Climate (from Ancient Greek κλίμα 'inclination') is commonly defined as the weather averaged over a long period. [9] The standard averaging period is 30 years, [10] but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.
The climate of Rajasthan in northwestern India is generally arid or semi-arid and features fairly hot temperatures over the year with extreme temperatures in both summer and winter. The hottest months are May and June .
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The atmosphere envelops the earth and extends hundreds of kilometres from the surface. It consists mostly of inert nitrogen (78%), oxygen (21%) and argon (0.9%). [4] Some trace gases in the atmosphere, such as water vapour and carbon dioxide, are the gases most important for the workings of the climate system, as they are greenhouse gases which allow visible light from the Sun to penetrate to ...
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
[7] [8] The first was Special Report on Global Warming of 1.5 °C, [9] and the third is the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) released on 25 September 2019. [10] [11] The AR6 cycle is considered by the IPCC to be their most ambitious since the panel was formed in 1988. [9]: 11 [Notes 1] [12]
Climate variability is the term to describe variations in the mean state and other characteristics of climate (such as chances or possibility of extreme weather, etc.) "on all spatial and temporal scales beyond that of individual weather events." Some of the variability does not appear to be caused by known systems and occurs at seemingly ...
