Door mens veroorzaakte klimaatveran

Door mens veroorzaakte klimaatverandering begon rond 1830
Mensen zorgen er al ruim 180 jaar voor dat de aarde langzaam opwarmt, zo blijkt uit een nieuwe studie.
De eerste tekenen van het door de mens veroorzaakte broeikaseffect waren al merkbaar aan het begin van de industriële revolutie.

Veel oceanen begonnen rond 1830 op te warmen door de uitstoot van broeikasgassen.

Dat meldt een internationaal team van onderzoekers in het wetenschappelijk tijdschrift Nature.

Gletsjers
De wetenschappers onderzochten de klimaatgeschiedenis van verschillende gebieden op aarde door gletsjers, groeiringen van bomen en eeuwenoud koraal te bestuderen. Ze slaagden er uiteindelijk in om het klimaat van de afgelopen vijfhonderd jaar te reconstrueren met behulp van de verzamelde gegevens en een computermodel.

Uit het onderzoek blijkt dat menselijke activiteit rond het jaar 1830 voor het eerst in verband kan worden gebracht met klimaatverandering. "De resultaten zijn duidelijk", aldus hoofdonderzoekster Nerilie Abram op nieuwssite Phys.org. "De opwarming van het klimaat waarvan we vandaag de dag getuige zijn, begon ongeveer 180 jaar geleden."

Verrassend
Met name oceaangebieden in de tropen en nabij de Noord- en Zuidpool begonnen in de negentiende eeuw al op te warmen.

Abram is verbaasd over haar bevindingen, aangezien de wereldwijde industrialisatie rond 1830 nog geen grootste vormen had aangenomen. "De toename van broeikasgassen in deze periode was klein in vergelijking met de snelle veranderingen van nu", aldus Abram in de Britse krant The Guardian. "Het is verrassend om te zien dat het klimaat al zo sterk reageerde."

Hoop
De ontdekking biedt volgens haar echter ook hoop. Mogelijk zal de opwarming van de aarde ook snel afzwakken wanneer het broeikaseffect wordt beperkt.

"Als we iets kunnen doen om de uitstoot van broeikasgassen te vertragen of zelfs terugdringen, zullen sommige onderdelen van het klimaatsysteem mogelijk ook snel reageren en ons daarvoor terugbetalen", aldus Abram.

people worry there for over 180 years that the earth is warming up slowly, says a new study.
The first signs of global warming caused by humans were already noticeable at the beginning of the industrial revolution.

Many oceans began to warm up around 1830 by the emission of greenhouse gases.

study, the scientists examined the climate history of different areas on earth by glaciers, growth rings of trees and ancient coral. She finally managed to reconstruct the climate of the past five hundred years using the collected data and a computer.

The research shows that human activity for the first time can be associated with climate change around the year 1830. "The results are clear," said lead researcher Nerilie Abram news Phys.org. "The warming of the climate which are the day are witnessing today, some 180 years ago we saw."

Surprisingly,
particularly ocean areas in the tropics and near the North and South Poles already started to warm up in the nineteenth century.

Abram surprised her findings, since the global industrialization had no major form yet adopted around 1830. "The increase in greenhouse gases in this period was small in comparison to the rapid changes of today," said Abram in the British newspaper The Guardian. "It is surprising to see that the climate already reacted so strongly."

Hope
The discovery provides in its hope. Possible will weaken the global warming too quickly when the greenhouse effect is limited.

"If we can do something to slow down or even reduce greenhouse gas emissions, some parts will of the climate system may also respond quickly and reimburse us for that," said Abram.
