Thus, the conceptualization that human activity or CO2 concentration changes are the primary drivers of temperature changes and sea level rise does not seem to be supported by the geological evidence.

Not exact matches

Sea - surface temperature is an important driver of the weather, and because the oceans change temperature very slowly compared with the air and land, they form a key, predictable component of seasonal forecasts.

«This underscores that large, sustained changes in global temperature like those observed over the last century require drivers such as increased greenhouse gas concentrations,» said lead author Patrick Brown, a PhD student at Duke's Nicholas School of the Environment.

Kevin Trenbeth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., said the study didn't account for changes in sea surface temperatures, which are the main drivers of changes in the position of the rain belts (as is seen during an El Nino event, when Pacific warming pushes the subtropical jet over the Western U.S. southward).

The researchers also compared phytoplankton's response not only to ocean acidification, but also to other projected drivers of climate change, such as warming temperatures and lower nutrient supplies.

With 755 horsepower the 2019 Chevrolet Corvette zr1 is the most powerful Corvette ever it's also the most technologically advanced behind me are the rolling s's at Road Atlanta and we're here to see if we can reach to the supercar levels of performance afforded by this thing's massive power big tires and the tall wing on the back after that we'll take to the streets to see if a car this powerful can behave itself in public this is a monster of a car I've had some brief track opportunities moving this morning to get used to the pace of this machine which is phenomenal we're gonna warm up as we get out to the road Atlanta and sort of build up to the pace that this car can operate at now initially when you hop in this car you have this shrine to the engine right above you you see the line of the hood it kind of dominates the center of the view you can see over it it doesn't affect visibility but it's immediately obvious and that kind of speaks to what makes this car special it's a monster of an engine listen to that [Music] that is tremendous tremendous acceleration and incredible power but what I finding so far my brief time here at the Atlanta is that everything else in the car is rut has risen to match hurt me while I lay into it on the back straight look you know 150 mile - an - hour indicated we're going to ease up a little bit on it because I need to focus on talking rather than driving but like I was saying the attributes of the rest of the car the steering the braking capability the grip every system of this car is riding to the same level of the power and I think that's what makes it really impressive initially this is undoubtedly a mega mega fast car but it's one that doesn't terrify you with its performance potential there's a level of electronic sophistication that is unparalleled at this price point but it's hard not to get you know totally slipped away by the power of this engine so that's why I keep coming back to it this car has an electronically controlled limited slip differential it has shocks filled with magnetically responsive fluid that can react faster to inputs and everything this car has a super sophisticated stability control system that teaches you how to drive it quick but also makes you go faster we haven't even gotten into exploring it yet because the limits of this car are so high that frankly it takes a while to grow into it but [Music] I think what's impressive about this car is despite how fast it is it is approachable you can buy this car to track dates with it and grow with it as a driver and as an owner I think that's a really special [Music] because you will never be more talented than this car is fast ever unless you are a racing driver casually grazing under 50 miles an hour on this straight okay I'm just going to enjoy driving this now [Music][Applause][Music] this particular Corvette zr1 comes with the cars track performance package a lot of those changes happen underneath the sheet metal but one of the big differences that is immediately obvious is this giant carbon fiber wing now the way this thing is mounted is actually into the structure of the vehicle and it makes you know loading the rear hatch a bit more difficult but we're assuming that's okay if you're looking for the track performance this thing delivers also giving you that performance are