Re: Climate, melting ice and sea level
Uh, it's much worse than I thought ... but on what horizon? 2050? 2100?
Still, if each person concerned simply donated € 1 per year to combat global warming, that would already make a few billion dollars invested by then ... but what is the climate police doing ???

As a reminder, the fight against global warming means limiting it to + 2 ° C for the end of the century.

Ah yes just ... I think that we will not succeed ... so we can estimate that it is on the horizon 2050-2100 ... in short, it is "tomorrow" on the geological scale .. .

It's concrete and it's clear: no more or less hypothetical curves ...
It may be snowy again in June 2018 ... or not ...

The problem is that the poles of March also melt, on Jupiter there are 3 times more storms than before, and even on Pluto (6 months light from here) the atmosphere has changed. It is powerful our CO2!

Armand M, we are on earth
Christophe, this year is exceptional: By my home, the wheat is already ripe, whereas it is usually the first week in August.
The worst is for the inhabitants of the Sahel http://www.rfi.fr/afrique/20170330-sech ... -mois-juin

I don't see the connection ... and your statements seem to me to be quite false:
- The March poles are melting? Source? It is -65 ° on average in March and even with an atmospheric pressure of only 1000 Pa (1% of that of the Earth) ... I do not see how it could melt ...
- 3 times more storm on Jupiter than before? What before what?
The famous mega storm (the eye of Jupiter where the Earth could rush) is, on the contrary, slowing down it seems to me ... after more than 300 years of activity
- Is there an atmosphere on Pluto? It's new?

Re: Climate, melting ice and sea level
Florida rising waters will cost homeowners billions in 30 years
By Sciences et Avenir with AFP 19.06.2018
An American organization warns of the future cost of floods linked to the rising waters, according to it underestimated. Too many properties are at risk of chronic flooding even though the floodplain maps have not been updated for a long time.
Storm in Florida on the Key West Islands
On the Florida coast, the real estate market is in great shape despite repeated flooding. Tens of thousands of homes are at risk, although they are not officially classified as flood zones, warns a new report released on June 18, 2018 by the Union of Concerned Scientists (UCS), an American scientific organization. In Florida alone, 64.000 homes, worth a total of $ 26 billion, are at risk of chronic flooding in the next 30 years, the usual length of mortgage loans in the United States.
"A short-term risk, long before the waters rise"
Just a few blocks from the beaches, just outside the flood zones, developers are still busy building houses that have no legal obligation to purchase flood insurance, a short-term economy that heralds economic disaster long term, according to UCS. Across the United States, 311.000 coastal homes, worth $ 120 billion, are at risk of chronic flooding by 2045, the report said.
This risk of flooding has nothing to do with hurricanes and storms: the danger comes from high tides, increasingly high, when water spills in the streets, on the sidewalks, in the shops and the houses - even in good weather. "This risk exists in the relatively short term, long before everything is completely inundated, and it can happen without a storm," explains Rachel Cleetus, economist at UCS. However, the real estate market does not take these risks into account, says the researcher, who warns that an economic correction is inevitable.
Slow motion disaster
The organization has published on its website an interactive map showing the areas most at risk according to it, based on a scenario of high sea levels. For homeowners, whose home is often the most important asset, it is necessary to take into account the upper end of the risk range, says Rachel Cleetus. Chronic flooding is defined as occurring at least 26 times a year.
In Florida, ocean levels are expected to rise 55 centimeters by 2045, and 1,95 m by 2100, under this scenario - while the average elevation in the state is around 1,80 m, and that a lot of places are below zero. "It's a slow-motion disaster", summarizes the economist. Miami, the Tampa Bay and the very touristic Keys Islands are the most exposed in Florida. Entire neighborhoods could be permanently flooded, at an astronomical cost for owners but also for municipalities, which would lose population and tax revenue.
