Sökning: "greenhouse gases radiative forcing"
Visar resultat 1 - 5 av 10 avhandlingar innehållade orden greenhouse gases radiative forcing.
1. Non-CO2 greenhouse gases, uncertainty and land-use competition
Sammanfattning : Over the past 250 years the concentrations of greenhouse gases in the atmosphere have increased drastically. It is close to scientific consensus that these changes have increased the temperature of the earth. LÄS MER
2. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models
Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER
3. Historical anthropogenic radiative forcing of changes in biogenic secondary organic aerosol
Sammanfattning : Human activities have lead to changes in the energy balance of the Earth and the global climate. Changes in atmospheric aerosols are the second largest contributor to climate change after greenhouse gases since 1750 A.D. LÄS MER
4. Instruments for reaching climate objectives. Focusing on the time aspects of bioenergy and allocation rules in the European Union's Emission Trading System
Sammanfattning : The Europeans Union’s (EU’s) climate and energy strategy aims at reducing the emissions of greenhouse gases (GHG) by 20 % (compared to 1990) and to increase the share of renewable energy to 20 % by the year 2020. Increased use of bioenergy is considered key in these efforts. LÄS MER
5. Microbial mitigation of greenhouse gas emissions from boreal lakes
Sammanfattning : The climate change crisis has drawn the attention of both the public and scientific community to the carbon cycle and particularly to the importance of greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4). CO2 has been a key component of Earth´s climate regulation throughout its geological history and is now the main driver of the current change in climate. LÄS MER
