Peter's work to promote awareness of the threat and magnitude of climate change over the years has been truly noble.

Not exact matches

The researchers then went to an intermediate elevation and simulated climate change by reducing the snowpack, which made the plants flower seven days early, similar in magnitude to flowering time shifts over 20 to 30 years of climate change.

To date, Singer and Michaelides have used it to identify real climate change over a broad region, but they are in the process of coupling STORM to a runoff model to explore scenarios of climate change and how they might really affect the magnitude and the frequency of runoff.

The speed and magnitude of climate change may mean that increased forest mortality and contractions in forest distributions will outpace any gains in forest growth and productivity over the long run, leading to a net loss of forested area in Montana.

Climate change will, however, have different impacts on people around the world and those effects will vary not only by region but over time, depending on the rate and magnitude of climate Climate change will, however, have different impacts on people around the world and those effects will vary not only by region but over time, depending on the rate and magnitude of climate climate change.

«But globally over the 21st century, the magnitude and severity of negative impacts are projected to increasingly outweigh positive impacts,» as the Intergovernmental Panel on Climate Change (IPCC) concluded in its comprehensive 2014 literature review on «Impacts, adaptation, and vulnerability.»

The hearing, «Data or Dogma: Promoting Open Inquiry in the Debate over the Magnitude of Human Impact on Earth's Climate,» featured testimony from three scientists who are skeptical of the case for action to address climate change (Prof. Judith Curry of Georgia Tech, Prof. John Christy of the University of Alabama Huntsville and Prof. Will Happer of Princeton University), one mainstream climate scientist (Prof. David Titley of Penn State University), and talk radio personality and author MarkClimate,» featured testimony from three scientists who are skeptical of the case for action to address climate change (Prof. Judith Curry of Georgia Tech, Prof. John Christy of the University of Alabama Huntsville and Prof. Will Happer of Princeton University), one mainstream climate scientist (Prof. David Titley of Penn State University), and talk radio personality and author Markclimate change (Prof. Judith Curry of Georgia Tech, Prof. John Christy of the University of Alabama Huntsville and Prof. Will Happer of Princeton University), one mainstream climate scientist (Prof. David Titley of Penn State University), and talk radio personality and author Markclimate scientist (Prof. David Titley of Penn State University), and talk radio personality and author Mark Steyn.

Over and over again opponents of climate change policies have argued that nations need not act to reduce the threat of climate change because there are scientific uncertainties about the magnitude and timing of human - induced climate change impaOver and over again opponents of climate change policies have argued that nations need not act to reduce the threat of climate change because there are scientific uncertainties about the magnitude and timing of human - induced climate change impaover again opponents of climate change policies have argued that nations need not act to reduce the threat of climate change because there are scientific uncertainties about the magnitude and timing of human - induced climate change impacts.

It suggests that the ocean's natural variability and change is leading to variability and change with enhanced magnitudes over the continents, causing much of the longer - time - scale (decadal) global - scale continental climate variability.

At best, changes of such magnitude would trigger dramatic re-organization of ecosystems across the globe that would play out over the next few centuries; at worst, extinction rates would elevate considerably for the many species adapted to pre-global warming conditions, via mechanisms described above (inability to disperse or evolve fast enough to keep pace with the extremely rapid rate of climate change, and disruption of ecological interactions within communities as species respond individualistically).

The models heavily relied upon by the Intergovernmental Panel on Climate Change (IPCC) had not projected this multidecadal stasis in «global warming»; nor (until trained ex post facto) the fall in TS from 1940 - 1975; nor 50 years» cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005); nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007); nor the onset, duration, or intensity of the Madden - Julian intraseasonal oscillation, the Quasi-Biennial Oscillation in the tropical stratosphere, El Nino / La Nina oscillations, the Atlantic Multidecadal Oscillation, or the Pacific Decadal Oscillation that has recently transited from its warming to its cooling phase (oceanic oscillations which, on their own, may account for all of the observed warmings and coolings over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004 hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.

The magnitude and inter-model range of simulated warming over high northern latitudes are very similar in the high - end and non-high-end models, which indicates that the biases among the models are larger than the climate change signal.
