In 2030, the global average temperature is projected to be approximately 0.4°C to 1.1°C warmer than the 1986–2005 average. The world is also likely to exceed the 1.5°C warming threshold above pre-industrial levels on a long-term decadal average around that year.
30 in Proceedings of the National Academy of Sciences, provides new evidence that global warming is on track to reach 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial averages in the early 2030s, regardless of how much greenhouse gas emissions rise or fall in the coming decade.
If annual emissions increase more slowly and begin to decline significantly by 2050, models project global temperatures would still be at least 2.4 degrees warmer than the first half of the 20th century, and possibly up to 5.9 degrees warmer.
Global Temperatures Expected to Rise 2ºC by 2030. Global temperatures are set to rise 2ºC by 2029 according to a new WMO report, with the increasing frequency of 1.5ºC+ years and the potential for an unprecedented 2ºC year.
The mobile-friendly MyClimate 2050 tool shows almost all areas across Australia will experience longer and hotter summers, with temperatures increasing by an average of 2.32°C.
By 2070, average Australian temperatures are projected to increase by about 1.8 °C in a low emissions scenario, with a range of 1.0-2.5 °C across the country. In a high emissions case the projected average temperature increase is about 3.4 °C, with a range of 2.2-5.0 °C, relative to 1990.
Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
In its 2022 report, the IPCC estimated that humanity could only emit 500 billion more tonnes of CO2 from the start of 2020 onwards for a 50% chance of keeping warming to 1.5C. As a result, the remaining carbon budget would be exhausted “in a little more than three years if global CO2 emissions remain at 2024 levels.”
All of the top 10 warmest years have happened in the past two decades. With a mean temperature of 10.09C, 2025 now tops the list, with 2022 and 2023 the second and third warmest years since records began in 1884. It was only the second time since the 19th century that the mean temperature exceeded 10C.
Summers are getting hotter — and longer
The hottest days of the year are getting even hotter because of climate change. Recent analysis shows that heat-trapping pollution — mainly from burning coal, oil, and gas — has fueled the rise in summer's extremely hot days and dangerously warm nights over the last 55 years.
Though the climate of Earth will be habitable in 2100, we will be experiencing new extremes. Each decade will be different from the previous and next decade. The climate future could be quite bleak.
Energy and Heat
Modern AI data centers can use as much electricity as a small city. And it's not just the computing that eats up power. Memory and cooling systems are major contributors, too. As AI models grow, they need more storage and faster access to data, which generates more heat.
🏜️ Australia's desert interior Our continent is mostly dry land that heats up fast and stays hot. That heat radiates outward and amplifies temperatures across the country. 🌬️ Few major mountain ranges With minimal topography to block or redirect air masses, hot air just flows freely across the continent.
The 2030 Agenda is a continuation of the UN Millennium Development Goals (2000-2015) which were in their day the first international consensus on facing global problems such as the eradication of extreme poverty and hunger, and to promote improvements in access to education.
2030 is considered a critical deadline, a "point of no return," for climate action because scientists warn that surpassing 1.5°C (2.7°F) of global warming around that time risks triggering irreversible "tipping points," like melting permafrost releasing methane or Amazon rainforest dieback, leading to self-reinforcing warming loops that humanity can't stop, making catastrophic climate change much harder or impossible to avoid, even with future emissions cuts, according to reports from the UN IPCC, Science News and other experts.
No, 2025 was generally not hotter than 2024 globally, with 2024 holding the record as the warmest year, but 2025 was still exceptionally hot, ranking as the second or third warmest year on record, slightly cooler due to fading El Niño but continuing a severe warming trend. Early 2025 saw record heat in some areas, but as the year progressed, a shift towards La Niña conditions meant temperatures dipped slightly below 2024's peaks, though still far above historical norms.
Assuming the sun is a perfect black body , increasing the sun's temperature by 1% increases its power output by 4%. This means the 'solar constant' - the roughly 1400 W/m2 of power received at the earth's surface - will increase by 4% and so the earth will radiate that 4% more power when in thermal equilibrium.
Climate Change Over the Past 100 Years. Global surface temperature has been measured since 1880 at a network of ground-based and ocean-based sites. Over the last century, the average surface temperature of the Earth has increased by about 1.0o F.
Poor land management (farming techniques) across the Plains furthered the impact of the drought, with lush wheat fields becoming barren waste lands. Without the vegetation and soil moisture, the Plains acted as a furnace. The climate of that region took on desert qualities, accentuating its capacity to produce heat.
The Science Is Clear
It will never be too late to take meaningful action to protect people and the planet. However, decades of increasing carbon emissions from oil, gas and coal are harming the natural and social systems upon which all humanity depends, threatening devastation.
Dr Ian Pearson claims those who live till 2050 may escape death, as future science could replace damaged organs and possibly grant eternal youth. Dr. Ian Pearson suggests that advances in gene therapy, stem cells, nanomedicine, and cell reprogramming could enable eternal life by 2050.
There is still a chance for the world to avoid the worst ravages of climate breakdown and return to the goal of 1.5C if governments take concerted action on greenhouse gas emissions, a new assessment argues.
A future of heat-adaptive technologies including robotic agriculture and green buildings with minimal human presence due to the need for personal protective equipment. Parts of the Earth will be uninhabitable by 2500 if the current level of effort to address the climate crisis is maintained, a new study predicts.
A 3°C increase in global temperatures would be a world vastly different from the one we know today. It would be a world of devastating heatwaves, disasters, famine, species loss, and massive displacements.
National Geographic produced its own interactive feature in 2020 that takes a look at what the world will feel like in 50 years: By the 2070s, it shows Boston will feel more like Bardwell, Kentucky, with summers averaging 8°F hotter; and London will feel more like Sovicille, Italy, with summer temperatures rising 6°F.
