Scientists at the University of Rochester, the University of Alabama, and the University of Virginia have said that the observed patterns of temperature changes over the last 30 years are not in accord with what greenhouse models predict. These observations are in conflict with the conclusions of the United Nations Intergovernmental Panel on Climate Change and also with some recent research publications based on essentially the same data.

New research from the University of Sheffield indicates that greenhouse gas emissions from petrochemical production could increase by 50 per cent by 2050 under a business-as-usual scenario. The study, published in Nature Sustainability, provides the first detailed global map of these emissions, identifying key sources and highlighting the challenge of decarbonising the sector.
IIT-Guwahati has partnered with Kaashyap Cleantech Innovations to commercialise bio-methanol production technology, which converts greenhouse gases into a versatile liquid fuel, offering environmental and performance benefits.
Researchers at IIT-Guwahati have developed an inexpensive and efficient catalyst for producing hydrogen from water, a crucial step for the National Green Hydrogen Mission and the transition to sustainable energy. The catalyst uses nickel salt and an anthracene-based organic molecule, offering a cleaner alternative to fossil fuel-derived hydrogen.
According to the amendment adopted by nations, developed countries will reduce HFCs use first, followed by China along with a large number of countries.
A new study reveals that past emissions from major oil, gas, coal, and cement producers will continue to impact Earth's environment for centuries, even if emissions cease today. The research highlights that the planet will remain significantly warmer than pre-industrial levels, leading to persistent climate damages and increasing the likelihood of future extreme weather events, forming the basis for accountability lawsuits against these "carbon majors."
Despite that India has taken to further steps to cut down these emissions, he said, pointing out that the primary energy consumption growth rate is 3.4 per cent per year against GDP growth rate exceeding 9 per cent.
India and China are in what experts call 'a cooperation-versus-competition situation'.
Researchers have discovered that Delhi's urban forests are significant carbon sinks, storing substantial amounts of carbon in trees and soil, with the potential to generate revenue through carbon credits. The study highlights the importance of preserving and expanding these forests to combat climate change.
iPhone maker Apple has met its replenishment target for freshwater withdrawals for corporate operations in India in 2023, the company said in its environmental progress report released on Wednesday. Globally, Apple has set a goal to replenish 100 per cent of corporate freshwater withdrawals in high-stress locations by 2030.
New deal to curb carbon emissions could copy features from the Montreal Protocol, which US and China favoured over its Kyoto counterpart.
'Can you believe there are over 26,500 deaths linked to heatwave-driven ozone in 2024?'
The ministry stated that for vehicles designed for E10 and calibrated for E20, mileage may drop by just 1-2 per cent, while in other vehicles, it could be around 3-6 per cent.
India's new climate pledge to the UN could be weakened by its growing use of coal, even as the country plans a 2035 roadmap to cut emissions and boost clean energy.
The chemical -- perfluorotributylamine -- is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate, said researchers from University of Toronto's Department of Chemistry.
How the UN's flagship climate summit lost its direction and what's at stake.
Cities around the world account for 71 per cent of the world's greenhouse gas emissions.

Let's take a look at some of the most polluted places in the world.
Proposals are being worked upon at the Copenhagen summit to cut the greenhouse gas emissions in the atmosphere, prominent among which is the use of nuclear energy.
A national network project, run by the Indian Council of Agricultural Research since 2004, carried out to study the impact of climate change on Indian agriculture, is also throwing some light on the complex inter-relation between CO2, global warming and crop productivity.
Carbon credits are a tradable permit scheme. They provide a way to reduce greenhouse gas emissions by giving them a monetary value.
Steel-making results in vast amounts of carbon, and belching flame and smoke. But a new process developed by Massachusetts Institute of Technology researchers could change all that.
In the last 100 years, the earth's average surface temperature rose by about 0.8 degree Celsius with about two thirds of the increase occurring over just the last three decades.
You can do small things and bring about big changes to make your planet live longer...
While governments and corporations are taking steps to reduce greenhouse gases, individuals, too, can pitch in to make this world a better place for present and future generations.
Some of the world's biggest polluters, the US, China, European Union and India, have reiterated their previous pledges of cutting emissions by 2020 that were widely regarded as weak, especially the 17 per cent reduction of carbon emissions from 2020 levels proposed by the US.
The energy security and climate conference of the world's major economies, including India and China, will begin in Washington on Thursday to discuss the issues related to global warming.
Accumulation of atmospheric brown clouds caused by the buildup of greenhouse gases is significantly contributing to the melting of Himalayan glaciers.
The number of carbon credits or certified emission reduction (CERs) issued for a cut in the release of greenhouse gases into the environment is set to triple in India over the next three years, due to a rising number of claims from rapidly growing renewable energy (RE) projects.
"Nargis is a sign of things to come. Last year, Bangladesh was devastated by the tropical cyclone Sidr," said Narain. "The victims of these cyclones are climate change victims and their plight should remind the rich world that it is doing too little to contain its greenhouse gas emissions," Sunita Narain, director, Centre for Science and Environment, said.
The wedding of Prince William and his girlfriend Kate Middleton is likely to generate more than 10 times as much greenhouse gases the Buckingham Palace emits in a whole year, a carbon footprint analysis has predicted.
ArcelorMittal, the world's largest steel maker, will benefit from a windfall of 1 billion (Rs 7,000 crore), thanks to the carbon credits issued to it under the European Trading Scheme. The Sunday Times today reported that ArcelorMittal will be the single largest beneficiary under the ETS due to its dominant presence in Europe.
The 'Civil Society Report on Climate Change' prepared by the Civil Society Coalition on Climate Change -- a conglomerate of 40 scientific think-tanks from as many countries, including the US, the UK and Italy -- that was released today clearly says that 'cutting greenhouse gas emissions in the coming two decades is not a cost-effective way to address climate change". The report was released by deputy chairperson of the Planning Commission, Montek Singh Ahluwalia.
