What are the signs of global warming?

Answer 1

• climate change, extreme weather events.
• the melting of the polar ice caps
• sea level rising
• Pacific Island countries under water
• Glaciers retreating
• rising temperatures
• ski resorts closed
• animal species extinct
• climate refugees moving countries
• people in poor countries dying of starvation

• melting of polar ice caps

• rise in temperature

• floods

Answer 2

• Rising temperatures
• Floods
• Famine
• Climate change,
• extreme weather events.
• the melting of the polar ice caps
• sea level rising
• Pacific Island countries under water
• Glaciers retreating

Answer 3

• Climate change, extreme weather events, floods, droughts, storms, leading to crop failures and famine.
• Melting glaciers and ice caps leading to rising sea levels threatening low lying countries and coastal areas - desperate climate migrants.

Answer 4

Global warming is a very gradual process and is to a considerable degree masked by short term climate fluctuations, so you should not expect to look outside and see regular, observable changes that result from global warming.

To scientists, an observable indication of global warming is the gradual rise in average global temperatures since recordings first began in 1850. To a more casual observer, a more graphic indication of global warming is in the recent climate records: globally the warmest years on record have been 1998, 2005 and then 2010; the ten warmest years since 1850 have now all occurred since 1998; the past decade was the warmest since instrumental measurement began. Some plants begin their spring growth a little sooner or flower a little earlier; to scientists this is another observable indication of global warming.

Answer 5

Data available from monitoring networks run by reputable national, international and independent scientific organizations indicates we've pretty much seen all of the "early warning" events:

• increased ocean temperature
• increase in ocean acidity
• rising ocean levels impacting Pacific islands
• average temperature increases
• melting of ice deposits at the poles and in glaciers
• movement of plant and animal species further north
• permafrost melting
• changes in rainfall patterns (floods and droughts)
• increased severe weather events

Answer 6

Global warming is a small but measurable increase in the mean average temperature of the planet over time. It is indicated by several lines of evidence including tree rings, ice cores, corals, lake sediments, cave formations, ocean sediments, and of course human records. The consequences of global warming may be considered 'signs' as well.

One of the most predominant and strikingly visible signs of global warming is glacial and ice sheet melting, coinciding with a rising sea level. Other signs include changing weather patterns, changes in behavior of migrating animals, earlier leafing of deciduous foliage, and warm water adaptations in traditionally cold water oceanic populations.

Answer 7

some signs of global warming is the changing of rain patterns, sea level is rising, and snow/ice is melting soon in the spring. 
