Sentences with phrase «slow climate change then»

Not exact matches

If the researchers incorrectly estimated a 200,000 - year - old salamander species to be 2 million years old, then their result was off by a factor of 10, making the salamander's rate of evolution 20,000 times slower than climate change instead of 200,000 times slower.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

Most climate change predictions, when they incorporate population growth at all, have been based on the long - standing assumption that the planet's burden of humans will peak around 2050, and then begin a slow decline.

Human - induced forcing exhibited a slow rise during the early part of the last century but then accelerated after 1960.2 Thus, these graphs highlight observed changes in climate during the period of rapid increase in human - caused forcing and also reveal how well climate models simulate these observed changes.

If MJ's death motivated to you spend 4 minutes listening to song you wouldn't have listened to last week, then email your Senators and tell them the climate change bill before them is far too weak and too slow.

A new assessment by the Intergovernmental Panel on Climate Change (IPCC) concludes that the world community could slow and then reduce global emissions of greenhouse gases (GHGs) over the next several decades by exploiting cost - effective policies and current and emerging technologies.

But concrete action to address climate threats has been relatively slow, critics say, and a convoluted process of devolution of power to Pakistan's provinces and then the reorganisation of federal ministries hasn't helped speed up the process — though a new federal Ministry of Climate Change may help changclimate threats has been relatively slow, critics say, and a convoluted process of devolution of power to Pakistan's provinces and then the reorganisation of federal ministries hasn't helped speed up the process — though a new federal Ministry of Climate Change may help changClimate Change may help changeChange may help changechange that.

Slowing the growth rate of GHG emissions and then reversing it is the key to addressing climate change and keeping global average temperature below 2 °C above pre-industrial levels.

Glacial — interglacial oscillations of the CO2 amount and ice sheet size are both slow climate feedbacks, because glacial — interglacial climate oscillations largely are instigated by insolation changes as the Earth's orbit and tilt of its spin axis change, with the climate change then amplified by a nearly coincident change of the CO2 amount and the surface albedo.
