newman, senior geoscience scientist at nasa's goddard space center and co-chair of the assessment panel that documented the recovery from it , says about the importance of this layer. oxygen is the bill with distance molecules are located on the surface and block harmful uv rays from the sun can break the biologically active bonds of molecules which can lead to things like skin cancer and cataracts so a healthy layer is necessary for life now 35 years later the history of the united nations assessment shows that the ozone layer is steadily recovering, and a large part of this layer is on the path to complete restoration by 2040. holes were first discovered in the 1980s, and by 1987, 46 countries had signed the montreal protocol. which is the reason for banning the production of so-called black gas what happened to these gases caused the destruction of the ozone layer and exposure of humans to harmful and damaging ultraviolet rays and causes diseases such as skin cancer. saving the ozone layer has positive effects on climate change because some of the gas the ones that have been removed

which acts as a blow to the gradual removal of paul newman, senior earth scientist at nasa's goddard space centerco-chair of the assessment panel that documented the recovery of the ozone , says the importance of this layer. the oxygen atom is big , this bill is located above the distance of the molecules and prevents harmful ultraviolet rays from the sun. these rays can break molecules into biologically active dyes that can lead to things like skin cancer and cataracts. therefore, a healthy ozone layer is necessary for life. five years after that, the evaluation date of the organization the united nations shows that the ozone layer is steadily recovering, and much of this layer is on track to be completely restored by 2040. holes were first discovered in the 1980s, and by 1987, 46 countries had signed the montreal protocol, which the reason for the production ban the gas became known as political gas, these gases cause the destruction of the ozone layer and the exposure of humans to harmful and damaging ultraviolet rays and diseases such as skin cancer. saving the ozone layer has positive effect

newman, senior earth scientist at nasa's goddard space center and co-chair of the assessment panel that documented the recovery from it , says about the importance of this layer, the oxygen atom is as big as this bill . with the distance of the molecules above us it blocks the sun's harmful ultraviolet rays, which can break the biologically active bonds of molecules that can lead to things like skin cancer and cataracts , so a healthy ozone layer is necessary for life. the united nations shows that the ozone layer is steadily recovering, and a large part of this layer is on track to be completely restored by 2040. holes in the ozone layer were first discovered in the 1980s, and by 1987, 46 countries had signed the montreal protocol, which caused prohibiting the production of flowers called cf thirty of these gases cause the loss of the ozone layer and expose humans to harmful and harmful ultraviolet rays and get diseases such as skin cancer. saving the ozone layer has positive effects on climate change because some of the gas the ones that have been removed are actually strong greenhous

of the things i find really inspirational is a lot of my students that when i was at the goddard space flight centere inspired to join nasa because of what we did with hubble and we will do the same with james webb. >> terrific, thank you. and as i yield back mr. chairman, because i can't stay for a second round, i just want to mention the importance of diversifying the workforce and making sure that the opportunity to work in this field is available, especially to those historically left behind. and i yield back. thank you mr. chairman. >> thank you very much. now ask unanimous consent on the committee to wave on ms. stansbury for without objection. let me now recognize online ms. stansbury for her questions. >> thank you so much mr. chairman, and thank you to the committee for letting me participate today. as folks have noted already on this hearing this morning, we're not only celebrating the findings of the webb telescope but also the successful launch of artemis one. and as a woman in stem, i want to just note that it's been led by an amazing group of women including charlie blackwell thompson
