The World Meteorological Organisation (WMO) announces that it assesses a 20% chance that global warming compared to pre-industrial levels will exceed 1.5 °C in at least one year within the five years of 2020–2024. 1.5 °C is often considered to be a key threshold of global warming and nations have agreed to attempt limiting contemporary ...
Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [7] to 25.2% in 2020 in single-junction architectures, [8] and, in silicon-based tandem cells, to 29.1%, [8] exceeding the maximum efficiency achieved in single-junction silicon solar cells.

As of July 2020, neither the International Commission on Stratigraphy (ICS) nor the International Union of Geological Sciences (IUGS) has officially approved the term as a recognized subdivision of geologic time, [1] [2] [3] but in May 2019, the AWG voted in favor of submitting a formal proposal to the ICS by 2021, [4] locating potential stratigraphic markers to the mid-twentieth century of ...
Paleontologists report the discovery of 1 billion-year-old micro-fossils of 2 mm sized green seaweeds called Proterocladus antiquus. The algae could produce oxygen via photosynthesis and is a close relative of the ancestor of all contemporary green plants including land plants which evolved ca. 450 million years ago.
The Global Carbon Budget 2021 concludes that fossil CO 2 emissions rebounded by around +4.8% relative to 2020 emissions – returning to 2019 levels, identifies three major issues for improving reliable accuracy of monitoring, shows that China and India surpassed 2019 levels (by 5.7% and 3.2%) while the EU and the US stayed beneath 2019 levels ...
