venus's atmosphere has much more carbon dioxide than earth's because
Atmosphere of Venus Unlike Earth, Venus lacks a magnetic field. Its ionosphere separates the atmosphere from outer space and the solar wind. This ionised layer excludes the solar magnetic field, giving Venus a distinct magnetic environment. This is considered Venus's induced magnetosphere. Lighter gases, including water vapour, are continuously blown away by the solar wind through the induced magnetotail.[4] It is speculated that the atmosphere of Venus up to around 4Â billion years ago was more like that of the Earth with liquid water on the surface. A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases.[8][9]

Carbon dioxide in Earth's atmosphere Over the past 400,000 years, CO2 concentrations have shown several cycles of variation from about 180 parts per million during the deep glaciations of the Holocene and Pleistocene to 280 parts per million during the interglacial periods. Each part per million by volume of CO2 in the atmosphere contains approximately 2.13 gigatonnes of carbon.[10] Currently CO2 constitutes about 0.041% (equal to 410 ppm) by volume of the atmosphere,[11][12] which corresponds to approximately 3200 gigatons of CO2, which includes approximately 870 gigatons of carbon. The global mean CO2 concentration is currently rising at a rate of approximately 2 ppm/year and accelerating.[13][14]
Okra Abelmoschus esculentus is cultivated throughout the tropical and warm temperate regions of the world for its fibrous fruits or pods containing round, white seeds. It is among the most heat- and drought-tolerant vegetable species in the world and will tolerate soils with heavy clay and intermittent moisture, but frost can damage the pods.
