Researchers have developed global forecasts that can provide up to a year's advance notice of marine heatwaves, sudden and pronounced increases in ocean temperatures that can dramatically affect ocean ecosystems. The forecasts described in the journal Nature could help fishing fleets, ocean managers, and coastal communities anticipate the effects of marine heatwaves. One such heatwave, known as “the Blob,” emerged about 2013 in the northeast Pacific Ocean and persisted [...]

Deforestation for agribusiness expansion in Brazil, in conjunction with climate change, has worsened the already severe drought suffered in the last decade by the transition zone between the eastern Amazon and the Cerrado, the vast tropical savanna ecoregion in central and western Brazil.

Even the finest particles of pollution influence the process of cloud formation and the rainfall regime. A study conducted in Manaus, the capital of Amazonas state in Brazil’s North region, shows that oxidation leads small aerosols expelled by factories and car exhausts, for example, to grow very rapidly, reaching up to 400 times their original size, and that this affects raindrop formation. Even the finest particles of pollution influence the process of cloud formation and the [...]

In 2019, history student Rodrigo Gomes found out on social media about a call for volunteers to take part in a scientific project relating to the ocean and conducted by the Federal University of São Paulo’s Institute of Marine Sciences (IMAR-UNIFESP) in Santos, on the coast of the state of São Paulo, Brazil. He signed up for the project, took workshops, and trained in the field. “I was very fortunate to have all that contact with professors and learned a great deal [...]

A study by an international group of researchers shows that interaction between communities of plankton – microorganisms that live at the bottom of the food chain in the oceans and supply most of the planet’s oxygen – will be affected by climate change in different ways depending on location.

Mathematical models that describe the physical behavior of magnetic materials can also be used to describe the spread of the novel coronavirus that causes COVID-19. Mathematical models that describe the physical behavior of magnetic materials can also be used to describe the spread of the novel coronavirus that causes COVID-19. This is the conclusion of a study conducted in Brazil by researchers affiliated with São Paulo State University (UNESP) in Rio Claro and Ilha Solteira and [...]

Albeit very small, with a carapace width of only 3 cm, the Atlantic mangrove fiddler crab Leptuca thayeri can be a great help to scientists seeking to understand more about the effects of global climate change. In a study published in the journal Estuarine, Coastal and Shelf Science, Brazilian researchers supported by FAPESP show how the ocean warming and acidification forecast by the end of the century could affect the lifecycle of these crustaceans.  Embryos of L. thayeri were exposed [...]

Several indicators point to the adverse impacts of climate change on the planet’s vegetation, but a little-known positive fact is the existence of climate-change refugia in which trees are far less affected by the gradual rise in temperatures and changing rainfall regimes. Climate-change refugia are areas that are relatively buffered from climate change, such as wetlands, land bordering water courses, rocky outcrops, and valleys with cold-air pools or inversions, for example. A study [...]

White-sand savannas are expanding in the heart of the Amazon as a result of recurring forest fires, according to a study published in the journal Ecosystems. White-sand savannas are expanding in the heart of the Amazon as a result of recurring forest fires, according to a study published in the journal Ecosystems. The study was supported by FAPESP, and conducted by Bernardo Monteiro Flores, currently a postdoctoral fellow in ecology at the Federal University of Santa Catarina (UFSC) in [...]
