Why Lake Geneva’s warming waters are worrying scientists

Record-high temperatures measured at Switzerland’s Lake Geneva have sparked concerns about its future.

For years, the lake, known locally as Lac Léman and shared between Switzerland and France, has been falling victim of global warming, in pretty much the same way as melting glaciers. 

Its water had reached an average temperature of 13.6C in 2022, according to a recent report by the International Commission for the Protection of the Waters of Lake Geneva (CIPEL). 

While this may be welcome news for swimmers, such a drastic temperature change is damaging the lake’s delicate natural ecosystem.

That’s because warm water on top and cooler water trapped below creates less oxygen, which, in turn, can kill fish and other marine organisms that can no longer breathe underneath the surface.

In view of this alarming deterioration, CIPEL is committed to strengthening “the implementation of effective conservation measures for Lake Geneva,” the organisation said.

Action is needed because “in a context of climate change, Lake Geneva is an invaluable strategic resource, and it is essential to guarantee its good quality,” CIPEL  pointed out.

The findings of its report are important, the organisation added, because they “provide a crucial basis for policy makers, scientists, and the local community in the protection of our precious lake ecosystem.”

  1. 13.6 C must be a typo because that’s not very warm for the Swiss lakes (about 57 F.). Are you sure it wasn’t 23.6 C.?

Could Geneva be first Swiss canton to grant foreign residents more voting rights?

Voters in the country’s most "international" canton Geneva will soon have their say on whether non-Swiss citizens living in their midst should have more political rights.

Could Geneva be first Swiss canton to grant foreign residents more voting rights?

Foreigners are not allowed to vote on national level anywhere in Switzerland.

Though there had been attempts in the past to change this rule, the latest such move was turned down by legislators in 2022.

However, five cantons are permitting foreign residents to cast their votes in local referendums and elections: Geneva, Vaud, Fribourg, Neuchâtel, and Jura. Conditions vary from one canton to another, but in all cases a certain length of stay and a residence permit are required.

(In Zurich, a similar move was rejected in 2023).

Of the five cantons, only Neuchâtel and Jura authorise foreign residents to vote on cantonal level in addition to communal one; in the others, they can cast municipal ballots only. 

Additionally, three other cantons have similar laws on their books, but they this legislation remains mostly inactive.

Basel-City, Graubünden, and Appenzell-Ausserrhoden have authorised their communes to introduce the right to vote, the right to elect, and the right to be elected for their non-Swiss residents. 

However, only few of the communes in these cantons have actually introduced these measures.

Wait…Geneva’s foreigners already have the right to vote?

Yes, they have had this right since 2005, but only on municipal level.

However, this could change on June 9th, when Geneva residents will go to the polls to weigh in on an initiative launched by the trade unions and political left, calling for foreigners who have lived in the canton for at least eight years, to be able to vote and stand as candidates for political offices at the cantonal level.

This ‘upgrade’ to the cantonal voting rights is important, supporters argue, because it would enable foreigners to have more political impact.

“Municipal votes are quite rare, and the issues at stake are relatively limited,” the initiative committee said.

Therefore, “access to the cantonal vote will allow these same people to express their views on wider subjects that affect them on a daily basis.”

Is this  measure likely to be accepted?

No reliable forecasts exist at this point.

And while foreigners constitute nearly 40 percent of Geneva’s population — the highest proportion in Switzerland —  it will be up to Swiss citizens to decide on the outcome.

However, some members of the Geneva parliament are urging the ‘no’ vote on June 9th.

“No canton, no country, provides such generous rights to their foreigners,” the MPs from the centre parties pointed out in an interview with Tribune de Genève over the weekend.

(Neuchâtel and Jura allow voting, but not standing for election, at cantonal level).

“The only path for foreigners to obtain full political rights is through naturalisation,” the MPs added.
