Sentences with phrase «heat reaches our planet»

Now he estimates that Pinatubo's injection of some 20 million tonnes of sulphur dioxide into the stratosphere has created a temporary thin shroud that has reduced the amount of solar heating reaching the planet's surface by around 4 watts per square metre of the surface.

If cloud cover (especially low clouds) decreases (as it did in the 1980s / 90s), more heat reaches our planet and it eventually begins to warm (as it did).

Not exact matches

«yep, your kid died, but one day our species might evolve into something that survives a while, maybe even reaching other planets before the eventual heat death of our universe.

The general consensus among scientists is that the young Earth's atmosphere contained much larger quantities of greenhouse gases (such as carbon dioxide and / or ammonia) than are present today, which trapped enough heat to compensate for the lesser amount of solar energy reaching the planet.

Equilibrium is not reached for many, many hundreds of years — during which the planet heats up, and continues to heat up for a long while after the extra carbon stops being added.

But also too more density would be less heat actually reaching the planets surface.

Here we start with endlessly faulty data — from instruments parked on urban «heat islands» to severely massaged data bases of daily temperature readings, from sketchy numbers for the vast reaches of the planet where there are almost no readings, to expurgation of decades of inconvenient data.

In this case the shell heats the planet, but not forever, just until a new equilibrium is reached.

What's more, only a few years ago AGW proponents, such as Bill McKibben, launched a noisy campaign warning that if CO2 levels reached 350 parts per million (ppm) we would have heated the planet past the point of no return.

However, planets will eventually reach new equilibrium states where the heat - loss balances the energy input.

All that happens when you start off with a very cold or a very hot «radiating temperature» relative to the incoming radiation is that the planet heats up or cools down until it reaches its equilibrium.

The planet has warmed by 0.8 ºC above the pre-industrial average already and inertia in the system means that 2.4 ºC of warming is already locked in, with heating reaching 4ºC perhaps in the 2070s.
