They will still piss on you even if you were on fire, Nancy.
The government can't be trusted, with 100% assurance.
When we are freezing our asses off when most of the Northern Hemisphere climate become similar like the last Ice Age.
That if this happen this climate will probably last for centuries.
Because of the shut down of the Ocean Conveyor, because of decrease salinity in sea water cause by global warming effects of melting of glacial ice of the Arctic and Antarctic, that adds fresh water(low salinity) to the world's oceans.

The Great Ocean Conveyor is propelled by the sinking of cold, salty (and therefore denser) waters in the North Atlantic Ocean. That creates a void that pulls warm, salty Gulf Stream waters northward. The Gulf Stream gives up its heat to the atmosphere above the North Atlantic Ocean, and prevailing winds carry the heat eastward to warm Europe.
As that water moves north, it gives up heat and some moisture to the atmosphere, making climates in Europe much warmer and moister than one would expect for a landmass at such high latitude.

The process leaves behind cool, salty water that is denser than surface waters. In the seas that ring the northern Atlantic—the Labrador, Irminger, and Greenland seas—this dense water sinks to the depths and flows southward. These conduits of cold, deep waters converge into the Deep Western Boundary Current, which flows adjacent to and sometimes beneath the Gulf Stream. This sinking and southward flow draws more warm water north to replace it, and contributes to a worldwide circulation pattern known as the Global Thermohaline Circulation, or the "Great Ocean Conveyor."

The freshening tendency makes the surface water more buoyant, thus opposing the cooling tendency. If the freshening is sufficiently large, the surface waters may not be dense enough to sink to great depths in the ocean, thus inhibiting the action of the ocean conveyor and upsetting one important part of the earth’s heating system.

The ocean conveyor need not stop entirely when the NADW(North Atlantic Deep Water) formation is curtailed. It can continue at shallower depths in the N. Atlantic and persist in the Southern Ocean where Antarctic Bottom Water formation continues or is even accelerated. Yet a disruption of the northern limb of the overturning circulation will affect the heat balance of the northern hemisphere and could affect both the oceanic and atmospheric climate. Model calculations indicate the potential for cooling of 3 to 5 degree Celsius in the ocean and atmosphere should a total disruption occur. This is a third to a half the temperature change experienced during major ice ages.

These changes are twice as large as those experienced in the worst winters of the past century in the eastern US, and are likely to persist for decades to centuries after a climate transition occurs. They are of a magnitude comparable to the Little Ice Age, which had profound effects on human settlements in Europe and North America during the 16th through 18th centuries. Their geographic extent is in doubt; it might be limited to regions bounding the N. Atlantic Ocean. High latitude temperature changes in the ocean are much less capable of affecting the global atmosphere than low latitude ones, such as those produced by El Niño.
Then they will regard the physics and chemistry of global warming as facts.
But we will be probably living in snow iglus or ice caves by then, in about one or two decades.
Unless, we are lucky.
