Black carbon is a microscopic air pollutant \u2014 a residue from fossil fuel and biomass combustion (such as forest fires). When it settles on Greenland\u2019s ice sheet, it darkens the surface and, since dark colors absorb more sunlight, accelerates melting. We say that it affects Greenland\u2019s albedo by reducing its ability to reflect sunlight.    <\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; width=&#8221;90%&#8221; max_width=&#8221;90%&#8221;][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][et_pb_image src=&#8221;https:\/\/matthieutordeur.com\/wp-content\/uploads\/2025\/01\/Expedition-Groenland_Heidi-05.jpg&#8221; title_text=&#8221;Expedition-Groenland_Heidi-05&#8243; show_bottom_space=&#8221;off&#8221; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; text_font=&#8221;||on||||||&#8221; text_font_size=&#8221;14px&#8221; text_line_height=&#8221;1.4em&#8221; header_text_align=&#8221;center&#8221; custom_margin=&#8221;5px||||false|false&#8221;]<\/p>\n<p>Every morning, the same ritual: analyze the wind strength to choose the right kite, lay it out carefully, and make sure all the lines are untangled&#8230;<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][et_pb_image src=&#8221;https:\/\/matthieutordeur.com\/wp-content\/uploads\/2025\/01\/Expedition-Groenland_Matthieu-044-e1737494636514.jpg&#8221; title_text=&#8221;Expedition-Groenland_Matthieu-044&#8243; show_bottom_space=&#8221;off&#8221; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; text_font=&#8221;||on||||||&#8221; text_font_size=&#8221;14px&#8221; text_line_height=&#8221;1.4em&#8221; header_text_align=&#8221;center&#8221; custom_margin=&#8221;5px||||false|false&#8221;]<\/p>\n<p>\u2026and finally, take off!<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; width=&#8221;90%&#8221; max_width=&#8221;90%&#8221;][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][et_pb_image src=&#8221;https:\/\/matthieutordeur.com\/wp-content\/uploads\/2025\/01\/Expedition-Groenland_Matthieu-019.jpg&#8221; title_text=&#8221;Expedition-Groenland_Matthieu-019&#8243; show_bottom_space=&#8221;off&#8221; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; text_font=&#8221;||on||||||&#8221; text_font_size=&#8221;14px&#8221; text_line_height=&#8221;1.4em&#8221; header_text_align=&#8221;center&#8221; custom_margin=&#8221;5px||||false|false&#8221;]<\/p>\n<p>La tente est aussi bien un refuge contre les \u00e9l\u00e9ments qu\u2019un rempart contre l\u2019immensit\u00e9.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][et_pb_image src=&#8221;https:\/\/matthieutordeur.com\/wp-content\/uploads\/2025\/01\/Expedition-Groenland_Matthieu-038.jpg&#8221; title_text=&#8221;Expedition-Groenland_Matthieu-038&#8243; show_bottom_space=&#8221;off&#8221; _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.9.10&#8243; _module_preset=&#8221;default&#8221; text_font=&#8221;||on||||||&#8221; text_font_size=&#8221;14px&#8221; text_line_height=&#8221;1.4em&#8221; header_text_align=&#8221;center&#8221; custom_margin=&#8221;5px||||false|false&#8221;]<\/p>\n<p>The tent serves both as shelter from the elements and as a barrier against the immensity of the landscape.
