Document Summary
Projections: based on one particular model. Prediction: statement regarding future based on projections. Global mean air temperature: will continue to rise of greenhouse gas emissions also rise, significant anthropogenic impact. Climate in the news: 2015 was the warmest year on record, most of globe experienced record warmth, exception: north atlantic (complex ocean heating) Changes in temperature: high confidence that globally averaged changes over land will exceed changes over the ocean, in the absence of a strong reduction in the atlantic meridional. Overturning, the arctic region is projected to warm the most: the polar amplification is not found in the antarctic regions. What are the average conditions at the northern edge of the. Dry: over most of the mid latitude land masses and over wet tropical regions, extreme precipitation events will very likely be more intense and more frequent in a warmer world.
