What are greenhouse gases?
Humans emit more greenhouse gases than is natural. The gases mean that less heat escapes through the atmosphere. The greenhouse effect is reinforced.
Although there are many greenhouse gases, there is a lot of talk about carbon dioxide, CO₂. It is the greenhouse gas that contributes the most to global warming. It is also the greenhouse gas that remains in the atmosphere the longest. Even if we sharply cut CO₂ emissions, the CO₂ level in the atmosphere will continue to rise.

Hva er klimagasser? https://perma.cc/D77X-RWJU
Menneskene slipper ut mer klimagasser enn det som er naturlig. Gassene gjør at mindre varme slipper ut gjennom atmosfæren. Drivhuseffekten blir forsterket.
Selv om det finnes mange klimagasser, snakkes det mye om karbondioksid, CO₂. Det er den klimagassen som bidrar mest til den globale oppvarmingen. Det er også klimagassen som blir værende lengst i atmosfæren. Selv om vi kutter kraftig i CO₂-utslipp, vil CO₂-nivået i atmosfæren fortsette å stige.

Gjør det noe at det blir varmere?
Det høres ikke så mye ut at jorda blir én eller to grader varmere, men husk at dette er et gjennomsnitt.
Forskerne advarer mot de ekstremt varme dagene, som i fremtiden kan bli mye varmere enn de varme dagene vi opplever i dag. Klimaendringene vil også gi andre typer ekstremvær, som flom, tørke og skred.

Does it matter if it gets warmer?
It doesn't sound like much that the earth is getting one or two degrees warmer, but remember that this is an average.
The researchers warn against the extremely hot days, which in the future could be much hotter than the hot days we experience today. Climate change will also cause other types of extreme weather, such as floods, droughts and landslides.

Alle land som er med i Parisavtalen, skal melde inn stadig strengere mål for å kutte egne utslipp.

All countries that are part of the Paris Agreement must submit increasingly strict targets to cut their own emissions.

YES 🇮🇱 ISRAEL AND 🇵🇸 PALESTINE, YOU TOO!!!!

The highest CO2 emissions from tourism was calculated to be from aviation, with 71% of total CO2 travel emissions. This is followed by waterborne navigation (ferries and cruises; 21%) and road transport (private cars; 8%).

Aviation is the largest contributing sub-sector, mainly owing to the large number of travellers and the long distances travelled. The highest emissions factors per passenger kilometre were found for cruise ships and ferries transporting cars in addition to passengers.

Total CO2 emissions are dominated by Norwegians travelling for HOLIDAYS!!!!! (= NOT BUSINESS!), which contributes 47% of total emissions. The largest share of Norwegian travel emissions is from international aviation (2 286 kt CO2 ) to warm destinations such as Spain, Greece, Thailand and Turkey.

International tourists who visit Norway make for 3 273 kt CO2, of which 2 220 kt is from aviation and 949 kt from waterborne navigation.

The tourist market with highest emissions is Germany with 441 kt CO2 of which 15%, 48% and 37% come from aviation, cruises and ferries, respectively. Passengers from USA cause the second highest emissions, mainly from aviation (349 kt CO2) and cruise ships (56 kt CO2).

Of the total tourist emissions, holiday travel contributes 78%.

In 2020, restrictions were put on travel due to the COVID-19 pandemic, leading to a reduction in mobility. As a consequence, CO2 emissions experienced a massive reduction of 60%, which was sustained from late March to at least the end the year.

Aviation and cruise ship emissions had the largest emission decreases, whereas road transport emissions in July 2020 were at the same level or even higher than in pre- COVID years.

Cruise ships have the highest emission factor, but the emission factor from ferries is of similar magnitude when one also takes into account the transport of cars.

Emissions range from 93 to 615 kg of CO2 per passenger-day, or from 199 to 1314 g CO2 per passenger-km, depending on the size, the age and the ship’s capacity configuration
