Launched in April 2006 as a statistical machine translation service, it used United Nations and European Parliament documents and transcripts to gather linguistic data. Rather than translating languages directly, it first translates text to English and then pivots to the target language in most of the language combinations it posits in its grid,[4], with a few exceptions including Catalan-Spanish.[5] During a translation, it looks for patterns in millions of documents to help decide on which words to choose and how to arrange them in the target language. Its accuracy, which has been criticized and ridiculed on several occasions,[6] has been measured to vary greatly across languages.[7] In November 2016, Google announced that Google Translate would switch to a neural machine translation engine - Google Neural Machine Translation (GNMT) - which translates "whole sentences at a time, rather than just piece by piece. It uses this broader context to help it figure out the most relevant translation, which it then rearranges and adjusts to be more like a human speaking with proper grammar".[8] Originally only enabled for a few languages in 2016, GNMT is used in all 109 languages in the Google Translate roster as of 2020, except for Kyrgyz, Latin, and the Belarusian, Maltese and Sundanese to other languages pairs.[9]

Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."

The history of science is the study of the development of science and scientific knowledge, including both the natural and social sciences (the history of the arts and humanities is termed history of scholarship). Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real-world phenomena. Historiography of science, in contrast, studies the methods employed by historians of science.The history of science is the study of the development of science and scientific knowledge, including both the natural and social sciences (the history of the arts and humanities is termed history of scholarship).

Warning Signs a Child Is Being Cyberbullied or Is Cyberbullying
A child may be involved in cyberbullying in several ways. A child can be bullied, bully others, or witness bullying. Parents, teachers, and other adults may not be aware of all the social media platforms and apps that a child is using. The more digital platforms that a child uses, the more opportunities there are for being exposed to potential cyberbullying. 
Many of the warning signs that cyberbullying is occurring happen around a child’s use of their device. Since children spend a lot of time on their devices, increases or decreases in use may be less noticeable. It’s important to pay attention when a child exhibits sudden changes in digital and social behavior. Some of the warning signs that a child may be involved in cyberbullying are:

Noticeable, rapid increases or decreases in device use, including texting.
A child exhibits emotional responses (laughter, anger, upset) to what is happening on their device.
A child hides their screen or device when others are near, and avoids discussion about what they are doing on their device.
Social media accounts are shut down or new ones appear.
A child starts to avoid social situations, even those that were enjoyed in the past.
A child becomes withdrawn or depressed, or loses interest in people and activities.
