Not exact matches

«But if the current trajectory of carbon pollution levels continues unchecked, the world is on track for at least three degrees of warming.

And while Evans is dependably warm and supportive (as well as a refreshing representation of a man professing the need for men and boys to learn how to respect women and the art of submission), Robinson's film draws considerable strength from Hall and Heathcoate, who dance a sometimes - impossible duet of presenting characters with authentic romantic trajectories and maintaining a fount of chemistry to boot.

On the overarching question of «solving» the climate problem, I'm sure Joe would agree that global warming is inevitably going to be, at best, managed — not «fixed» — given the trajectories for emissions in a world inexorably headed toward roughly nine billion people seeking energy - enabled lives and with substantial warming already in the pipeline, according to a heap of research.

This is the difference between countries» pledged commitments to reduce emissions of heat - trapping greenhouse gases after 2020 and scientifically calculated trajectories giving good odds of keeping global warming below the threshold for danger countries pledged to try to avoid in climate talks in 2010 (to «hold the increase in global average temperature below 2 °C above pre-industrial levels»).

The world should take note that the climate summit in Paris later this year (COP21) may be the last effective opportunity to negotiate arrangements that keep human - induced warming below 2 - degrees C, and aim to stay well below 2 - degree C for safety, yet the current trajectory may well reach a devastating 4 - degrees C or higher;

And when you look at the trajectories for emissions, and for what you would need to do to blunt warming, you realize that if we keep sort of dilly - dallying we will be in trouble.

Taken another way, from a climate perspective, the total area under the emissions trajectory matters more for peak warming than the shape of that curve.

Much more frightening than any of this is the fact that plenty of mainstream analysts think that on our current emissions trajectory, we are headed for even more than 4 degrees of warming.

Even in the simple Lorentz case I think that making the attractor a bit «warmer,» presumably by moving one of its edges in the «warmer» direction, has no implications for the behavior of any finite segment of any trajectory within the attractor.

For we have already burned enough fossil fuel to keep warming on the trajectory to hit 1.5 to 2.5 C this century and 3 - 5 C or somewhat more long term — a bad result, and one that would likely require extensive human deployment of atmospheric carbon capture technologies.

In figure 1, we calculated the warming trajectories not only for emission pathways with zero emissions floors, but also for pathways with non-zero floors.

A sample emission pathway for each of the plots above is given in figure 1, alongside its resultant warming trajectory.

But if we ask ourselves what kind of diplomatic agreement would set the world on a trajectory leading to much stronger commitments, so that warming might be contained within the 2 °C guardrail or better, then what happened in Paris is as good as could be hoped for.

Second, ignore the inconsistencies, and just assume those pesky CO2 molecules are so clever that they can change the trajectory of planetary temperature trends every few decades, from warming to cooling, back to warming, then just «flatline» for fifteen years or so.

The science - based targets approach is in line with the latest Intergovernmental Panel on Climate Change report which calls for a global emission trajectory to keep global warming below 2 degrees Celsius.

Meanwhile, more than half of all industrial carbon emissions have occurred since 1988 - and the world remains on a trajectory for substantial and dangerous global warming.

4) the end results on the bottom of the first table (on maximum temperatures), clearly showed a drop in the speed of warming that started around 38 years ago, and continued to drop every other period I looked / /... 5) I did a linear fit, on those 4 results for the drop in the speed of global maximum temps, versus time, ended up with y = 0.0018 x -0.0314, with r2 = 0.96 At that stage I was sure to know that I had hooked a fish: I was at least 95 % sure (max) temperatures were falling 6) On same maxima data, a polynomial fit, of 2nd order, i.e. parabolic, gave me y = -0.000049 × 2 + 0.004267 x — 0.056745 r2 = 0.995 That is very high, showing a natural relationship, like the trajectory of somebody throwing a ball... 7) projection on the above parabolic fit backward, (10 years?)

GHG emission trajectories that are consistent with the goal of keeping global warming below 1.5 or 2ºC, translate into a global carbon budget that represents a de-facto emissions cap for the whole economy.

In the natural gas scenario, the study calculated a range of warming trajectories for warming 100 years from now, with temperatures 17 to 25 percent lower than they would be if the world stuck with coal.

But the cut in the warming trajectory was far sharper for a switch to energy sources with near - zero emissions — such as nuclear, wind, or solar energy.

In addition, the rate of warming for a given CO2 trajectory is sensitive to both positive (CO2) and negative (aerosol) forcings, and so higher sensitivity to both will change in the trend in an uncertain direction depending on the balance of these forcings.

Overvaluing the influence of CH4 emissions on climate could easily result in our «locking» the earth into a warmer temperature trajectory, one that is temporarily masked by the short - term cooling effects of the CH4 reductions, but then persists for many generations.

The agreement allows the EU to continue pursuing a roadmap that is intended to arrive at a reduction of carbon output of 80 - 95 % by 2050, in line with IPCC recommendations for keeping within a 2C trajectory of global warming.

The exact warming resulting from this delay depends on the trajectory of future CO2 emissions but using one business - as usual - projection we estimate an increase of 3/4 °C for every 15 - year delay in CO2 mitigation.

On a continued «business as usual» trajectory, the world will burn through about 5 times that safety limit by 2100, putting the world on a path for warming of more than 4.5 degrees Celsius and about a meter of additional sea level rise.
