WASHINGTON -- Scientists from around the world issued a new study Wednesday with even more evidence of global warming.

The last decade was the warmest on record, according to the annual “State of the Climate Report,” released by the National Oceanic and Atmospheric Administration.

More than 300 scientists from 160 research groups in 48 countries each contributed to the findings. The report is published annually as a supplement to the Bulletin of the American Meteorological Society.

“The records come from many institutions worldwide. They use data collected from diverse sources, including satellites, weather balloons, weather stations, ships, buoys and field surveys. These independently produced lines of evidence all point to the same conclusion: our planet is warming,” NOAA spokesperson Jane Lubchenco, Ph.D. said.

The analysis focused on 10 measures of climate ranging from the well-known air temperature to changes in glaciers, humidity, sea level and ocean temperatures.

The report states seven indicators are rising, while three are declining.

Rising indicators include:
• Air temperature over land
• Sea-surface temperature
• Air temperature over oceans
• Sea level
• Ocean heat
• Humidity
• Tropospheric temperature in the “active-weather” layer of the atmosphere closest to the Earth’s surface

Declining indicators include:
• Arctic sea ice
• Glaciers
• Spring snow cover in the Northern hemisphere

Officials say that while natural patterns like El Niño and La Niña reflect year-to-year changes, global warming is revealed through changes over many decades.

According to trends, each of the three decades (1980s, 1990s, 2000) have been increasingly and significantly warmer than the last.

The report came just one day after President Barack Obama renewed his call for climate legislation.
