climate change

1. Water and climate
 How does climate change affect ''our waters''

2. Climate scientists have been saying all along that one of
the primary effects of climate change is the disruption of
the water cycle. Since so much of everyday life and
planning is determined by hydrological systems, it's
important to understand the impact that climate change is
having on water.

3. Climate Change and Water are
Closely Linked
Climate change has the potential to tip out of balance the
relatively stable climate in which civilization has been built
and jeopardize the security of water, food and energy
systems. Over time, the effects of global warming due to
the human-generated buildup of greenhouse gases in the
atmosphere have become more evident.

4. Climate Change and droughts
Scientists believe that droughts are mainly linked with
climate change. A major factor of climate change that
causes droughts, is that high temperatures lead to
extravagant water evaporation and also increase
evaporation in plant soils.

5. Climate change and extreme
precipitation
Several studies concluded that climate change created
conditions like evaporation in plant soils, which made
torrential rainfall more likely. Higher average temperatures
and warmer air that can hold more water may result in long
dry periods intermixed with brief but heavy precipitation and
possible flooding.

6. Climate change and glaciers
As global temperatures elevate, mountain glaciers and
snowpack are melting at an unprecedented rate. Many
mountain glaciers are in retreat and in danger of
disappearing. Glaciers can not be restored if they melt, so
areas that depend on them have to find new fresh water
sources. Also glaciers’ melting is expanding the volume of
oceans.

7. Climate change and algal bloom
Climate change has warmed up water bodies and caused
harmful algal blooms to occur more often and be more
intense in rivers, lakes and oceans. These blooms can
damage aquatic life and can produce toxins that are
dangerous for humans and other animals to touch or drink.
These events can hurt the economy and human health by
polluting drinking water.
