Inequality, marginalization and unsustainable use of land and ocean further expose the world’s population to human-induced climate change. According to a report by the UN’s Intergovernmental Panel on Climate (IPCC), released this Monday, 28, between 3.3 billion and 3.6 billion people are currently vulnerable to these effects – with different consequences between countries and regions, but markedly worse according to socio-environmental fragility.
In the Brazilian case, the document points out negative effects on agricultural production, with repercussions on the economy and food security, the greater exposure of the Amazon to the effects of climate change and human action and the danger that in the future large migratory masses in the Northeast will be caused by extreme events such as more frequent droughts and floods.
The latest IPCC document showed, in August 2021, that the Earth is heating up faster than predicted and is preparing to reach 1.5°C above pre-industrial level as early as the 2030s, ten years earlier than expected. . With this, there will be more frequent extreme weather events, such as floods and heat waves.
The estimated population today exposed to the effects of climate change represents up to more than 50% of the world’s population of 7.8 billion people. Even if the temperature temporarily exceeds 1.5ºC above pre-industrial levels, the expected impacts are severe and some even irreversible.
“Giving up leadership is criminal. The biggest global polluters are guilty of destroying our own home,” said UN Secretary-General António Guterres. “Denial and procrastination are not strategies, they are a recipe for disaster,” added the US government’s special climate envoy John Kerry.
most affected
Despite efforts to mitigate these effects, populations and ecosystems least able to cope with climate change have been hardest hit, says the document approved Sunday by 195 IPCC members. They are places marked by development patterns linked to colonialism and ineffective governance.
Central and South America are highly exposed, the report says. The region is vulnerable and strongly affected by global warming, a situation amplified by inequality, poverty, population growth and high population density in cities, with the occupation of risk areas.
In this context, the document says, some regions of Brazil are highly likely to suffer drastic consequences. In the Amazon, changes in land use and deforestation will make it more susceptible to extreme events and forest fires.
In Southeast Brazil, changes are expected in the pattern of rains and droughts that will impact the economic life of large urban agglomerations. In the Northeast, as well as the Andean region and northern Central America, the effects of climate change, such as droughts and floods, can cause the forced displacement of populations.
This year, in Brazil, for example, heavy rains, more concentrated and frequent, hit the states of Bahia, Minas, Goiás, Espírito Santo and Rio de Janeiro. More than 200 deaths were recorded in Petrópolis this month as a result of storms and landslides.
