Rigorous analysis indicated the clear evidence of climate change at the global level because the temperature has risen to 0.8 Celsius in a period of 150 years. The evidence is also observed at the Rwanda scale.
Key evidence of climate change at the global level
- The temperature has risen to 0.8 Celsius in a period of 150 years
- Global sea levels rose between 10 and 20cm (8ins) in the last century
- The number of weather-related disasters has increased by a factor of five over 50 years
- Since the 1800s, the oceans have become about 40% more acid, affecting marine life
Evidence of Climate Change in Rwanda
- Rwanda is experiencing severe droughts, especially in the east and southeast. These changes are related to global warming. Climate Change effects have been experienced in Rwanda:
- An analysis of the temperature measurements taken in Kanombe and Kamembe between 1971 and 2009, shows that the temperature increased by 1.2 Celsius in Rwanda, while the average temperature increase at the global level is 0.8 Celsius in the period of 150 years
- Rwanda is experiencing an increasing temperature, where during the daytime; sometimes the temperature is more than 30 degrees Celsius.
- During the rainy season (March, April, and May) the sunny days have been increased
- Rainy seasons are becoming shorter and more intense, especially in the northern and western provinces. Which in turn affects agricultural production;
- Sometimes one rainy day can even have approximately the average amount of rainfall per month. This causes floods, landslides, etc
- The number of days of rainfall per year decreased. Estimates at Kanombe station indicated that between 1971 and 2009, the number of days of rainfall per year fell from 148 to 124 days
