The record drought in the Brazilian Amazon in 2023 was caused by climate change, Azernews reports, citing foreign media outlets. This conclusion was reached by an international team of scientists from the Center for the Study of Weather Phenomena World Weather Attribution (WWA). “The main cause of the record drought in 2023 in the Amazonian region of Brazil was climate change caused by human activity,” says the report posted on the organization’s website. According to scientists, the influence of the El Nino phenomenon on the weather in the Amazon basin turned out to be much weaker than experts had expected. “Climate change leads to an increase in temperature and a decrease in precipitation. These factors increased the probability of an unprecedented drought in 2023 by 30 times compared to a situation in which the only factor influencing the weather would be El Nino,” the authors of the study note. Meteorologists f...

E-commerce may make shopping more convenient, but it has a dark side that most consumers never see. Say you order an electric toothbrush and two shirts for yourself during a sale on Amazon. You unpack your order and discover that the electric toothbrush won’t charge and only one shirt fits you. So, you decide to return the unwanted shirt and the electric toothbrush. Returns like this might seem simple, and often they’re free for the consumer. But managing those returns can get costly for retailers, so much so that many returned items are simply thrown out. In 2022, returns cost retailers about US$816 billion in lost sales. That’s nearly as much as the U.S. spent on public schools and almost twice the cost of returns in 2020. The return process, with transportation and packaging, also generated about 24 million metric tons of planet-warming carbon dioxide emissions in 2022. Together, costs and emissions create a sustainability problem for retailers and the p...

Conservationists breathed a sigh of relief when Luiz Inácio Lula da Silva won Brazil’s presidential election in the fall of 2022. His predecessor, Jair Bolsonaro, had opened large parts of the Amazon region to business by crippling enforcement of environmental laws and turning a blind eye to land grabbing. It should come as no surprise that deforestation showed a sharp uptick. However, while Lula oversaw a more than 70% drop in deforestation during his first run as president in the early 2000s, the rainforest’s future remains deeply uncertain. That’s in part because Brazilian administrations, whether of the right or left, have all promoted an ambitious project to boost exports and the economy called the Initiative for the Integration of the Regional Infrastructure of South America, or IIRSA. The initiative focuses on new roads, dams and industry that can threaten the region’s fragile rainforest ecosystem – and harm the world’s climate i...

An unwelcome visitor is headed for Florida and the Caribbean: huge floating mats of sargassum, or free-floating brown seaweed. Nearly every year since 2011, sargassum has inundated Caribbean, Gulf of Mexico and Florida coastlines in warm months, peaking in June and July. This brown tide rots on the beach, driving away tourists, harming local fishing industries and requiring costly cleanups. According to scientists who monitor the formation of sargassum in the Atlantic Ocean, 2023 could produce the largest bloom ever recorded. That’s bad news for destinations like Miami and Fort Lauderdale that will struggle to clean their shorelines. In 2022, Miami-Dade County spent US$6 million to clear sargassum from just four popular beaches. Satellite image of sargassum concentrations in the Atlantic during the month of March.

Brazil’s president-elect, Luiz Inácio Lula da Silva, was greeted with applause and cheers when he addressed the U.N. climate conference in Sharm el-Sheikh, Egypt, on Nov. 16, 2022. As he had in his campaign, Lula pledged to stop rampant deforestation in the Amazon, which his predecessor, Jair Bolsanaro, had encouraged. Forests play a critical role in slowing climate change by taking up carbon dioxide, and the Amazon rainforest absorbs one-fourth of the CO2 absorbed by all the land on Earth. These articles from The Conversation’s archive examine stresses on the Amazon and the Indigenous groups who live there. 1. Massive losses The Amazon rainforest is vast, covering some 2.3 million square miles (6 million square kilometers). It extends over eight countries, with about 60% of it in Brazil. And the destruction occurring there is also enormous. From 2010 to 2019, the Amazon lost 24,000 square miles (62,000 square kilometers) of forest – the equivalent of...
