Circa , Nicolaus Copernicus developed his own celestial model of a heliocentric planetary system. Around , he shared his findings in the Commentariolus. His second book on the topic, De revolutionibus orbium coelestium , was banned by the Roman Catholic Church decades after his May 24, death in Frombork. The fourth and youngest child born to Nicolaus Copernicus Sr. By the time he was born, Torun had ceded to Poland, rendering him a citizen under the Polish crown. German was Copernicus’ first language, but some scholars believe that he spoke some Polish as well. During the mids, Copernicus’ father passed away. His maternal uncle, Bishop of Varmia Lucas Watzenrode, generously assumed a paternal role, taking it upon himself to ensure that Copernicus received the best possible education.

Earth Day is an annual event created to celebrate the planet’s environment and raise public awareness about pollution. The day, marked on April 22, is observed worldwide with rallies, conferences, outdoor activities and service projects. The idea for Earth Day was proposed by then-Sen. Gaylord Nelson of Wisconsin, who died in The first Earth Day was in

Incheon, Republic of Korea, October 8 — Limiting global warming to 1. With clear benefits to people and natural ecosystems, limiting global warming to 1. The Special Report on Global Warming of 1. It will be a key scientific input into the Katowice Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change. The report highlights a number of climate change impacts that could be avoided by limiting global warming to 1.
For instance, by , global sea level rise would be 10 cm lower with global warming of 1. The likelihood of an Arctic Ocean free of sea ice in summer would be once per century with global warming of 1. Coral reefs would decline by percent with global warming of 1. The report also examines pathways available to limit warming to 1. The report finds that limiting global warming to 1.
5 Things to Think About Before You Sign on for a Minor

ID card and for those who want to take the first step towards a driver’s licence. You can now make an appointment to complete the knowledge test for a class seven learner’s licence. The challenge for ICBC to restart road tests is the need for personal protective equipment PPE to prevent the spread of the virus between the driving evaluator and the person taking the test.

Greenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.
Human-induced warming and associated sea level rises are expected to continue through the 21st century. Secondary effects are suggested by computer model simulations and basic physical reasoning. These include increases in rainfall rates and increased susceptibility of semi-arid regions to drought. The impacts of these changes will be critically dependent on the magnitude of the warming and the rate with which it occurs.
The mid-range model estimate of human induced global warming by the Intergovernmental Panel on Climate Change IPCC is based on the premise that the growth rate of climate forcing 1 agents such as carbon dioxide will accelerate.

Aristotle thought the earth had existed eternally. Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being. Within decades observation began overtaking such thinking.
In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil. This position came to be known as uniformitarianism, but within it we must distinguish between uniformity of natural law which nearly all of us would accept and the increasingly questionable assumptions of uniformity of process, uniformity of rate and uniformity of outcome.
That is the background to the intellectual drama being played out in this series of papers. It is a drama consisting of a prologue and three acts, complex characters, and no clear heroes or villains. We, of course, know the final outcome, but we should not let that influence our appreciation of the story as it unfolds. Even less should we let that knowledge influence our judgment of the players, acting as they did in their own time, constrained by the concepts and data then available.
One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists. Most notable is William Thomson, ennobled to become Lord Kelvin in , whose theories make up an entire section of this collection. He was one of the dominant physicists of his time, the Age of Steam.

In the fall of , for a time capsule, students draw pictures of life as they imagine it will be in 50 years. Lucinda, an odd child who hears voices, swiftly writes a long string of numbers. In , the capsule is opened; student Caleb Koestler gets Lucinda’s “drawing” and his father John, an astrophysicist and grieving widower, takes a look. He discovers dates of disasters over the past 50 years with the number who died. Three dates remain, all coming soon.

Hadean Eon , informal division of Precambrian time occurring between about 4. Throughout part of the eon , impacts from extraterrestrial bodies released enormous amounts of heat that likely prevented much of the rock from solidifying at the surface. As such, the name of the interval is a reference to Hades , a Greek translation of the Hebrew word for hell.
Convection currents in the mantle brought molten rock to the surface and caused cooling rock to descend into magmatic seas. Heavier elements, such as iron , descended to become the core, whereas lighter elements, such as silicon , rose and became incorporated into the growing crust. Although no one knows when the first outer crust of the planet formed, some scientists believe that the existence of a few grains of zircon dated to about 4. Since Hadean times, nearly all of this original crust has subducted from the movements of tectonic plates , and thus few rocks and minerals remain from the interval.
The oldest rocks known are the faux amphibolite volcanic deposits of the Nuvvuagittuq greenstone belt in Quebec, Canada; they are estimated to be 4. The oldest minerals are the aforementioned grains of zircon, which were found in the Jack Hills of Australia.

Earth Day was founded in as a day of education about environmental issues, and Earth Day will occur on Thursday, April 22—the holiday’s 51st anniversary. By raising public awareness of pollution, Nelson hoped to bring environmental causes into the national spotlight. By the early s, Americans were becoming aware of the effects of pollution on the environment. Factories pumped pollutants into the air, lakes and rivers with few legal consequences. Big, gas-guzzling cars were considered a sign of prosperity.
Only a small portion of the American population was familiar with—let alone practiced—recycling.
