Klimawandel, Treibhauseffekt und globale Erwärmung in 3 Minuten erklärt
Summary
TLDRThe script discusses the impact of climate change, the greenhouse effect, and global warming. It explains that climate change is a long-term phenomenon, unlike weather, which is short-term. Over the last century, the global average temperature has risen by about one degree Celsius, a significant increase considering the current warming is faster than any natural warming phase in the last 65 million years. The script highlights the greenhouse effect, a natural process that keeps Earth warm, but which has been exacerbated by industrial activities and the burning of fossil fuels, leading to an increase in greenhouse gases like carbon dioxide and methane. The consequences are already being felt, with more frequent extreme weather events and warmer winters, and long-term effects include melting polar ice caps and rising sea levels. The script calls for action to address these threats to ecosystems and biodiversity, potentially leading to the extinction of one-third of all species.
Takeaways
- 🌍 The climate is changing and can be felt and heard about in the media, unlike weather which refers to short-term conditions at a specific location.
- 📈 Over the last century, the global average temperature has risen by about one degree Celsius, indicating a faster warming phase than any known natural warming phases in the last 65 million years.
- 🔬 The majority of scientists agree that the current global warming is caused by human activities.
- 🌡️ The greenhouse effect is a significant cause of global warming, where the Earth's atmosphere lets sunlight in and traps heat radiated back by greenhouse gases.
- ☀️ Without the natural greenhouse effect, the average global temperature would be -18 degrees Celsius instead of the pleasant 15 degrees Celsius.

Q & A
What is the difference between climate and weather as described in the script?
-The script explains that climate refers to the weather conditions over a long period of time and in a larger region, while weather refers to short-term conditions like sunshine or rain at a specific location.
How much has the global average temperature increased in the last century according to the script?
-The script states that the global average temperature has risen by approximately one degree Celsius in the last century.
What is the current rate of global warming compared to natural warming phases in the past?
-The script mentions that the current warming is happening faster than any known natural warming phases in the last 65 million years.
What is the greenhouse effect and how does it contribute to global warming?
-The greenhouse effect is a natural process where the Earth's atmosphere allows sunlight to pass through but traps heat by absorbing reflected radiation and emitting it back as longer wavelength radiation. This effect is essential for maintaining a warm climate on Earth. However, the increase in greenhouse gases due to human activities has intensified this effect, leading to global warming.
What are the main human activities that have increased the concentration of greenhouse gases?
-The script identifies industrial processes and the burning of fossil fuels like coal and oil as the main activities contributing to the increase in greenhouse gases. Additionally, deforestation is also a significant factor, as it reduces the capacity of plants to absorb CO2.
What are the consequences of the increased greenhouse effect mentioned in the script?
-The script mentions several consequences, including more frequent weather extremes, warmer winters, melting of polar ice caps leading to rising sea levels, and threats to many plant and animal species, with the potential for one-third of species to become extinct.
What is the role of CO2 and how does it contribute to the greenhouse effect?
-CO2, or carbon dioxide, is a greenhouse gas that plays a significant role in the greenhouse effect by trapping heat in the Earth's atmosphere. The script points out that the use of fossil fuels in industry and transportation, as well as deforestation, have led to an increase in atmospheric CO2 levels.
How does the script describe the impact of deforestation on global warming?
-The script explains that deforestation contributes to global warming by reducing the number of plants available to absorb CO2 and convert it into oxygen. It also mentions that the Amazon region, for example, has stored as much CO2 as the world produces in 15 years.
What is the significance of the 15 degrees Celsius mentioned in the script?
-The script states that without the natural greenhouse effect, the global average temperature would be minus 18 degrees Celsius. The 15 degrees Celsius is the difference the greenhouse effect makes, making the Earth warm enough to sustain life.
What is the script's call to action for the audience?
-The script urges the audience to become active in addressing climate change, emphasizing that it is a concern for the global community and for every individual.
What is the script's reference to 'Part 2' imply about the content?
-The mention of 'Part 2' suggests that the script is part of a larger discussion or series, and that further details or actions related to the topic of climate change will be covered in the subsequent part.

ex-playmate erklärt klimawandel
treibhauseffekt und globale erwärmung
unser klima verändert sich das spüren
wir und hören es auch immer wieder in
den medien
im gegensatz zum wetter was einen
kurzfristigen zustand wie sonnenschein
oder regen an einem bestimmten ort
bezeichnet betrachtet man beim klima das
wetter über einen längeren zeitraum und
in einer größeren region im letzten
jahrhundert hat sich das klima auf der
welt verändert die globale
durchschnittstemperatur ist um ungefähr
ein grad gestiegen
gar nicht so viel könnte man meinen aber
die aktuelle erwärmung verläuft
schneller als alle bekannten und
natürlichen erwärmung phasen in den
letzten 65 millionen jahren
mittlerweile sind sich die meisten
wissenschaftler deshalb einig die
aktuelle erderwärmung ist von menschen
verursachen eine wichtige ursache für
die globale erwärmung ist der sogenannte
treibhauseffekt wie bei einem
gewächshaus lässt die erdatmosphäre
sonnenstrahlen größtenteils ungehindert
zu uns durch die strahlen werden von der
erde reflektiert um die sogenannten
treibhausgase in der atmosphäre nehmen
die strahlung weitgehend auf erwärmen
sich und schicken uns länger wellige
strahlung zurück das ist ein ganz
natürlicher prozess durch dem es auf der
erde angenehm warm ist im globalen
durchschnitt 15 grad
ohne diesen natürlichen treibhauseffekt
wäre es im schnitt minus 18 grad kalt
seit beginn des industriezeitalters ist
die konzentration der treibhausgase
jedoch stark gestiegen
denn viele industrielle prozesse
erzeugen treibhausgase wie
kohlenstoffdioxid kurz co2 oder methan
und vereinfacht kann man sagen je mehr
treibhausgase in der atmosphäre desto
mehr rückstrahlung und umso wärmer wird
es auf der erde verursacht haben wir den
anstieg der treibhausgase zum beispiel
dadurch dass wir in der industrie oder
im autoverkehr fossile brennstoffe wie
kohle oder erdöl verwenden und durch die
abholzung von wäldern
denn pflanzen nehmen co2 auf und wandeln
es in sauerstoff um die amazonasregion
zum beispiel hat so viel co2 gespeichert
wie die ganze welt in 15 jahren
produziert die folgen manche spüren wir
heute schon zum beispiel häufigere
wetter extreme oder wärmere winter
langfristig schmilzt durch wärmeres
klima das eis an den polkappen
dadurch steigt der meeresspiegel viele
regionen pflanzen und auch tiere sind
von der erderwärmung bedroht
im schlimmsten fall könnte jede dritte
art aussterben
höchste zeit aktiv zu werden für die
weltgemeinschaft aber auch für jeden
einzelnen
und genau darum geht es in teil 2
