In a warming world, based upon simple physical principles we would expect some indicators to increase land surface air temperature, sea-surface temperature, marine air temperature, sea level, tropospheric temperature, ocean heat content and specific humidity.
- Arctic sea ice extent is diminishing.
- Ocean heat content is increasing.
- Air temperature over ocean is increasing.
- Sea surface temperature is increasing.
- Global sea level is rising.
- Humidity is increasing.
- Temperature of the lower atmosphere is increasing.
- Air temperature over land is increasing.
What are four expected impacts of global warming?
These include:
- Sea levels are expected to rise between 10 and 32 inches (26 and 82 centimeters) or higher by the end of the century.
- Hurricanes and other storms are likely to become stronger. ...
- Less freshwater will be available, since glaciers store about three-quarters of the world's freshwater.
Is there proof that global warming exists?
There are many lines of independent empirical evidence for global warming, from accelerated ice loss from the Arctic to Antarctica to the poleward migration of plant and animal species across the globe.
What are the symptoms of global warming?
Global warming may increase risk of infectious diseases Climate change is likely to increase the number of viral transmissions across species, posing further risk to other animals and humans ...

What are the main indicators of global warming?
Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events – like heavy rainstorms and record high temperatures – are already happening.

What are the 11 effects of global warming?
Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few. Some of Australia's great natural icons, such as the Great Barrier Reef, are already threatened.

What are the causes of global warming Class 7?
Massive deforestation, burning of fossil fuels, industrial emissions, etc. have resulted to an increase in greenhouse gases around earth's atmosphere. The greenhouse-gases trap Sun rays in the earth's atmosphere causing the temperature to rise resulting in what is known as global warming.
What are the signs of global warming What are consequences?
We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.

What are the 3 main causes of global warming?
Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth's temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
What is global warming short answer?
Global warming is the long-term heating of Earth's surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. This term is not interchangeable with the term "climate change."
