How Global Warming has
affected Germany
By Jes Baldeweg-Rau
What is Global Warming?
• Global warming refers to the rising average temperature of Earth's
atmosphere and oceans and its projected continuation.
• In the last 100 years, Earth's average surface temperature increased by
about 0.8 °C (1.4 °F) with about two thirds of the increase occurring
over just the last three decades.
• Because the Earth has been gradually becoming warmer for so long
there is debate about the validity of global warming and its existence.
• Scientists are more than 90% certain most of it is caused by increasing
concentrations of greenhouse gases produced by human activities such
as deforestation and burning fossil fuels.
• Effects of the warming include more frequent occurrence of extreme
weather events such as heat waves, droughts and heavy rainfall.
Global Warming in Germany
• Even moderate climate change and limited land use changes
could have an adverse impact on flora in Germany.
• Saarland, Rhineland Palatinate and Hesse and the lowland
plains of Brandenburg, Saxony-Anhalt and Saxony could
suffer particularly high species losses.
• Many plant species could lose their niches in habitats such as
mountains or moors.
• German agricultural sector however could gain from global
warming. Plants at which are more labor intensive are
supposedly benefiting from the increased temperature.
• Some of the plants at risk in Germany due to global warming
are the Picea abies and the Caltha palustris.

Global Warming's Effect on
German Alcohol Production
• Climate change has had a marked impact on global weather patterns
and led to growing concerns among wineries about their multibillion
dollar industry.
• Fewer frosts due to warmer weather are causing the grapes to ripen
too early, which means the varietal flavors do not have the chance to
develop.
• Within this century, global warming is likely to force vintners to tear
up their grape crops and switch to grapes that grow in warmer
climates.
• The 2006 European heat wave brought an uncharacteristically hot and
stormy summer, which greatly damaged Germany's vital barley crop.
• It is law in Germany for brewers to only use hops, barley, water, and
yeast in their beers. If barley is not available due to rising
temperatures, it would be illegal to make a beer using any other
substitute.
