The mathematician Vernor Vinge popularized his ideas about exponentially accelerating technological change in the science fiction novel Marooned in Realtime (1986), set in a world of rapidly accelerating progress leading to the emergence of more and more sophisticated technologies separated by shorter and shorter time intervals, until a point ...
Global change in broad sense refers to planetary-scale changes in the Earth system. It is most commonly used to encompass the variety of changes connected to the rapid increase in human activities which started around mid-20th century, i.e., the Great Acceleration.
Each of these effects occur cyclically. For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05. [45] [46] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively. [47]
The rate Earth is warming hit an all-time high in 2023 with 92% of last year's surprising record-shattering heat caused by humans, top scientists calculated. The group of 57 scientists from around ...
Gleason’s conclusion: “Holy cow, the rivers of the world are a lot different than we thought.” Some are changing by 5% or 10% a year, the report found. “That’s rapid, rapid change,” he ...
The world may already have hit 1.5 degree Celsius (2.7 F) of warmin ... The last global scientific consensus on climate change was released in 2021 through the Intergovernmental Panel on Climate ...
The Great Acceleration is the dramatic, continuous and roughly simultaneous surge across a large range of measures of human activity, first recorded in the mid-20th century and continuing into the early 21st century.
The Green Revolution (1945–1975): the use of industrial fertilizers and new crops largely increased the world's agricultural output. The Third Industrial Revolution: the changes brought about by computing and communication technology, starting from around 1950 with the creation of the first general-purpose electronic computers.
