Climates in France

The 5 different climates are the following: The oceanic climate: mild and humid The modified oceanic climate : The oceanic climate is modified by continental influences The continental climate: hot in summer, cold in winter Mediterranean climate : high temperatures in the summer, warm winters with lots of rain ( floodrisk) The mountain climate : long and cold winters

The 5 different climates • Oceanic climate • Modified oceanic • • • climate Continental climate Mediterranean climate Mountain climate

The modified oceanic climate Our region is situated here on the map. We have got an oceanic climate This means that the climate is warmer in the summer and colder in the winter compared to an oceanic climate.

Changes in the world temperature Climate changes have always existed on our planet. Look at the temperature line on this diagram. The past is on the right, the present is on the left. These changes have taken place over a long period of time. The scale of this diagram is in millions of years.

The climate changes of past

Climate changes in the past. This diagram shows the temperatures in France from 1950 to nowadays. You can see that the temperatures have increased a lot in such a short lapse of time.

The evolution of temperatures in France. Climate changes in France have always existed because of the Milankovitch cycles and volcanic eruptions, but today's changes are more brutal due to the greenhouse gases emitted by man

The climatic changes in the past A hundred million years ago, the quantity of CO 2 was 3 to 5 times higher than in 1750 (before the industrail revolution) and the temperatures were 10°C higher. 67 Million years ago there was a brutal drop in temperatures, probably caused by dust in the atmosphere (volcanic activity or fall of meteorites) that darkened the sky. 18, 000 years ago, the last ice age. Temperatures on Earth were approximately 4°C lower than those today.

The main origin of the global warming Between 1920 and 1941, the Serbian astronomer Milutin Milankovitch demonstrated that the average temperature of the Earth varies according to a cycle. This cycle of glaciation finds its origin for the periods of 100 000 years, of 40 000 years and of 20 000 characteristic years respectively variations of the eccentricity of the ground orbit, the slope of the axis of rotation of the Earth ( the nutation) and its pretransfer (or rotation of this axis). http: //menaceclimatique. free. fr/anim_milankovitch. php

We can see that the average world temperatures have risen by 0. 6 ° C (degrees celsius) during the 20 th century, where as, in France, they have risen by 0. 9°C. Before the end of the century the temperatures may rise between 1. 4°C and 5. 8°C. In France this increase will undoubtedly be even higher.

The futur climate Increase of the average temperatures on the world Increase of the average level of the oceans Increase of the average temperatures in France In XXth centuries In XXI centuries +0. 6°C +1. 4°C to 5. 8°C +10 to 20 cm +9 to 88 cm +0. 9°C

Future climate During the 21 st century scientists expect an average land temperature increase of 1. 4°C to 5. 8°C and an average increase in sea level of 9 to 88 cm.
