Global Temperatures facts
While investigating facts about Global Temperatures By Year and Global Temperatures History, I found out little known, but curios details like:
It’s doubtful that dinosaurs would be able to survive today. During the Cretaceous Period 145-66 million years ago the average global temperature was 4ºC higher than today, with little difference between the temperature of the equator and the poles
how much have global temperatures risen?
Laki is one of the deadliest volcanoes in the world. It erupted in 1783 which caused famine and killed 25% of Iceland’s population, it also caused a drop in global temperature which resulted in crop failures in Europe and droughts in India. It estimated to kill over 6 million people globally.
What is causing global temperatures to rise?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering as global temperatures continue to rise what is a likely outcome. Here are 38 of the best facts about Global Temperatures Over Time and Global Temperatures 2019 I managed to collect.
what happens if global temperatures rise?
-
The temperature of the earth has increased by one half of a degree Celsius in the last 100 years, which might seem small but it can have drastic effects on the earth as a whole. This temperature change can melt ice caps and cause water levels to rise globally.
-
Krakatoa's eruption was four times more powerful than the Tsar Bomb (200 megatons) and was so enormous, it lowered global temperature by 2.2 degrees for the next five years.
-
The average global temperature during the last ice age was only about 5°C / 9°F less than the average today.
-
Because of the increase in temperature, ice caps have begun melting causing the sea level to rise.
-
According to NASA, "...a one- to two-degree drop [in the global temperature] was all it took to plunge the Earth into the Little Ice Age. A five-degree drop was enough to bury a large part of North America under a towering mass of ice 20,000 years ago."
-
The Arctic ice is protective for the planet as it reflects some of the harsh sun's rays back into space, which in turn helps to regulate the temperature of the earth. Global warming and melting of the ice cap threatens the earth because of this.
-
The Year 1816, known as the Year Without a Summer caused by the massive 1815 eruption of Mount Tambora, which caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1.3 °F)
-
Global warming can cause hot temperatures where it used to be cold and cold temperatures where it used to be warm. This disrupts the life cycle in many regions and could result in increased water levels and flooding around the world due to melting ice caps. Only 1 yard rise in sea level would result in more than 100 million people losing their homes and communities.
-
Detonating 100 Hiroshima-sized nuclear bombs, anywhere in the world, could potentially generate enough black smoke to partially block the sunlight, resulting in massive temperature drops, disruption of the global climate and worldwide famine
-
1816 is known as the Year Without a Summer. Average global temperatures decreased by 0.4 - 0.7 degrees Celsius, leading to massive crop failures and food shortages. Frost occurred throughout the summer months, and Maine and upstate New York experienced snowfall in June.

What is true about global temperatures?
You can easily fact check it by examining the linked well-known sources.
1816 was called the "Year Without a Summer". Volcanic activity the year before caused a major decrease in global temperature. Frost and snow destroyed crops, leading to famine in many places.
An increase in temperature and sea level causes algae to be stressed due to the decrease in sunlight.
The eruption of 1815 Mount Tambora could be heard from a distance of 2500 kilometers (=1550 miles). It blew so much ash in the atmosphere, sunlight got blocked and global temperature dropped, causing freezing temperatures and frost during the summer of 1816, nicknamed "The Year Without a Summer" - source
As global temperatures rise, flowers are emitting less scent.
Nuclear Winter: Global precipitation would drop by around 45%. Surface temperatures plunge 17F to 20F. Almost nothing would grow, ensuring starvation. The depleted ozone layer allows ultraviolet light to surface. A Caucasian person couldn’t go outside for a few minutes before getting a sunburn. - source
What happens when global temperatures increase?
Tuatara (part of a lizard-like order separate from all other reptiles) are so sensitive to temperature that, at 21C, all babies are female, and at 22C, all babies are male. Thus, global warming has directly led to major conservation challenges.
How scientists learn about past global temperatures and climates?
The 1815 eruption of Mount Tambora was classified a "Mega-colossal" eruption, and reduced global temperatures, creating the "year without summer"
One dinosaur extinction theory says they were cooked alive in just 2 hours after the asteroid struck, as sand-size glass balls rained down all over the earth, causing global temperatures to reach 1200F.
If you're under 38 years old, you've never experienced a year in which the global average surface temperature was at or below average.
The “thermal exclusionary zone,” which protects us from most fungal infections due to mammal’s relatively high body temperature, is shrinking because of global warming. For every degree of warming “We will lose 15% vs 7.5% of our protection against invasive and deadly fungal pathogens.”
