Sentences with phrase «cause runaway climate»

Climate scientists like James E. Hansen predict that methane clathrates in the permafrost regions will be released because of global warming, unleashing powerful feedback forces which may cause runaway climate change that can not be halted.

Her chain of reasoning is that i) flights cause CO2, ii) CO2 causes global warming, iii) which will cause runaway climate change, iv) which kills people — the WHO says so, v) these are mostly poor people in other countries.

Not exact matches

Thus, only human - made emissions, such as factory and car secretions, could cause runaway global climate change because they lack natural negative feedbacks to balance them.

The most extreme risk envisioned in all climate studies is surely a runaway greenhouse effect, in which human activities cause a buildup of CO2 to a level (ca. 1400 ppm).

Past mass extinctions caused by runaway GW (then, obviously, triggered by a convergence of natural events), resulting in few left to breath out CO2 (among other constraints), leading to stabilization and retreat back to a climate more hospitable to a wide range of biota.

(There are equilibrium climates between the points where the runaway starts and where it ends, but they are unstable equilibria, and the equilibrium coverage of snow / ice increases with forcing that would cause warming.)

When all the water available has gone into the atmosphere, the runaway process stops, and it requires additional external forcing to cause additional climate change.

The sudden release of large amounts of natural gas from methane clathrate deposits in runaway climate change could be a cause of past, future, and present climate changes.

Jamail adds, «There is nothing to indicate in the political or corporate world that there will be anything like a major shift in policy aimed at dramatically mitigating runaway anthropogenic [human - caused] climate disruption.»

I am convinced next Monday there will be a newspaper explaining the cold and the snow was caused by» extremely dangerous human induced runaway global warming as the driver of climate change».

Any normal person would conclude that CO2 is not causing runaway global warming, climate catastrophe, or for that matter, any other problems.

One of the biggest debates between sceptics and their counterparts is in fact the role played by feedback mechanisms — a response in part to claims by environmentalists such as Mark Lynas in «Six Degrees: our future on a hotter planet» that a relatively small increase in CO2 could cause «runaway climate change» by triggering (unknown and possibly non-existent) feedback mechanisms to form.

As it stands there's no empirical evidence of any sort that CO2 causes climate warming, and indeed now the ipcc is maintaining that CO2 is both a cause and an effect of temperature change, which, unless CO2 was only an insignificant contributor to warming, would without a doubt lead to a runaway greenhouse with boiling oceans.

What they are practicing is not science, it is propaganda based on an unsupportable catastrophic AGW agenda designed to convince the public that a rise in a tiny trace gas comprising only 0.00038 of the atmosphere will cause runaway global warming and climate catastrophe.

Runaway climate change caused by methane deposits.

The cumulative CO2 growth causes global warming that accelerates (they hypothesize) to a condition of «runaway» temperature increases via positive feedbacks, leading to catastrophic «tipping point» climate change.

If CO2 AGW theory is correct, the climate would be so unstable that H2O itself would have caused a runaway «greenhouse effect», without needing CO2:

Why, after billions of years, it is ASSUMED that suddenly small changes will cause rampant runaway climate behavior is beyond me.

Ingersoll [105] discussed the role of water vapours in the «runaway greenhouse effect» that caused the surface of Venus to eventually become so hot that carbon was «baked» from the planet's crust, creating a hothouse climate with almost 100 bars of CO2 in the air and a surface temperature of about 450 °C, a stable state from which there is no escape.

Regarding that last point, consensus climate science has proposed a hypothesis on the claim that climate physics dictates that rising atmospheric CO2 levels will warm the atmosphere substantially, thus causing a positive feedback loop, which will then continuously accelerate warming until a tipping point of runaway temperatures take place, turning Earth into the next Venus.

We need those using the «game over» rhetoric to lay out the climate crisis's root causes — because just as one project is not the end of humanity, stopping one project will not stop runaway climate change.

On the right, runaway climate change causes warming of more than 10 °C in some regions, extreme rainfall and droughts become the norm, the Arctic becomes ice - free in the summer, and the ocean becomes much more acidic:

How many civilization are out there which caused a warm climate shift or runaway state?

But of course that has nothing to do with the only issue that matters: will an increase in CO2 cause runaway global warming and climate catastrophe?
