Climate change Flashcards
Some people class climate change warnings as things like
Global warming
Orbital changes are changing the earths distance from the Sun. Three distinct cycles are:
- eccentricity
- axial tilt
- precession
Solar activity varies
with
The number of sunspots and high energy solar flares
Volcanic ash can block out the Sun reducing
Temperatures on the Earth. This is short-term impact
Global temperatures have been
Global temperatures have been cooling gradually over 5.5 million years, but increasing in recent decades
Climate change evidence is
Melting glaciers, rising sea levels, changing seasons and direct temperatures
Climate change is having a significant effect on
Climate change is having a significant effect on Global ecosystems and on peoples lives
The greenhouse effect keeps the Earth
Naturally warm enough to support life
The enhanced greenhouse effect is changing
Climates, weather patterns and sea
The greenhouse effect is increased by
Human activities
Alternative energy sources represent
Sustainable alternatives to fossil feels
Carbon capture is
Filtering and storing carbon under the ground
International agreements are being establish for a
Sustainable future
Climate change creates global impacts like
Reducing crops and water yields, more heat related illnesses, more threats of flooding, changing ecosystems, more extreme weather, stronger tropical storms and desertification
Agriculture adaptation means
Farmers adapt by doing things like coping with heat and floods