these Michelin Pilot Sport cup tires which are basically track oriented tires that you can drive on the street but as we wake our way to the front of the thing what really matters is what's under the hood that's right there's actually a hole in the hood of this thing and that's because this engine is so tall it's tall because it has a larger supercharger and a bunch of added cooling on it to help it you know keep at the right temperature the supercharger is way larger than the one on the zo six and it has a more cooling capacity and the downside is it's taller so it pops literally through the hood the cool thing is from the top you can actually see this shake when you're looking at it from you know a camera from the top of the vehicle this all makes for 755 horsepower making this the most powerful Corvette ever now what's important about that is this not just the power but likewise everything in the car has to be built to accommodate and be able to drive to the level of speed this thing can develop that's why you had the massive cooling so I had the aerodynamics and that's why I had the electronic sophistication inside [Applause] we had a lot of time to take this car on the track yesterday and I've had the night to think about things Matt today two crews on the road and see how this extreme performance machine deals with the sort of more civil minded stuff of street driving the track impressions remain this thing is unquestionably one of the most capable cars you can get from a dealer these days a lot of that's besides the point now because we're on the street we have speed limits they have the ever - present threat of law enforcement around every corner so the question is what does this car feel like in public when you slow this car down it feels like a more powerful Corvette you don't get much tram lining from these big wheels though we as the front end doesn't want to follow grooves in the pavement it is louder it is a little firmer but it's certainly livable on a day to day basis that's surprising for a vehicle of this capability normally these track oriented cars are so hardcore that you wouldn't want to drive them to the racetrack but let's face it you spend more time driving to the track than you do on the track and the fact that this thing works well in both disciplines is really impressive I can also dial everything back and cruise and not feel like I'm getting punished for driving a hardcore track machine that's a that's a really nice accomplishment that's something that you won't find in cars that are this fast and costs maybe double this much the engine in this car dominates the entire experience you can't miss the engine and the whole friend this car is sort of a shrine to it the way it pops out of the hood the way it's covered with coolers around the sides it is the experience of this car and that does make driving this thing special and also the fact that it doesn't look half bad either in fact I think it has some of the coolest looking wheels currently available on a new car this car as we mentioned this car has the track package the track package on this car gives you what they call competition bucket seats which are a little wide for my tastes but I'm you know not the widest person in the world this automatic transmission works well I mean there's so much torque again out of this engine that it can be very smooth and almost imperceptible its clunky on occasion I think I'd might opt for the manual although Chevy tells me about 80 % of its customers will go for the automatic I don't think they're gonna be disappointed and that's gonna be the faster transmission drag strip on the street - and on the racetrack man it was a little bit more satisfying to my taste though we've talked about the exhaust I have it set in the track setting let's quiet it down a little bit so you can hear the difference now I've set that separately from everything else so let's put it stealth what happened to the engine sound that's pretty that's pretty amazing man stealth is really stealth and then go back to track Wow actually a really big difference that's that's pretty great the Corvette has always been a strong value proposition and nowhere is that more evident than this zr1 giving you a nearly unbeatable track performance per dollar now the nice thing is on the road this doesn't feel like a ragged edge track machine either you could genuinely drive it every day the compromises are few and that's what makes this car so special if you like what you see keep it tuned right here and be sure to visit Edmunds.com [Music]

