Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900)
Explanation:
this is happening due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
The first plantation crop that Europeans, particularly the Portuguese, grew on the plain of Northeast Brazil was sugar. They established large sugar plantations using enslaved Africans for labor, and the harsh, labor-intensive work of sugar production greatly contributed to the development of Brazil as a significant player in the international sugar market.
The first plantation crop that Europeans grew on the plain of Northeast Brazil was sugar. When Europeans, largely the Portuguese, first settled in Brazil, they established systems of racially based slavery, as they identified the need for a large, skilled labor force to cultivate crops.
The land was fitting for growing a variety of crops such as coffee, rice, and cotton, but the first crop to be cultivated on a large scale was sugar. The Portuguese were already using enslaved Africans to grow sugar on islands off the West African coast and saw the opportunity to expand this production process to Brazil. In the process, they created large sugar plantations, fulfilling the ever-growing international demand for this product.
The work on sugar plantations was labor-intensive and dangerous. Workers cut the cane stalks by hand, carried them to a mill for the juice to be extracted, then boiled the juice down to a brown, crystalline sugar. This sugar was then cured in special houses to drain the molasses. The sugar production turned Brazil, particularly the Northeast region, into a key player in the international sugar market.

Answer:
Weather forecasts and severe weather alerts are issued by the National Weather Service.
Explanation:
The National Weather Service (NWS) is responsible for providing alerts and warnings about the weather, hydrological and climatic conditions of the United States.
Through national and regional centers, they report on the climatic conditions of the United States as well as in adjacent waters and the oceanic area.
Its services are provided to the public free of charge and it is one of the six scientific agencies that is part of the National Oceanic and Atmospheric Administration of the government.
