Analyses of climate measurement series from Rwandan weather stations revealed that the division into the four formerly described Rwandan climate zones is not correct any more. This could be shown in a more detailed analysis based on currently available data. In the course of discussions held with the Service Meteo Rwanda it emerged that the climate charts used in Rwandan atlases and school books are based on data covering the period from 1931 to 1960. Fortunately, since then a mass of new data have been collected, which, however, until now have only been evaluated in isolated instances for a specific local as needed. This led to the initiation of the ReCCiR project. The project’s aim was to conduct a regional climatic analysis covering all of Rwanda and visualizing it on new maps.
This paper gives an historic perspective on 10 critical phases and actions in advancing an understanding of climate change and taking appropriate domestic and international action. Credit goes to atmospheric scientists for their committed efforts to understand, model and measure the impacts of climate change. Today, greenhouse gases are at a record level and little doubt remains that greenhouse gases (GHG) warm the atmosphere and that human-made climate change is real. Recognizing the urgency of responding to climate change, the 2013 US Climate Action Plan aims to cut carbon emissions and prepare to deal effectively with the economic, social, and environmental impacts of climate change. Many US states, Tribes, and local communities have also begun to take action to reduce GHG emissions and adapt to the impact of climate change, especially on disadvantaged communities. While recognition of the urgency of action on climate change is growing in government and in large parts of the business and financial sector, it has taken over 40 years to get to this point. While an understanding of the reality and impact of climate change has grown, significant efforts to reduce the concentration of greenhouse gases in the atmosphere and stabilize global warming have not occurred. The problem that society faces is not the absence of scientific knowledge, but rather the need to reduce GHG emissions and create resilient and adaptive responses to climate change. This paper concludes that future successes will need more effective collaboration between government, business, and society to address climate change and greater public understanding of the impacts of climate change on human health and economic well-being.

The meteorological series have been chosen because they were meteorological
observatories operating continuously from the beginning of 1900 until 2011. As
the first step an historical research over each station has been carried out.
In this way, the potential breaks, in the series, either due to changes of
locations or instruments, have been determined and the missing values have been
recovered. On the precipitation daily series a quality control have been
effectuated and by metadata identification it was possible to assess the
homogeneity of the meteorological series. In this way we have obtained the
complete and correct series on which trends have been computed. In order to
better understand the consequences of climate variations on our environment and
society, we have calculated the climate indices proposed by “CCL/CLIVAR Working
Group on Climate Change Detection” (dry and wet days, rainy days, intensity of
precipitation…) over the time. The values of precipitation have also allowed beginning
the climatic analysis with the aim at defining the principle local peculiarity
