combustion of fossil fuels
Global Warming
There are basically three kinds of climate forcing:Forcing from Greenhouse gases.Other anthropogenic (man-made) forcing (soot, reflective particles, soil and dust, landcover changes like de- or re-forestation and human changes of clouds)Natural forcings like changes in the sun's energy and volcanic emissions.The one that has the least effect on global climate is Natural forcings.
A:Generating electricity from fossil fuels is the one human activity that contributes more than any other to increased atmospheric greenhouse gas levels and is therefore considered to be the main contributing factor in global warming. Thus, any human activity that creates an increased demand for electricity is effectively contributing to global warming. Next comes motor transport, because this requires us to burn oil, one of the main fossil fuels.
Yes. Global warming is causing climate change, meaning hotter, wetter, drier in different parts of the earth, with storms likely to be stronger. Ice melting is causing sea level rise causing threats of permanent flooding to low lying coastal areas.
The main way in which climate change is affecting koalas is that Australia is becoming prone to more frequent and intense bushfires which, of course, kill koalas. Eucalyptus bushland will always regenerate after a bushfire - that is the way Australian native plants are designed - but the impact on the koala population can be quite devastating. Koalas simply have nowhere to run and hide during a bushfire. Another way in which climate change can affect koalas is that, with increasing droughts that extend over a wider range and continue for longer, this does impact on healthy gum trees of the type favoured by koalas. As a consequence, koalas are more likely to wander beyond their home trees, which uts them at risk of being hit by cars or attacked by dogs.

No evidence disproves it. There is some evidence which at face value may seem to contraindicate human activity as the primary cause of global warming, but that evidence is most likely simply misinterpreted, in view of all the evidence supporting the hypothesis. One example was a recent study on cosmic rays. Editors at the Wall Street Journal jumped on this study as "proving" humans could not be responsible for global warming, even though the authors of the study could show no long term variation in cosmic ray bombardment, nor any significant impact of cosmic rays upon actual climate. In point of fact, in the opening paragraphs of that very study the authors acknowledged the human contribution to greenhouse gas emissions and their impact upon the global climate.
the current changes the temperature
Climate change is beginning to be seen in many places round the world. Recent record breaking heat waves have led scientists to say that it is "very likely" that these are being aggravated by global warming and climate change.
None. Not one disagrees that human activity is likely to be causing the present global warming.The last one to change its mind was, curiously, the American Association of Petroleum Geologists. In 1999 the statement on its website rejected the likelihood of human influence on climate change. This was replaced in 2007 with a non-committal statement of position.
Climate change is one of our greatest environmental, social and economic threats. The warming of the climate system is unequivocal, says the Intergovernmental Panel on Climate Change (IPCC). Observations show increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. It is very likely that most of the warming can be attributed to the emissions of greenhouse gases by human activities.
Climate Change (Global Warming). It's already happening, but it will get worse is the ozone continues to be destroyed.
Introducing global warming to preschool children would most likely just confuse them. A complex issue like global warming or climate change should probably be saved for an older age.
The farther that you live from an ocean, the more likely you will be living in a continental climate. A continental climate is a relatively dry climate with hot summers and cold winters.
Yes, social connections can significantly impact physical activity. People are more likely to engage in regular exercise when they have social support or workout partners, fostering accountability and motivation.
