The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at
Some meteorologists have disputed how accurate Death Valley's 110-year-old high is, with the weather historian Christopher Burt disputing it for several reasons, which he laid out in a blogpost a few years ago. The two hottest temperatures on record are the 134F in 1913 in Death Valley and 131F in Tunisia in July 1931.
The climate of the Jurassic was generally warmer than that of present, by around 5 °C to 10 °C, with atmospheric carbon dioxide likely four times higher.
The Industrial Age and global warming
Scientists generally have argued that man-made climate change caused by greenhouse gas emissions began in the late 1800s.
Tree rings and ice cores (from 1,000–2,000 years before present) Proxy measurements can be used to reconstruct the temperature record before the historical period.
Their research suggests that Earth's surface cooled from roughly 167o F (75o C) about 3 billion years ago to roughly 95o (35o F) about 420 million years ago. These findings are consistent with previous geological and enzyme-based results.
Even after those first scorching millennia, however, the planet has often been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago.
Many workstations would be replaced by robots. There would also be new and faster means of transportation – Maybe even flying cars. Our climate would continue to increase in temperature. The world population would increase by several billion and therefore our field and forests would disappear and become cities.
Very hot. During this Mesozoic Era — from about 250 to 66 million years ago — the concentrations of CO2 in the atmosphere were around 16 times higher than now, creating a "greenhouse climate” with temperatures on average six to nine degrees warmer than today.
Last Glacial Maximum- a time, around 20,000 years ago, when much of the Earth was covered in ice. The average global temperature may have been as much as 10 degrees Celsius colder than that of today. The Earth has a long history of cycles between warming and cooling.
At least five major ice ages have occurred throughout Earth's history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago.
When the 6-mile-wide asteroid that led to dinosaur extinction hit Earth 66 million years ago, the impact also triggered a “mega-earthquake” that lasted weeks to months, new evidence suggests.
The air the dinosaurs breathed was in fact much richer in oxygen than now, and is the reason why winged reptiles of those days had (as creationists never tire of pointing out) pinions too small to work in today's atmosphere.
The highest temperature ever recorded in Australia is 50.7 °C (123.3 °F), which was recorded on 2 January 1960 at Oodnadatta, South Australia, and 13 January 2022 at Onslow, Western Australia. The lowest temperature ever recorded in Australia is −23.0 °C (−9.4 °F), at Charlotte Pass, New South Wales, on 29 June 1994.
The hottest thing in the Universe (Supernova)
Supernovas are the hottest thing in the Universe as they reach a million degrees Celsius. These explosive events occur when a star between 8 and 40 times more massive than our Sun reaches the end of its stellar lifecycle and explodes when its core collapses. What is this?
A wet-bulb temperature of 35 °C, or around 95 °F, is pretty much the absolute limit of human tolerance, says Zach Schlader, a physiologist at Indiana University Bloomington. Above that, your body won't be able to lose heat to the environment efficiently enough to maintain its core temperature.
Prior to the Oligocene, and into the Mesozoic, the world had little or no polar ice (there is still debate as to the exact measure of 'little or no').
In the beginning the surface of the Earth was extremely hot, because the Earth as we know it is the product of a collision between two planets, a collision that also created the Moon. Most of the heat within the very young Earth was lost quickly to space while the surface was still quite hot.
Over the past 4.5 billion years, the Sun has gotten hotter, but also less massive. The solar wind, as we measure it today, is roughly constant over time.
There are fears that a powerful geomagnetic storm in the year 2025 can destroy the Earth. An NYU professor believes there is a likelihood that such an event can happen.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
Heatwaves will be more frequent and long-lasting, causing droughts, global food shortages, migration, and increased spread of infectious diseases. Moreover, as the polar ice will melt, sea levels will rise substantially, affecting a large number of coastline cities and as many as 275 million of their inhabitants.
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earth's climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
The rate at which the sun is slowing is also tiny (around 3 milliseconds every 100 years). As the sun loses its momentum and mass, the Earth can slowly slip away from the sun's pull. Our planet is assuredly not growing closer to the sun in orbit; in fact, our planet is slowly inching away from the sun.
While the Sun is not getting hotter, the amount of radiation being trapped in Earth's atmosphere is increasing due to the burning of fossil fuels. When heat can't escape Earth's atmosphere, changes to Earth's energy budget causes rapid climate change, at a rate in which biological life has trouble adapting.
