Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%.

Cows produce 150 billion gallons of methane per day. 250-500 liters per cow per day, x 1.5 billion cows globally is 99 – 198.1 billion gallons.

Cows and Pollution FAQ Statistically, yes. Researchers say that cows produce, on average, about 100 to 200 liters (26 to 53 gallons) of methane per day through belching. Some even raise the figure up to 500 liters (about 132 gallons) of methane in one day.

For every gram of beef produced, 221 grams of carbon dioxide is emitted, compared to 36 for pork. And for every calorie from beef, 22 grams of carbon dioxide is emitted, compared to 3.5 from pork.

Hence, according to the United Nations Food and Agriculture Organization (FAO) livestock generate 18 percent of total greenhouse gas emissions as measured in CO2 equivalents — more than the entire transport sector, automobiles, trains, ships, and planes. …

Which is actually worse—cows or cars? Livestock emissions make up anywhere between 14.5 and 18 percent of total global greenhouse gas emissions. Yes, driving cars is no good, but meat production is unexpectedly worse for the environment.

Here we see that electricity and heat production are the largest contributor to global emissions. This is followed by transport, manufacturing and construction (largely cement and similar materials), and agriculture.

• Industrialization. The transition of economies from primarily farming-based to primarily industrial is likely to have been the earliest cause of the rampant global warming we see today.
• Deforestation.
• Livestock Production.
• Factory Farming.
• Use of Aerosols.
• Inability to Change.

Over the past 100 years, global temperatures have risen about 1 degree C (1.8 degrees F), with sea level response to that warming totaling about 160 to 210 mm (with about half of that amount occurring since 1993), or about 6 to 8 inches.

Many small island nations will be catastrophically affected by sea-level rises in the future, including The Bahamas, which was devastated by Hurricane Dorian in 2019. Most of Grand Bahama, including Nassau (pictured), Abaco and Spanish Wells are projected to be underwater by 2050 because of climate change.

From the Paris Agreement period alone—between 2015, when the agreement was signed, and 2030, when the stated commitments end—the world will have caused enough warming to drive sea levels about 4.5 inches higher in the future. That’s just from that 15-year stretch.

According to the Fourth (2017) National Climate Assessment (NCA) of the United States it is very likely sea level will rise between 30 and 130 cm (1.0–4.3 feet) in 2100 compared to the year 2000.

Ice melting from land into the ocean, warming waters that expand, a slowing Gulf Stream, and sinking land all contribute to sea level rise. Although a global phenomenon, the amount and speed of sea level rise varies by location, even between the East and the West Coasts.

Most neighborhoods in Charleston, South Carolina, could be underwater by 2100. Charleston is even more vulnerable to flooding than Atlantic City, with around 64,000 of its residents at risk of coastal flooding in the next 100 years.

about 70 meters

Even if we significantly curb emissions in the coming decades, more than a third of the world’s remaining glaciers will melt before the year 2100. When it comes to sea ice, 95% of the oldest and thickest ice in the Arctic is already gone.

Antarctica is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet).

The current sea level is about 130 metres higher than the historical minimum. Historically low levels were reached during the Last Glacial Maximum (LGM), about 20,000 years ago. The last time the sea level was higher than today was during the Eemian, about 130,000 years ago.

During the peak of the last Ice Age (~20,000 years ago), sea level was ~120 m lower than today. As a consequence of global warming, albeit naturally, the rate of sea-level rise averaged ~1.2 cm per year for 10,000 years until it levelled off at roughly today’s position ~10,000 years ago.

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.

Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth’s climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.

According to the World Meteorological Organization (WMO), the highest registered air temperature on Earth was 56.7 °C (134.1 °F) in Furnace Creek Ranch, California, located in Death Valley in the United States, on 10 July 1913, This record was surpassed in 1922 by a reading of 57.8 °C (136.0 °F), registered on 13 …

New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth’s axis was approaching higher values.

But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago. All apes and monkeys share a more distant relative, which lived about 25 million years ago.
