The above plot is average annual temperature for the selected station. Switch stations by using the map below. In grey is historical data from the Global Historical Climatology Network (GHCN). The post-1900 trend is in black. GHCN includes approximately 6,000 temperature stations across the globe, and is the primary source for temperature data for global temperature records. Records in this GHCN database date back to as early as 1700. There are some gaps in the GHCN data, and when this occurs, the legend will say "N/A."
In red and orange are the projections from global climate models under two IPCC greenhouse gas emissions scenarios: high (red, A1B) and low (orange, B1). The result is an average of many global climate simulations, which can be found here. The low emissions scenario projects a 1.8°C global rise in temperature through 2100, while the high emissions scenario projects a 2.8°C global rise in average temperature through 2100. Note: The high emissions scenario is not the highest in the IPCC scenarios. The highest scenario is A1F1, which projects up to 6.4°C warming, globally. Our current emissions are on a pace greater than A1B, and close to A1F1.

About Local Climate Change
People all across the globe are feeling the impacts of climate change in their back yards. The Local Climate Change product is a way to see changes that are happening in your region. Use the tabs to browse historical and projected changes in temperature, precipitation, and snow. We plan add more data later this year, including drought, growing season, sea level rise, and extreme weather.
