How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Global Warming and Its Effects
Climate change is affecting worldwide temperatures, including in Itatiaia. It has massive impacts on both local and global levels:
- Global Temperature Rise: The average global land and sea temperatures have risen by about 1.2°C since pre-industrial times.
-
Local Impacts: Most regions of the world are witnessing warmer winters with fewer frost and snowfall days. The global frequency and severity of heatwaves have increased. For example, Europe's summers of 2018, 2019, and 2020 all broke records. Summers are also becoming drier; however, during winter, inland regions have experienced increased rainfall. This has caused elevated river levels and more cases of flooding.
Many countries are experiencing earlier springs and later autumns. This is why some bird species have shifted their migration dates.
