Four reasons why the fight against climate change is likely to fail

March 15, 2014

Democrats in the Senate stayed up all night talking about the perils of climate change. But while there's hope that technology, changing consumer and business practices or new policies could finally turn the tide and slow or reverse climate change, there are also good reasons to think those efforts will fail. [...]

Atmosphere and Ocean Dynamics through the Lens of Model Systems

Atmosphere, Climate Modeling, Ocean
Posted on November 29, 2013 by Guest Blogger | Reply

The atmosphere and ocean are central components of the climate system, where each of these components is affected by numerous significant factors through highly nonlinear relationships. It would be impossible to combine all of the important interactions into a single model. Therefore, determining the contribution of each factor, in both a quantitative and qualitative sense, is necessary for the development of a predictive model, not to mention a better understanding, of the climate system.

Ocean Acidification and Phytoplankton

Biosphere, Inverse Problems, Ocean
Posted on September 4, 2013 by Guest Blogger | Reply

The health of the world’s oceans has been in the news a lot over the last few months. Recent reports suggest that the oceans are absorbing carbon dioxide at unprecedented rates. The ocean is the dominant player in the global carbon cycle, and the sequestering of more carbon dioxide, a major greenhouse gas, sounds like a good thing. However, researchers have measured significant increases in ocean acidity, and they worry this will have a negative impact on marine life, especially phytoplankton. Continue reading →

How Vegetation Competes for Rainfall in Dry Regions

Biosphere, Mathematics, Patterns
Posted on September 2, 2013 by Hans Kaper | Reply

The greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is a limited resource in many dry ecosystems, such as semi-arid environments and semi-deserts, there is a benefit to vegetation to adapt by forming closer networks with little space between plants.

Observing collective phenomena such as the movement of a flock of birds, a school of fish, or a migrating population of ungulates is a source of fascination because of the mystery behind the spontaneous formation of the aggregating behavior and the apparent cohesiveness of the movements. However, they can also be the cause of a major environmental and social problem when one thinks, for example, of the flight of a swarm of voracious locusts ravaging crops in various parts of the world and putting many communities under severe stress.

There are two standard ways to restrict harvesting of fish in order to maintain or improve the population. One way is to establish marine protected areas where fishing is prohibited and the other is to allow fishing everywhere but at something less than maximal capacity. Just a few days ago I noticed an interesting preprint in ArXiV that sets up a mathematical framework for deciding whether protected areas should be used and, if so, where they should be established.

Some universality in fractal sea coasts?

Geophysics, Ocean
Posted on April 27, 2013 by Christiane Rousseau | Reply

Sandy coasts have a smooth profile while rocky coasts have a fractal nature. One characteristic feature of a rocky coast is that new details appear when we zoom in on it. And if we were to measure the length of the coast, the length would increase significantly when zooming in on the details. Continue reading →

How to Reconcile the Growing Extent of Antarctic Sea Ice with Global Warming?

It is well known that sea ice has a significant influence on the Earth’s climate system. While global warming causes Arctic sea ice to melt at a measurable and significant rate, sea ice surrounding Antarctica has actually expanded, with record extent in 2010.

Ornithologists are at times limited in what they can measure by the very things that they are trying to observe: birds will sometimes actively avoid detection. Continue reading →

It may not be in the same place, may not be of the same strength or have the same temperature and salinity characteristics, but as long as the continents bound the great ocean basins, the sun shines, the earth turns toward the east and the wind blows in response, there will be a Gulf Stream.

The New Math

General, Mathematics
Posted on February 3, 2013 by Brian Conrey | Reply

Why has the MPE2103 movement been popular with mathematicians? The traditional view of mathematicians is that they like to work in solitude and that there is a great divide between pure and applied mathematicians. So how has MPE2013, a massive collaborative effort on the part of pure and applied mathematical scientists, managed to bridge this chasm? Continue reading →

The Discovery of Global Warming

General
Posted on January 19, 2013 by Hans Kaper | Reply
Joesph Fourier Jean Baptiste Joseph Fourier (1768-1830), French mathematician and natural philosopher, did groundbreaking work in mathematics and the theory of heat. He was the first to propose that the Earth's atmosphere acts to raise the planet's temperature.

“As a dam built across a river causes a local deepening of the stream, so our atmosphere, thrown as a barrier across the terrestrial rays, produces a local heightening of the temperature at the Earth’s surface.” Thus in 1862 John … Continue reading →
