global warming top stories

The impact on wildlife is a major top story. For instance, polar bears are losing their habitats as Arctic sea ice melts. Many species are being forced to migrate to new areas or face extinction. Also, coral reefs are dying off at an alarming rate. The warmer ocean temperatures cause coral bleaching, disrupting entire marine ecosystems. Additionally, deforestation, which contributes to global warming, is also a key story as it reduces the Earth's ability to absorb carbon dioxide.

Global warming photography was a photography theme with profound meaning. Many photographers were dedicated to recording the effects of global warming. In the Pastoruri Glacier in the Ancash region of the Andes Mountains in northern Mexico, photographer Reuben Wu and his team walked for four hours into the glacier after sunset to shoot. Due to global warming, the glaciers here have rapidly receded, shrinking by half in 2019. It has also caused the surrounding soil to be polluted and the land to become more barren. Reuben Wu cleverly used the drone to carry light sources to create highlights and shadows. By grasping the terrain and post-processing technology, he shot a work that struck the hearts of the people and recorded the evidence of serious glacier rupture and melting of ice and snow. American photographer J. Henry Fair, in his 20 years of photography, used his lens to record the scenes of global warming and environmental pollution. His works showed images of the earth's scars, such as aluminum smelting waste eroding the soil, mining metal waste destroying farmland, fertilizer radioactive substances polluting the environment, oil spill causing the death of marine life, refinery waste affecting health, pig farm drug hormone excrement mixture polluting underground water, and so on. In order to film the pollution inside the chemical plant, he overcame many difficulties and even used a helicopter to take aerial photos. Although the process was difficult, his work allowed people to see the truth behind the environmental problems. In the Svalbard archipelago in the Arctic region, a photographer from National Geography also reported on the matter. Due to global warming, the temperature here is rising three times faster than the global average, and the sea level has risen by 22 to 30 centimeters in the past 30 years. The photographer recorded the impact of climate change on the local environment behind the four seasons of the region, such as the melting of glaciers, rising sea levels, and the collapse of the ecosystem. Despite the unique beauty of the four seasons, such as bears and seals appearing in the gaps of the ice in spring, lush vegetation under the summer sun as a habitat for migrating birds, auroras in autumn adding mystery, and snow and polar animals in winter, the entire ecosystem is facing serious challenges. Through their works, these photographers not only recorded the changes in topography and ecology caused by global warming, but also urged people to reflect on the impact of human activities on the earth and called on governments, businesses and individuals to work together to address the serious problem of global warming. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Global warming is a long-term climate change phenomenon. Due to the increase in greenhouse gases such as carbon dioxide, methane, and freon, the concentration of these gases increased, causing the Earth's atmospheric temperature and ocean temperature to continue to rise under the greenhouse effect. Since the 20th century, with the expansion of human activities and the process of industrialization, global warming, melting of glaciers and snow mountains, rising sea levels, the re-distribution of the Earth's mass, and the increase in internal density may be one of the reasons for the acceleration of the Earth's rotation. The frequent occurrence of geological disasters in the 21st century would also cause the Earth's rotation to suddenly accelerate. According to the fifth assessment report of the Interpol released in 2013, there is a high probability that human activities will cause a disaster.(More than 95% probability) has caused most (more than 50%) of the global average surface temperature increase since the 1950s. Among them, greenhouse gases may have contributed 0.5 - 1.3 ° C between 1951 and 2010. Under a series of scenarios, the global average surface temperature will increase by 0.3 - 0.7 ° C between 2016 and 2035 compared to 1986 - 2005. Between 2081 and 2100, it would rise by 0.3 ° C to 4.8 ° C, and by 2100, the Earth's temperature could rise by more than 2 ° C (the threshold that governments have promised to maintain). Global warming was causing serious harm to the Earth's environment, such as the expansion of deserts, the collapse of polar ice shelves, the melting of permafrost, the retreat of glaciers, the sharp decrease in sea ice, the increase in extreme weather, the worsening of food and water scarcity, and the forced migration or even extinction of many species. Some people believed that although excessive greenhouse gas pollution contributed to global warming, the key reason was the gradual warming phase during the interglacial period (from slow warming to accelerated warming). Some scientists predicted that the Earth would dry up in 2166. In order to cope with global warming, governments of various countries worked together to take measures such as reducing energy pollution, and people were also saving energy and reducing pollution.

The global warming situation in 2024 was grim. In 2023, the global average surface temperature was 1.42 ° C higher than the pre-industrial level, and the average temperature in March 2024 was higher than that in 2023. The National Oceanic and Atmospheric Administration's 175-year record showed that 2024 had a 61% chance of becoming the " hottest year " and a 100% chance of being in the top five of the " hottest years." The World Meteorology Organization had repeatedly warned that climate change caused by human activities was becoming more and more intense. In 2024, in addition to high temperatures, extreme weather such as heavy rains and droughts would also appear. The winter of 2023 - 2024 was the warmest winter in the world. The global high temperature development has become a norm, and the extreme high temperature in 2024 may once again push the annual average temperature up. In addition, although global warming may increase the area and yield of food, it will also lead to adverse effects such as increased pests and diseases. It will also cause cracks in the southern hemisphere ice sheet, fracture of the Antarctic plate, and a decrease in the ice sheet area. If it is allowed to develop, there may be a temperature rise of 2.8 - 3 ° C by the end of the century, causing the sea ice in Greenland to melt completely and the sea level to rise by 2 - 7 meters.

At present, it is not certain whether global warming is irreversible. From the perspective of greenhouse gas discharge, human activities increased the discharge and concentration of carbon dioxide, methane, Freon, and other greenhouse gases, which was an important factor leading to global warming. Although governments worked together to reduce energy pollution, such as reducing energy use, replacing fossil fuel power generation with low-carbon energy, increasing wind, solar, and nuclear power generation, and people were also saving energy and reducing pollution, the accumulation of greenhouse gases in the past and the current state of pollution still had a continuous impact on the temperature. From the perspective of temperature changes and influencing factors, the global average temperature in 2023 was close to the pre-industrial level of 1.5 degrees Celsius. Although scientists took into account human greenhouse gases, the El Nino phenomenon, volcanic activity, changes in Earth's cloud cover, increased solar activity, volcanic release of water vapor, and reduction of airborne particles, there was still a 0.2 degrees Celsius temperature gap that could not be explained. Judging from the impact of global warming, it had caused many serious disasters, such as the expansion of deserts, the collapse of polar ice shelves, the melting of permafrost, the retreat of glaciers, the sharp decrease in sea ice area, the increase in extreme weather, the shortage of food and water resources, and the forced migration or extinction of species. Even if humans successfully alleviated the warming problem, its effects would last for centuries. These circumstances made it difficult for the global warming trend to be fundamentally reversed in the short term, but it could not be determined that global warming was irreversible.
