Question

esaay on golobal warming and importance of ges

Answer 1

Greenhouse gas concentrations have continued to increase in the atmosphere. This is due largely to human activities, mostly fossil fuel use, land-use change, and agriculture. About 47% of the warming effect of greenhouse gas increases over the last 100 years is due to carbon dioxide.

Answer 2

The history of climate change science began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified.[64] In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate. In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing.[282] By the 1990s, as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages, a consensus position formed: greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming. Since the 1990s, scientific research on climate change has included multiple disciplines and has expanded.[283] Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change. hope it is useful......
