data and mutual respect”, but hit out at the calls for it to be discussed at the G7 summit.
“The French president’s suggestion that Amazonian issues be discussed at the G7 without the participation of the countries of the region evokes a misplaced colonialist mindset, which does not belong in the 21st century,” he wrote on social media.
He also accused Mr Macron of sensationalising the issue, including by using fake pictures.
The largest rainforest in the world, the Amazon is a vital carbon store that slows down the pace of global warming.
UN Secretary-General Antonio Guterres has also said he is “deeply concerned” about the fires there.
“In the midst of the global climate crisis, we cannot afford more damage to a major source of oxygen and biodiversity. The Amazon must be protected,” he tweeted.
How has Bolsonaro reacted to the fires?
Mr Bolsonaro has said that the country is not equipped to fight the fires. “The Amazon is bigger than Europe, how will you fight criminal fires in such an area?,” he asked reporters as he left the presidential residence on Thursday. “We do not have the resources for that.”
The president has suggested that NGOs may have started fires as revenge for his government slashing their funding.
Asked on Thursday who was responsible, he said: “The Indians, do you want me to blame the Indians? Do you want me to blame the Martians?… Everyone is a suspect, but the biggest suspects are NGOs.”
When asked if there was any proof of this, he replied: “Did I accuse NGOs directly? I just said I suspect them.”
Mr Bolsonaro has further angered those concerned over the spike in fires by brushing off the latest data.
He argued that it was the season of the “queimada”, when farmers burn land to clear it before planting. However, Inpe has noted that the number of fires is not in line with those normally reported during the dry season.
It is not the first time that Mr Bolsonaro has cast doubt on figures suggesting that the Amazon is deteriorating rapidly.
Last month, he accused Inpe’s director of lying about the scale of deforestation there. It came after Inpe published data showing an 88% increase in deforestation in the Amazon in June compared to the same month a year ago.
The director of the agency later announced that he was being sacked amid the row.
Why is he being criticised?
Climate activists and conservationists have been scathing about the Bolsonaro government and its policies, which favour development over conservation.
They say that since President Bolsonaro took office, the Amazon rainforest has suffered losses at an accelerated rate.
Their anger was further fuelled by satellite data showing a steep rise in fires in the Amazon region this year.
The figures suggest there have been more than 75,000 fires so far this year for the whole of Brazil, compared with just over 40,000 over the same period in 2018.
The figures and satellite images showing most of the state of Roraima, in northern Brazil, covered by smoke have shocked many Brazilians and triggered a global Twitter trend under the hashtag #prayforamazonia.
The US space agency, Nasa, has on the other hand said that overall fire activity in the Amazon basin is slightly below average this year.
As well as being a vital carbon store, the region is home to about three million species of plants and animals, and one million indigenous people.
Amazon fires cause stir on social media

The plight of the Amazon has seen millions take to social media to decry reports of a massive yearly increase in forest fires. But some of the most striking – and viral – pictures shared by social media users are not all they seem.
The hashtag #PrayForAmazonia started to be widely used on Tuesday. It has been included in almost three million tweets since.
The most widely shared tweet using that hashtag – with more than a million likes and retweets – includes two aerial images of forest fires, neither of which show the current situation.
One dates as far back as 1989. And other widely shared images include fires as far away as Siberia or the United States.
A video of a Pataxo woman angrily accusing illegal ranchers of starting fires has almost five million views. But the video has been shared on social media since at least July. So while it may point to one potential reason for the reported increase in forest fires, it’s not necessarily a depiction of the present situation.
What causes the fires?
Wildfires often occur in the dry season in Brazil but they are also deliberately started in efforts to illegally deforest land for cattle ranching.
“The dry season creates the favourable conditions for the use and spread of fire, but starting a fire is the work of humans, either deliberately or by accident,” Inpe researcher Alberto Setzer told Reuters news agency.
Ricardo Mello, head of the World Wide Fund for Nature (WWF) Amazon Programme, said the fires were “a consequence of the increase in deforestation seen in recent figures”.
