Sentences with phrase «hothouse climates»

We are converting the climate of our planet to one that is similar to the hothouse climates that existed on this planet when dinosaurs were the top predators.

Reconstructions of past Hothouse climates had shown that temperatures had been around six degrees higher on average, and higher still in polar regions, with no polar ice - caps and a temperate to subtropical fauna and flora, as evidenced by the fossil record in these areas.

Such states may have prevailed in the distant past, but there is nothing about the current Holocene climate to suggest that more than a single equilibrium is within range — we are not close to a new glaciation nor a new «hothouse climate» (although the latter might become possible if continued greenhouse gas emissions were to remain unmitigated for a prolonged interval).

He slammed those who support a «fundamentally immoral» policy of delivering a hothouse climate to future generations, especially since avoiding the worst outcomes requires means redirecting at most 2 % of our wealth.

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.

Not exact matches

Human effects on the climate notwithstanding, the cycle will continue to turn, the hothouse period will some day come to an end — and the ice sheets will descend again.

Unlike the case of the D - O events and Younger Dryas which tell us something about what abrupt change is like in cold climates, we have no analogous climates we can look at to see what abrupt changes might be like in a hothouse world.

There is nothing there that implies that the massive climate fluctuations of the past (e.g. Cretaceous hothouse to Pleistocene icehouse) are independent of CO2.

Unlike the case of the D - O events and Younger Dryas which tell us something about what abrupt change is like in cold climates, we have no analogous climates we can look at to see what abrupt changes might be like in a hothouse world.

Its main goal is to stabilize hothouse emissions in the air at the level that would pose no danger of anthropogenic impact on the climate.

Bart Verheggen says: August 14, 2011 at 3:03 am So how do past climate changes (from snowball earth to the hothouse Cretaceous) fit in your paradigm that «that the temperature of the Earth is kept within a fairly narrow range through the action of a variety of natural homeostatic mechanisms.»?

The document focused on hothouse emissions that have the greatest impact on the climate.

Dr. Soon: Earth's climate system dynamically oscillates between icehouse and hothouse conditions in geological time or, to a lesser degree, between the glacial and interglacial climates of the last 1 — 2 million years.

Last time the earth had 500 - 700 ppm it was an iceless hothouse with very high sea levels, and current climate science can explain why.

Globally in the hothouse that is climate blogging — does anyone believe you Doug?

The Triassic was also a hothouse world: a time of high atmospheric carbon dioxide, rapid climate shifts, and fast - moving extinctions.

The runaway greenhouse effect has several meanings ranging from, at the low end, global warming sufficient to induce out - of - control amplifying feedbacks, such as ice sheet disintegration and melting of methane hydrates, to, at the high end, a Venus - like hothouse with crustal carbon baked into the atmosphere and a surface temperature of several hundred degrees, a climate state from which there is no escape.

Is it true that the amplitude of the climate swings is much less in HotHouse times than in ColdHouse times (such as we are in now)?

There are climate doomsday proponents and alleged «experts» who fear that Earth is warming so fast that it will soon reach hothouse Venus - like temperatures, primarily due to humans continuing global emissions of CO2, a trace greenhouse gas.

Although climate throughout Earth's history has varied from «snowball» conditions with global ice cover to «hothouse» conditions when glaciers all but disappeared, the climate over the past 10,000 years has been remarkably stable and favorable to human civilization.

It started in the 17th century when there was no industrial influence on the climate to speak of and no such thing as the hothouse effect.
