- Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.limate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past century, another force has started to influence Earth’s climate: humanity.

Global warming Sea level rise, has been estimated to be on average +2.6 mm and +2.9 mm per year ± 0.4 mm since 1993. Additionally, sea level rise has accelerated in recent years. Over the 21st century, the IPCC projects for a high emissions scenario, that global mean sea level could rise by 52–98 cm.nticipated effects include warming global temperature, rising sea levels, changing precipitation, and expansion of deserts in the subtropics. Warming is expected to be greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice.

- Snow cover on land is also dwindling in many areas. In the absence of snow and ice, these areas go from having bright, sunlight-reflecting surfaces that cool the planet to having dark, sunlight-absorbing surfaces that bring more energy into the Earth system and cause more warming.Canada’s Athabasca Glacier has been shrinking by about 15 meters per year.odel simulations by the Intergovernmental Panel on Climate Change estimate that Earth will warm between two and six degrees Celsius over the next century, depending on how fast carbon dioxide emissions grow.

- Some of their key findings include: 1  The warming trend over the last 50 years (about 0.13° C or 0.23° F per decade) is nearly twice that for the last 100 years. 2  The average amount of water vapor in the atmosphere has increased since at least the 1980s over land and ocean. The increase is broadly consistent with the extra water vapor that warmer air can hold. Since 1961, the average temperature of the global ocean down to depths of at least 3 km (1.9 miles) has increased.

- Global Warming: A Natural Process The Earth’s current CO2 level is at 393.84ppm (CO2now, 2013). This is the highest of the high levels in the past 450,000 years. Extra carbon dioxide in the air is believed to keep temperatures steady and contributing to the greenhouse effect which causes the planet to warm.

How much will Earth warm if carbon dioxide doubles pre-industrial levels? Scientists say that doubling pre-industrial carbon dioxide levels will likely cause global average surface temperature to rise between 1.5° and 4.5° Celsius (2.7° to 8.1° Fahrenheit) compared to pre-industrial temperatures.

Temperature on Earth Global warming has also caused an increase in the average surface temperature of the Earth over the last 150 years. Average temperatures on the planet have risen by 0.8° C since the 1880s, with the worst increases occurring over the past few decades. In fact, the last two decades of the twentieth century were among the hottest in 400 years.

- How to Prepare for Global Warming. Global warming is the gradual increase of the earth's atmospheric temperature. The cause of global warming is the increase of greenhouse gas in the environment. Greenhouse gas comes from carbon dioxide emissions, chlorofluorocarbons and other damaging pollutants.

- The term global warming refers to the increase in the average temperature of global surface air and oceans since about 1950, and to continuing increases in those temperatures.

The Link Between Global Warming and Terrorists According to the leading scientific advocates of climate change theory, the global mean temperature has risen less than one degree Celsius since 1880. Let's imagine that the pace of warming is accelerating and that the mean temperature shall rise by a whole degree or two over, say, the next thirty or forty years.

Effects of Global Warming Here is an in-depth look at the changes wrought by global warming. Increase in average temperatures and temperature extremes. One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Oceanic and Atmospheric Administration (NOAA).

Earthâs tectonic plates have doubled their speed The average rate of continental collisions, and the average speed with which the continents change latitude, has doubled over the last 2 billion years (Precambrian Research, doi.org/vbv). “We expected to find that the average speed would be slowing down with time, but we didn’t get that.

How much has the global temperature risen since 1880? How much has the global temperature risen since 1880? Averaged over all land and ocean surfaces, temperatures warmed roughly 1.53 degrees Fahrenheit (0.85 degrees Celsius) from 1880 to 2012, according to the Intergovernmental Panel on Climate Change (see page 3 of the 2013 summary report). Because oceans tend to warm and cool more slowly than land areas, continents have warmed the most. In the Northern Hemisphere, where most of Earth's land mass is located, the three decades from 1983 to 2012 were likely the warmest 30-year period of the last 1,400 years, according to the IPCC.

- Sea levels are rising. Global sea level has increased by roughly 8 inches over the past century, and the rate of increase is accelerating. Global warming causes sea-level rise in two ways: (1) Ocean water is expanding as it warms. (2) Land-based ice in glaciers and ice sheets is melting.

- 1 The argument is that since the effect of CO2 is logarithmic and the increase in CO2 is almost linear the rate of warming should slow down in later years. 2  I wish woodfortrees had a handy app for this but they don't. 3  I pulled the CO2 data for 58 years into excel and did a simple log of the data.
