The COVID-19 pandemic was confirmed in Jamaica on 10 March 2020. This was during the 2019–2020 dengue fever epidemic that affected Latin America and the Caribbean. On 11 January 2022, Jamaica overtook China in terms of the number of confirmed cases.
In January 2021 scientists reported that reductions in air pollution due to worldwide COVID-19 lockdowns in 2020 were larger than previously estimated. It was concluded that, because of the impact of the COVID-19 pandemic on the climate during that year, a slight warming of Earth's climate during the year was seen instead of a slight cooling.
The Global Carbon Project estimated that global daily CO 2 emissions may have been reduced by 17% during the most intense periods of COVID-19 shutdowns, but the WMO's Greenhouse Gas Bulletin indicated that this short-term impact cannot cause 2020's annual figure to exceed the 1 ppm natural inter-annual variability.

With 21% of global methane emissions, cattle are a major driver of global warming. [ 225 ] : 6 When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO 2 -eq. [ 226 ] Other livestock, manure management and rice cultivation also emit ...
Even if nations meeting in Paris curtail carbon emissions, a growing number of communities will be exposed to threats caused by climate change. Vulnerable populations that live near water or in arid places will face massive disruptions to their way of life: Flooding and severe drought are on course to become much more common. +2 degrees +4 degrees
Global Container Freight Index, July 2019 – August 2022. In 2021, as a consequence of the COVID-19 pandemic and, later, the ongoing 2022 Russian invasion of Ukraine, global supply chains and shipments slowed, causing worldwide shortages and affecting consumer patterns. Causes of the economic slowdown included workers becoming sick with COVID ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [28]
