• airearen tenperatura gainazaletik gertu(troposphere)
• Specific humidity
• Ocean heat content
• Sea level
• Sea-surface temperature
• Temperature over the oceans
• Temperature over the land

Observations show that these 7 indicators are, in fact, increasing. The following three indicators would be expected to decrease in a warming world. These are:

• Snow cover (March-April, Northern Hemisphere)
• Glaciers (glacier mass balance)
• Sea-ice (September Arctic sea-ice extent)

Observations show that these 3 indicators are, in fact, decreasing.

From page 2 of the cited public-domain source: "A comprehensive review of key climate indicators confirms the world is warming and the past decade was the warmest on record. More than 300 scientists from 48 countries analyzed data on 37 climate indicators, including sea ice, glaciers and air temperatures. A more detailed review of 10 of these indicators, selected because they are clearly and directly related to surface temperatures, all tell the same story: global warming is undeniable. For example, the surface air temperature record is compiled from weather stations around the world, and analyses of those temperatures from four different institutions show an unmistakable upward trend across the globe. But even without those measurements, nine other major indicators of climate change agree: the earth is growing warmer and has been for more than three decades.

A warmer climate means higher sea level, humidity and temperatures in the air and ocean. A warmer climate also means less snow cover, melting Arctic sea ice and shrinking glaciers."
