According to NASA’s analysis of the Earth’s average surface temperature in 2023, it was the warmest on record to date as revealed in January 12. Last year, the global temperatures were 1.2 degrees Celsius above the average temperature. With this significant new development in the climate crisis, researchers are left wondering as to what is to come and what it means for the environment and atmosphere in the years to come.
The records all the way back to 1850 reveal that 2023 was the warmest with a record high ocean temperature and also a new low for the Antarctica sea ice extent. In fact, the last decade itself has been the warmest recorded and each decade in the past 40 years has been warmer than the previous one. What made last year’s temperatures worse was El Nino, the periodic climate event that renders parts of Pacific Ocean hotter and consequently increases global temperatures.
In 2023, scientists were surprised by the unprecedented severity of global warming, which deviated significantly from the expected long-term pattern. The year started following projections but took an alarming turn in the second half, breaking numerous temperature records.
Ongoing Climate Crisis and Human Impact: Warmest Year 2023
The National Oceanic and Atmospheric Administration had also reported that 2023 has broken the previous record set in 2016 by a substantial margin of 0.15°C. Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, has admitted the challenge of explaining the extreme warmth. He noted that the year was “off the charts,” and it raised concerns. He also added that last year marked the first time he felt less confident in understanding climate dynamics. Noaa’s chief scientist, Sarah Kapnick, described the findings as “astounding” and also highlighted the urgent need for a deeper understanding of the unprecedented climatic events in 2023 especially after it was declared ‘warmest’.
The fact that so many climate and environment researchers are feeling underconfident regarding the climate crisis is in actuality quite alarming. Despite, numerous calls and attempts made to spread awareness, the gravity of the issue fails to be understood by most. The climate change crisis is being made use of by the capitalists to sell their own agenda instead. Selling more expensive environmentally friendly and sustainable items has become a ploy instead of focusing on factors that really matter or making sustainable products that are universal and lower priced.
Furthermore, there have also been warnings that 2024 has a 50-50 chance of becoming the warmest year on record. This is attributed to the El Nino which is expected to heighten, and the probability of limiting global warming to 1.5°C, crucial to preventing severe heatwaves, floods, and droughts, is almost nonexistent. Schmidt shed light on the fact that human activities, particularly the emission of greenhouse gases, are leaving a significant and lasting impact on the planet. He compares this influence to the historical impact of cyanobacteria and has highlighted the urgency of addressing climate change caused by human actions.
International Response and Transition Away from Fossil Fuels
The alarming increase in global temperatures has broken the annual record. It has also created the urgent need for calls for urgent action against the climate crisis with 2023 being the warmest year. Despite pledges made at the United Nations climate talks in Dubai, the transition away from fossil fuels remains insufficient. With record-breaking emissions and extensive oil and gas drilling projects continuing worldwide without an end in sight, the climate crisis is getting out of hand.
The devastating impact of climate related disasters in 2023, such as wildfires in Hawaii and flooding in Libya, underscored the urgent need for action. António Guterres, UN Secretary-General, emphasized that human activities are scorching the earth, urging immediate and unprecedented measures. The World Meteorological Organization has stressed the imperative for drastic greenhouse gas emission reductions and a swift transition to renewable energy sources.
NASA determines global temperatures using data from weather stations and instruments on ships and buoys. They consider factors like station spacing and urban heat. Other organizations, like NOAA and the Hadley Centre had both confirmed that 2023, the warmest so far, had the highest global temperatures on record. Despite some differences, they agree on the long-term warming trend. The U.S. Greenhouse Gas Center, started by the Biden-Harris Administration, shares essential climate data. NASA’s temperature dataset through 2023 is available online and is aimed at fostering collaboration and providing easy access to environmental information for decision-makers and the public. The record-breaking temperatures of 2023 underscore the severity of the ongoing climate crisis, demanding immediate and unprecedented global action.
