The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases.
There is a broad scientific consensus that climate change is occurring, and that human activities are the primary driver.
"Attribution" of causes of climate change is the process of establishing the most likely causes for the detected change with some defined level of confidence.
The graph above shows the average of a set of temperature simulations for the 20th century (black line), followed by projected temperatures for the 21st century based on three greenhouse gas emissions scenarios (colored lines).
The SRES scenarios were "baseline" (or "reference") scenarios, which means that they do not take into account any current or future measures to limit GHG emissions (e.g., the UNFCCC's Kyoto Protocol and the Cancún agreements).

In the IPCC's Fifth Assessment Report released in 2014, SRES projections were superseded by Representative Concentration Pathways (RCPs) models.
Examples of climate change include increases in global surface temperature (global warming), changes in rainfall patterns, and changes in the frequency of extreme weather events.
Changes in climate may be due to natural causes, e.g., changes in the sun's output, or due to human activities, e.g., changing the composition of the atmosphere.
A map that shows ice concentration on 16 September 2012, along with the extent of the previous record low (yellow line) and the mid-September median extent (black line) setting a new record low that was 18 percent smaller than the previous record and nearly 50 percent smaller than the long-term (1979–2000) average.
