How much has sea level risen in 100 years?

Sea levels have risen by approximately 8 inches (20 cm) over the past century. This rise is primarily due to the melting of glaciers and ice caps, as well as the thermal expansion of seawater caused by global warming. Continued sea level rise is expected in the future due to ongoing climate change.


How much hotter is the earth since the levels of carbon dioxide went up?

The Earth's average temperature has increased by about 1°C (1.8°F) since the late 19th century, primarily due to increased levels of carbon dioxide and other greenhouse gases in the atmosphere. This warming trend is expected to continue unless significant reductions in greenhouse gas emissions are achieved.


How much has the average temperature risen in the greenhouse effect?

0.8 degrees Celsius, since 1850. 1850 was a known low temp referred to as the mini ice age. The total warming started roughly 10,200 years ago and is, in total, about 11 degrees C. 0.6 of the current warming occurred before World War 2. The temperature dropped for a few decades in the 1970's despite increasing use of fuel. 2010 tied with 2005 as the warmest years on record. The ten hottest years have all happened since 1998.

Why are ocean levels lower in the ice age then now?

During the ice age, much of the Earth's water was locked up in large ice sheets, causing sea levels to be lower than they are today. As the ice sheets melted and retracted over time, the water they released flowed into the oceans, gradually raising sea levels to their current levels.

How have the levels of carbon dioxide and oxygen changed since the big bang?

Since the Big Bang, the levels of carbon dioxide and oxygen have changed significantly. Carbon dioxide levels were initially much higher due to volcanic activity, but then decreased as photosynthetic organisms evolved and absorbed CO2 to produce oxygen. Oxygen levels gradually increased as a result of this photosynthesis, leading to the oxygen-rich atmosphere we have today.
