Climate change caused the devastating floods of 2020 in Minas Gerais, Brazil, study concludes

Torrential rain resulted in losses estimated at BRL 1.3 billion and made over 90,000 people homeless in the state, where the probability of far higher volumes of rain than expected has increased 70% owing to industrialization and global warming.

Climate change will alter functioning of marine microbial communities, study shows

Plankton are the foundation of life in the oceans and produce half the world’s oxygen. These marine microorganisms will suffer from rising temperatures at the poles, rising salinity in the tropics, and a reduction in the flow of nutrients in the temperate zone, according to simulations based on data collected from all oceans around the globe.

Large infrastructure projects in the Amazon have bequeathed a harmful social and environmental legacy

For scientists gathered at this FAPESP-hosted webinar, projects like the Belo Monte dam and the Transamazon highway have had few local benefits and led to a rise in poverty, violence, deforestation and disease.

Electoral cycles influence destruction of Atlantic Rainforest areas in South and Southeast Brazil

Study led by researchers at the University of São Paulo analyzed data for the period 1991-2014 and revealed that deforestation increased in election years. The phenomenon could cancel out the environmental gains achieved by conservation policies and actions, the scientists warn.

Scientists use radar data to measure the impact of forest fires in the Amazon

The researchers combined VOD, an indicator of the amount of water in vegetation, with remote sensing data from optical satellites. The innovative strategy described in Remote Sensing provides a more comprehensive understanding of the biomass changes caused by fire.


Fire in wet area of the Amazon destroys 27% of trees in up to three years, study finds
SDG 13
Fire in wet area of the Amazon destroys 27% of trees in up to three years, study finds

Based on data collected in the field, Brazilian researchers showed that small and medium trees suffer most in the first two years after a fire, but the overall impact on vegetation can last decades. Carbon stocks fall 12.8% in burned areas on average.


Without proper management, wildfires in natural areas will intensify in the months ahead, study warns
SDG 13
Without proper management, wildfires in natural areas will intensify in the months ahead, study warns

A study alerts to the conjunction between a climate change scenario and little inspection with the arrival of the dry season in the country, which favors large-scale fires – such as that which occurred in the Pantanal in 2020. To avoid further tragedies, researchers defend the implementation of a policy of integrated fire management.

Nature-based solutions are essential to combat the adverse effects of climate change

Researchers analyzed strategies for ecosystem conservation and rehabilitation of degraded areas in the second part of the FAPESP 60 Years Lectures.


States and cities have potential to advance climate change mitigation
SDG 13
States and cities have potential to advance climate change mitigation

Action to reduce greenhouse gas emissions by subnational governments could help countries achieve their climate targets and contribute to the post-pandemic economic recovery, experts suggested at an event hosted by FAPESP.


Droughts may increase in South America by the end of the century, study suggests
SDG 13
Droughts may increase in South America by the end of the century, study suggests

If greenhouse gas emissions continue at the current level, the average temperature will tend to rise by as much as 4 °C in some regions. Under this scenario, extreme weather events will be more intense and frequent, according to projections made using the IPCC’s new climate models.


Impact of rising levels of CO2 in the Amazon could outdo that of deforestation in reducing rainfall
SDG 13
Impact of rising levels of CO2 in the Amazon could outdo that of deforestation in reducing rainfall

Simulations run by Brazilian scientists on a supercomputer at the National Space Research Institute (INPE) show that the direct impact of rising levels of carbon dioxide over the Amazon rainforest would be a reduction in rainfall equivalent to or even greater than the impact of complete substitution of the forest by pasture. The result calls attention to the need for regional and global action to mitigate the adverse effects of climate change.

Researchers highlight inconsistencies of Brazilian policy to deal with climate crisis

In the run-up to the 26th UN Climate Change Conference of the Parties (COP26), experts participating in a webinar hosted by FAPESP showed that the 2020 revision of Brazil’s nationally determined contribution failed to improve targets and allows in practice for a higher level of greenhouse gas emissions.


Marine sediments explain how part of Brazil’s Northeast region became semi-arid

Marine sediments explain how part of Brazil’s Northeast region became semi-arid

The phenomenon is linked to gradual contraction of the tropical rain belt over the last 5,000 years, according to a study conducted at the University of São Paulo. Its findings can help predict the region’s future climate.


Experiments simulate possible impact of climate change on crabs

Experiments simulate possible impact of climate change on crabs

Fewer Atlantic mangrove fiddler crab embryos survived in a warmer, more acid environment mimicking conditions forecast for the end of this century. Given the important ecological role of this invertebrate in mangroves, the researchers warn of a potential cascade effect.


Most cities in São Paulo state have low potential capacity to adapt to climate change

Most cities in São Paulo state have low potential capacity to adapt to climate change

Cities located in metropolitan areas of this Brazilian state score better according to an index that measures the existence of public policies designed to adjust critical sectors to the impacts of climate change.

Increase in deforestation of the Amazon threatens Brazil’s ability to achieve its climate goals

Illegal logging to clear land for cattle grazing has fueled growth in Brazil’s greenhouse gas emissions, according to participants in a webinar on the prospects for COP26 hosted by FAPESP.
