Agenda:what is climate change?Is climate change real ?Causes of climate changeEffect of climate change in sea levelEffect of climate change in EgyptSeawater intrusion
What is climate change?Climate change variations in climate on many different time scales from decades to millions of years of human or natural influences.
4Is the climate change real? There is argument about the climate change
5Is the climate change real? 1st opinion that there is climate change
6Is the climate change real? 2st opinion that there is no climate change
7Global Temperatures Graph
Our Opinion
8What causes climate change? 1st Natural causes:
Volcano Eruption
Ocean Current
9What causes climate change? Earth Orbital change & Solar Variation
10What causes climate change? 2st Human causes: Release of Green House GasesGlobal WormingClimate ChangeHuman Activities
11Sea Level Rise
12
Sea level rise
13Higher temperatures are expected to further raise sea level by expanding ocean water, melting mountain glaciers and small ice caps, and causing portions of Greenland and the Antarctic ice sheets to melt.
Global mean sea-level has been rising at rates ranging between 10 and 20 mm/yr over the last century
And it is expected to rise between 3080 cm by 2100.
14
15Effects of rising in sea levelIncrease in coastal erosion and sea water intrusion.Salt water intrusionIncreased wave conditions at coastal structures and beaches that increases load on structure and erosion at beaches.Modified sediment budget (Morphological changes).Many Areas Of The Coasts Will Be Submerged.Heavy flooding, high tides.

18What about Egypt?
19How to protect the coasts from the SLR?
20Seawater Intrusion
21
22How to protect Groundwater from intrusion?Reduce the uses of GW on coastal reasonrelocate the well positions Put subsurface barriers to make artificial walls against seawater intrusionRecharge the groundwater naturally Recharge groundwater artificially Take water from seawater to decrease its level and use it like in cooling the machines