The assessment considered the impacts of several key drivers of climate change: sea level change; alterations in precipitation patterns and subsequent delivery of freshwater, nutrients, and sediment; increased ocean temperature; alterations in circulation patterns; changes in frequency and intensity of coastal storms; and increased levels of atmospheric CO2.

Although the primary driver of glacial — interglacial cycles lies in the seasonal and latitudinal distribution of incoming solar energy driven by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial temperature and ice volume changes can not be explained without accounting for changes in atmospheric CO2 content and the associated climate feedbacks.

All of the models ca 2007 that the IPCC used to forecast climate change predicted a steady increase in temperature (based, as they were, on the assumption that CO2 is the primary driver of temperature) and yet global temperatures have remained essentially flat since then.

Re «Estimates of the drivers of global temperature change in the ice ages show that the changes in greenhouse gases (CO2, methane and nitrous oxide) made up about a third of the effect, amplifying the ice sheet changes by about 50 % (Köhler et al, 2010).»

Instead, the web special opened with «Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change», which sounds a bit ho - hum, if not, well, duh?

While Spencer hypothesizes that the changes in cloud cover are the main driver behind global warming, Dessler concludes that they're only responsible for a small percentage of the changes in surface temperature from 2000 to 2010.

That property of water could be enough to enable the weather processes overall to stabilise the whole process and is one of the reasons why oceanic temperature is, always has been and always will be the primary atmospheric temperature driver and will always reduce or possibly neutralise any effect of an enhanced greenhouse effect in the absence of really huge changes caused by astronomic or geological processes.

One driver of temperatures in this region is the abundance and variability of ozone, but water vapor, volcanic aerosols, and dynamical changes such as the Quasi - Biennial Oscillation (QBO) are also significant; anthropogenic increases in other greenhouse gases such as carbon dioxide play a lesser but significant role in the lower stratosphere.

«Many other important impacts of climate change are difficult to quantify for a given change in global average temperature, in part because temperature is not the only driver of change for some impacts; multiple environmental and other human factors come into play.»

Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change.

Carbon dioxide can cause temperatures to rise without being the primary driver, or even a significant driver, of climate change.

If cloud cover can vary as noted per the paper, and just a few percent change in cloud cover can have a large effect to temperatures, then how much confidence can one have in the «CO2 is the greatest driver of increased temperatures?

However, while Spencer hypothesizes that the changes in cloud cover are the main driver behind global warming, Dessler concludes that they're only responsible for a small percentage of the changes in surface temperature from 2000 to 2010.

When models only include natural drivers of climate change, such as natural variability and volcanic eruptions, they can not reproduce the recent increase in temperature.

Hence, changes in temperature due to climate change are expected to be one of the important drivers of change in natural and managed systems.

The evidence suggests a strong statistical relationship for the SO being the primary driver of temperatures and potential climate change.

In particular, given that there has been no trend in the sunspot count or cosmic ray flux over the last 50 years [1], while the global temperature has increased by 0.5 - 0.6 °C [2], how can one seriously claim that your work shows solar activity to be the major driver of climate change today and over the last 50 years?

Ozone depletion in the late twentieth century was the primary driver of the observed poleward shift of the jet during summer, which has been linked to changes in tropospheric and surface temperatures, clouds and cloud radiative effects, and precipitation at both middle and low latitudes.

At present, atmospheric temperature is decreasing and CO2 is increasing again showing that CO2 is not the principal driver of climate change.

He states «Global Warming is over and there is no evidence that CO2 ever was, is or will be a driver of world temperatures or Climate Change - indeed evidence is the relationship is more the other way around».

To identify major drivers of southwestern climate change we perform a multiple - linear regression of the past 100 years of the southwestern US temperature and precipitation.

Projected changes in physical and biogeochemical drivers such as temperature, CO2 content and acidification, oxygen levels, the availability of nutrients, and the amount of ocean covered by ice, will affect marine life.

Greenhouse gases, including CO2, looking less and less the major drivers of global temperatures and climate change.

One of the problems with irradiance as a driver for climate change is that though the changes seem to be fairly well correlated with the temperature anomaly, many scientists think the magnitude is too small to totally account for temperature changes.

As the energy transfer is a combination of Joule heating and particle precipitations then the main drivers of the ionospheric response to recurrent geomagnetic activity are related to changes in the temperature, thermospheric neutral composition, and neutral winds.

«Whilst there are certainly other potential drivers of changes in the climate we know that over the last century we have greatly increased the CO2 concentration in the atmosphere and, through detection and attribution analyses, we know that the rising levels of atmospheric CO2 and other greenhouse gases have driven the rise in global temperature,» King said.

This would be true if the only thing changing was the precipitation rate, but this is obviously not the case because the driver of all these precipitation changes is the expected significant increase in air temperature.

CO2 is not the only driver of climate and temperature changes, it's a small influence at best.

However, if the models of Don Easterbrook etc. show global temperature varying with the Pacific Decadal Oscillation (PDO)(not just regional temperature), then the models themselves are missing major physics and the drivers of both PDO and temperature changes.

The study estimates climate sensitivity — how much the world will warm when carbon dioxide levels increase * — from changes in observed temperatures and estimates of the warming effect of greenhouse gases and other drivers of climate change, from the mid / late 19th century until 2016.
