Sentences with phrase «scale climate drivers»

The team of researchers say their findings also suggest that the fluctuations of large - scale climate drivers have changed, leading to more frequent events associated with El Niño or La Niña.

Not exact matches

«We weren't anticipating that there were going to be these two distinct regions,» said Reiner, who was surprised to see that a global climate driver had such fine - scale consequences.

Scientists have long predicted large - scale responses of infectious diseases to climate change, giving rise to a polarizing debate, especially concerning human pathogens for which socioeconomic drivers and control measures can limit the detection of climate - mediated changes.

An unprecedented analysis of North Pacific ocean circulation over the past 1.2 million years has found that sea ice formation in coastal regions is a key driver of deep ocean circulation, influencing climate on regional and global scales.

Lyons and coauthors, along with research groups from around world over, are focusing current efforts on the timing and drivers of oxygenation in the late Proterozoic, favoring a combination of global - scale mountain building, evolutionary controls on the way carbon is cycled in the biosphere, and concomitant climate events.

The results indicate that although land - use change is currently considered as the major driver of pollinator declines in Europe, climate is the most important factor limiting the distribution of pollinators at large spatial scales.

The study incorporates multiple environmental drivers — notably climate and fire — at large spatial scales for a significant number of species and populations.

Findings of thousands of scientists have determined that the biggest driver of warming of the planet and the resulting climate change is industrial - scale coal burning.

Primary driver for long scale climate change is orbital configuration.

It merely highlights the fallacy of looking for one single «driver» that explains climate variations on all time scales.

Certainly, there is no reason to believe that CO2 as a climate driver has been undermined in any way, especially on shorter time scales.

A major focus of this work is to explore the propagation of uncertainty from external drivers to actual impacts of climate change on time - scales of up to 30 years.

In a paper in Geoscience Canada, Veizer (2005) states that «the multitude of empirical observations favours celestial phenomena as the most important driver of terrestrial climate on most time scales `.

Global - scale variations are therefore much smaller, and they reflect changes in global climate drivers, for example in greenhouse gas concentrations or in solar activity.

Since a primary driver of the Earth's climate from year to year is the El Nino Southern Oscillation (ENSO) acts on time scales on the order of 2 - 7 years, and the fact that the bulk of the Southern Hemisphere hurricane season occurs from October — March, a reasonable interpretation of global hurricane activity requires a better metric than simply calendar year totals.

Most authors identify government practices as being far more influential drivers than climate variability, noting also that similar changes in climate did not stimulate conflicts of the same magnitude in neighboring regions, and that in the past people in Darfur were able to cope with climate variability in ways that avoided large scale violence.

However, to understand the large scale patterns in climate and their changes and drivers, climate models are not only useful, but increasingly necessary to make skillful predictions for the future.

Furthermore, CO2 isn't the only greenhouse gas and climate change isn't strictly relegated to GHG emissions nor are CO2 concentrations in the atmosphere the only climate driver (i.e., there are many drivers of climate which take place on the millions of years time - scale).

Precipitation extremes and small - scale variability are essential drivers in many climate change impact studies.

Drivers of the land climate system have larger effects at regional and local scales than on global climate, which is controlled primarily by processes of global radiation balance.

In Cancún, the imperative of including agriculture and biofuels; or to decide on a blueprint for mitigation of emissions caused by bunker fuels; or to define system - wide, large - scale levers for market - based action on mitigation and adaptation; or, establish new approaches that differentiate and foster innovation for climate from technological drivers in other areas and in the past, were all avoided.

In March 2005, Jan Veizer, one of Canada's top Earth scientists, published a comprehensive review of recent findings and concluded that «empirical observations on all time scales point to celestial phenomena as the principal driver of climate, with greenhouse gases acting only as potential amplifiers.»

It is only over the longer time scales (decades) that the additional predictability that comes from external drivers of climate change (for instance, carbon dioxide, air pollution and ozone depletion) can start to be useful — but that's another post.

These cycles are clearly the primary drivers of climate change on the scale of roughly 100,000 years, 40,000 years and 20,000 years.

Unlike you, I do not have a «Magic 8 Ball», but I see that a considerable amount of money is being spent to do a large - scale test at CERN of the GCR cloud nucleation hypothesis suggested by Henrik Svensmark (and others) to have been a significant driver of our climate, which Svensmark et al. tested in at a small scale in the laboratory.

Because the drivers of climate change are truly global, even dedicated action at the regional scale has limited prospects for ameliorating regional - scale impacts.

At all human - relevant time - scales, the Sun is the dominant driver of our ever - changing climate.

It is not possible to calculate the effect of anthropogenic CO2 until we know within closer limits what the natural variation is.For example if you look at the ice core data for the Holocene and if you believe that CO2 is the climate driver you would have to conclude that on a scale of thousands of years CO2 was an Ice House — not a green house gas.For the data and an estimate of the coming cooling for the next few hundred years check the post» Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.climate driver you would have to conclude that on a scale of thousands of years CO2 was an Ice House — not a green house gas.For the data and an estimate of the coming cooling for the next few hundred years check the post» Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.»

So while it may be theoretically possible to predict long - scale climate changes, it may still be impossible to discern the true drivers of these climate systems amidst the chaos, making the long - term prediction problem moot.
