Silicate weathering reactions remove carbon dioxide from the atmosphere and store it in carbonate minerals. During the high atmospheric carbon dioxide conditions of the Early Eocene Climatic Optimum, rates of chemical weathering, physical erosion and denudation in the western USA were equivalent to the highest recorded rates in the non-glacial Quaternary.
Fjords line mountainous continental margins where icesheets and glaciers once stood. A two-dimensional model simulation suggests that fjords can be eroded within one million years, primarily in response to topographic ice steering and erosion from ice discharge. Subsequent glaciers that form on these landscapes are smaller and exhibit greater responses to climate change.
Using projected boundary conditions for the end of the twenty-first century, the frequency of Atlantic tropical cyclones and hurricanes in a regional climate model of the Atlantic basin is reduced compared with observed boundary conditions at the end of the twentieth century. This is inconsistent with the idea that higher levels of atmospheric greenhouse gases will result in increased Atlantic hurricane activity.
The termination of the Marinoan glaciation 635 million years ago is one of the most spectacular climate change events ever recorded. Methane release from equatorial permafrost might have triggered this global meltdown.
What should we do about climate change? The question is an ethical one. Science, including the science of economics, can help discover the causes and effects of climate change. It can also help work out what we can do about climate change. But what we should do is an ethical question.
Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate. This report provides current assessments of climate change science to inform public debate, policy, and operational decisions.
The Garnaut Climate Change Review was required to examine the impacts of climate change on the Australian economy, and to recommend medium- to long-term policies and policy frameworks to improve the prospects of sustainable prosperity. This draft report describes the methodology that the Review is applying to the: evaluation of the costs and benefits of climate change mitigation; application of the science of climate change to Australia; international context of Australian mitigation, and Australian mitigation policy.
This report offers a comprehensive analysis of a suite of climate policy initiatives associated with a cap and trade program with the goal of identifying those empirical and design issues that most influence the economic consequences of their enactment. Empirically, present-value policy costs heavily depend on the actual outcomes of household consumption-saving and labor-leisure decisions, the magnitudes of and any induced changes in sectoral demand elasticities and technological trends, and the resulting time paths of permit prices and market interest rates.
Tajikistan is battling a locust invasion, which the government says, has come a month earlier than usual. The infestation was first reported in southern districts of Tajikistan on March 18.
